If you’ve ever stood in a manufacturing plant, a construction site, or even a local garage and watched a hose doing heavy lifting—whether it’s moving pressurized water to a concrete pump, air to a pneumatic tool, or chemicals to a processing line—you know not all hoses are created equal. As the owner of a hose supply company that focuses on specialty, lesser-discussed hose lines (what many in the industry just call “other hoses,” the ones that don’t fit the big, well-known categories like garden hoses or hydraulic hoses), I get asked this question all the time: “What pressure ratings do other hoses have?” It’s not a trivial question, either. Pick the wrong hose for the pressure you’re working with, and you’re looking at a leak, a shutdown, or even a safety hazard that can hurt people and cost thousands in downtime. Other Hoses
Let me start by clarifying one thing right off the bat. “Other hoses” isn’t a formal category from any industry standard group like the Hose Manufacturers Association (HMA) or the International Organization for Standardization (ISO). It’s what we use to describe the vast, varied group of hoses that aren’t hydraulic, pneumatic, water, or general-purpose garden hoses. That includes things like chemical transfer hoses, steam hoses, food-grade hoses, petroleum transfer hoses, and specialized industrial hoses for mining, agriculture, and pharmaceutical production. Each of these has completely different pressure ratings, and getting them right is the difference between a job that runs smoothly and one that goes off the rails.
Let’s break this down by the most common types of “other hoses” our team supplies, because that’s where most people run into confusion. First up: chemical transfer hoses. These are the hoses that move everything from mild cleaning solutions to harsh acids and industrial solvents from one tank or processing unit to another. Their pressure ratings are all over the place, depending on what they’re made to carry and the environment they’re used in. For example, a hose designed for moving dilute bleach or low-concentration ammonia might have a working pressure of 100 to 150 psi. That’s enough for most bulk transfer jobs where you’re just pumping liquid at a steady, moderate rate. But if you’re dealing with higher-concentration chemicals, or pumping them through a system that requires forced flow at higher speeds, that rating jumps. A chemical transfer hose for hydrochloric acid or concentrated sulfuric acid might have a working pressure of 200 to 300 psi, and some heavy-duty versions for industrial processing can go as high as 500 psi. The key here is that the pressure rating is tied to both the hose’s material (EPDM, PVC, or specialized synthetic rubbers like Neoprene) and its construction—most have multiple reinforcement layers of polyester or steel braid to hold up to pressure and chemical degradation.
Next, steam hoses. These are used for everything from cleaning large industrial equipment to heating process tanks in food processing plants. Steam is tricky because it’s not just pressurized—it’s also hot, often up to 350 degrees Fahrenheit or higher. The pressure ratings for steam hoses are specific to the temperature you’re working with, because pressure ratings drop as temperature rises. A low-pressure steam hose for general cleaning might have a working pressure of 150 psi at 330 degrees F. But if you’re dealing with superheated steam for process heating, that rating goes up to 250 psi at 350 degrees F, and some heavy-duty steam hoses used in power plants or refineries have working pressures of up to 300 psi at 375 degrees F. What surprises a lot of first-time buyers is that you can’t just swap a water hose for a steam hose. Water hoses are rated for pressure, but they’re not built to withstand the heat of steam, so even if the pressure matches, the hose will fail quickly and dangerously.
Food-grade hoses are another big part of our “other hoses” line. These are used in breweries, wineries, dairy farms, and food processing plants to move everything from milk and juice to cooking oils and syrups. Their pressure ratings are regulated by organizations like the FDA, which don’t just care about the material being safe for food—they also set strict standards for pressure performance. Most food-grade hoses used for low-viscosity liquids like water or juice have a working pressure of 100 to 150 psi, which is perfect for gravity-fed systems or low-pressure pumping. But for moving thicker products like syrup, chocolate, or dough mixes (yes, we supply hoses for dough transfer in bakeries!), the working pressure is higher, usually 200 to 250 psi. And for high-pressure cleaning of food processing lines, we also carry high-pressure food-grade hoses with ratings up to 500 psi, designed to withstand the force of hot water and cleaning chemicals used in CIP (Clean-in-Place) systems.
Petroleum transfer hoses are another common “other hose” that a lot of people don’t fully understand. These hoses move gasoline, diesel, and other petroleum products in industries like trucking, construction, and marine work. The pressure ratings here are a balance between safety and functionality. Most general-purpose petroleum transfer hoses have a working pressure of 100 to 150 psi, which is enough for fuel delivery trucks and small storage tank transfers. But for heavy-duty applications like refueling construction equipment mid-job, or marine fuel transfer, we carry hoses with working pressures of up to 300 psi, designed to handle the higher flow rates and consistent pressure of heavy industrial use. It’s worth noting that these hoses have to meet specific standards from agencies like the EPA, because they’re moving flammable materials, so their pressure ratings and construction (usually with static-dissipative layers to prevent sparks) are non-negotiable.
Now, I want to talk about something that a lot of buyers get wrong: the difference between working pressure and burst pressure. That’s critical when you’re figuring out what pressure rating you need. Working pressure is the maximum pressure a hose is designed to handle on a regular basis, during normal operation. Burst pressure is the pressure at which the hose will actually rupture, which is always a much higher number—usually 4 to 6 times the working pressure. For example, a chemical transfer hose with a 150 psi working pressure will have a burst pressure of 600 to 900 psi. That extra margin is there for safety, but that doesn’t mean you should operate the hose anywhere near its burst pressure. We always tell our customers to size their hose for the maximum pressure they expect in their system, and then add a 20-30% safety margin to that. So if your pump runs at 100 psi, don’t buy a hose rated for 100 psi—buy one rated for at least 120 or 130 psi. That little buffer will save you from surprises if your system’s pressure spikes unexpectedly, which happens more often than people think.
Another thing that affects pressure ratings: the length of the hose and any fittings you’re using. A lot of times, a customer will come to us with a hose they bought from a big box store, tell us it’s supposed to handle 200 psi, and wonder why it’s leaking on their 150 psi system. The issue is that long hose runs create friction loss. If you have a 50-foot hose vs. a 200-foot hose, the longer one will have more resistance to the flow of liquid or air, which can lower the effective pressure at the end of the hose. But if you’re pumping a high-viscosity liquid like oil, that friction loss is even higher, so you might need a hose with a slightly higher pressure rating to compensate. Also, fittings matter. If you use cheap, incompatible fittings that don’t seal properly, that can create a pressure drop at the connection point, or even cause the hose to fail at the fitting, even if the hose itself is rated for the right pressure. We always recommend matching fittings to the hose and the system, and our team will help you calculate friction loss based on your hose length and the material you’re moving, so you get the right pressure rating without overspending.
I’ve been in the hose supply business for 12 years, and I’ve seen every mistake you can make when it comes to pressure ratings. Last year, we had a customer in the mining industry who had bought a generic rubber hose for moving compressed air to a rock drill. He came to us after the hose burst, and he was lucky no one got hurt. The hose he’d bought was rated for 200 psi working pressure, but his rock drill runs at 250 psi, and he’d used a 100-foot hose run, which added another 30 psi of friction loss. So he was putting 280 psi through a hose rated for 200 psi—no wonder it failed. We swapped him out for a heavy-duty pneumatic hose rated for 400 psi working pressure, and added a pressure regulator to his system to keep it from spiking. That job has been running smoothly ever since.
Another example: a small chemical manufacturing plant that was using garden hoses to transfer dilute cleaning solution. They thought the solution was only 50 psi, so their garden hoses (rated for 100 psi) should work. But the pump they were using was pushing 120 psi, and the garden hoses aren’t built to handle consistent chemical exposure. Within six months, three of their hoses had cracked, leaking solution all over their production floor, forcing a shutdown that cost them $15,000 in lost production and cleanup. We supplied them with chemical-resistant transfer hoses rated for 200 psi, specific to the chemicals they use, and that’s eliminated the leaks. That’s why we don’t just sell hoses—we work with our customers to figure out exactly what pressure, material, and construction they need, because one size rarely fits all in “other hoses.”
Now, let’s talk about how pressure ratings are tested and standardized, because that’s a common question too. Most “other hoses” are tested to standards set by organizations like the HMA, ISO, and specific industry groups. For example, chemical transfer hoses are tested to ISO 14424, which specifies how to test their pressure resistance and chemical compatibility. Steam hoses are tested to ISO 6145, and food-grade hoses to FDA 21 CFR Part 177.2600, which includes pressure testing as part of the certification process. That means when you buy a hose that’s rated to a specific standard, you can trust that the pressure rating is accurate, not just a number printed on the side of a cheap hose. We only carry hoses that are certified to these standards, because we don’t want our customers dealing with the safety risks of unrated or misrated hoses.
I know a lot of buyers out there will look for the cheapest hose they can find, but when it comes to pressure ratings, cutting corners is a bad idea. A hose that’s rated for 100 psi that’s actually only tested to handle 100 psi in ideal conditions will fail if there’s a pressure spike, a little chemical degradation, or even if it’s run over by a forklift (which is common in industrial settings). We always tell our customers to invest in a hose that’s rated for at least 20% more than their maximum operating pressure, certified to a recognized standard, and designed for the specific material and environment they’re working in. The extra cost upfront is nothing compared to the cost of a shutdown, an injury, or replacing damaged product.
At the end of the day, “other hoses” are the unsung heroes of industrial operations. They’re not the fancy hydraulic hoses that get all the press, but they’re the ones that move everything from food to fuel to chemicals every single day. Their pressure ratings vary wildly based on their purpose, construction, and the conditions they’re used in, and getting that right is non-negotiable.
