Hoses are sized according to the fittings for which they are designed. They have precise ID and OD so that they match up perfectly with their respective hose end. Definitely don’t attempt to mix sizes, this won’t work and can result in leakage or a fire. Our hoses are available in several different styles – rubber push lock, nylon braided, stainless steel braided, PTFE. Let’s review each style.
Rubber push lock hose is very useful for applications where the pressure is not very high, the hose will not be near any sources of high heat, and the fluids flowing through it aren’t very hot. Perfect for things like vacuum hoses, coolant hoses, catch cans, etc. While you can certainly use these hoses for fuel and oil, as their pressure, temperature, and chemical ratings are more than suffice for those fluids, due to the risk of damage or fire in the event of an accident or hose damage, we recommend going with a braided hose. Automotive fuels are extremely flammable, and if you were using the hose for oil and it became damaged, it could result in a loss of oil pressure and damage to your engine or transmission. These hoses are rated for up to 250 PSI depending on size, and are sized to only work with push lock hose ends. Do not attempt to use a swivel hose end with these fittings, they aren’t sized for that application.
Part numberHose IDOD (mm)Max Op. PSIMin/Max Op. TempMin Bend Radius RBH-4AN6.35mmThis is our most popular style of hose. These hoses use a CPE synthetic rubber liner surrounded by a thin stainless steel inner braid for strength, and is then bound by a thick nylon outer braid. These hoses are very lightweight, very flexible, abrasion resistant, corrosion resistant, less likely to ground on exposed wires, and are compatible with fuels like ethanol and methanol. These hoses are rated for up to 500 PSI depending on the size.
Part numberHose IDOD (mm)Max Op. PSIMin/Max Op. Temp NYL-4AN5.4mmStainless steel braided hose isn’t as popular as it used to be, having fallen in favor of nylon braided hose. These also use a CPE synthetic rubber liner with a thin stainless steel inner braid, but instead of being wrapped in a nylon braid, it’s got a thick, strong stainless steel braid. This makes the hose very strong and able to handle higher pressures, but the tradeoff is that they are heavier, less flexible, and can possibly ground exposed wires. Care must be used when routing these hoses as while they are very abrasion-resistant, they can cause damage to the parts that they are in contact with over time. On our 240SX racecar, we had oil cooler hoses in contact with our intercooler piping, and it nearly caused a hole to be worn all the way through! These hoses are compatible with ethanol and methanol based fuels and are rated for up to 1,000 PSI depending on size.
Part numberHose IDOD (mm)Max Op. PSIMin/Max Op. Temp SSBH-4AN5.4mmThis is our ultimate hose. These use a teflon liner with a thin stainless steel inner braid and a nylon outer braid. These hoses can handle extremely high pressures and temperatures and are impervious to almost any chemical, and are the recommended hose for use with ethanol, methanol, power steering, braking systems, and nitrous systems. Due to it’s construction it is limited in it’s bend radius and can’t be routed through tight spaces very well. These hoses are rated for up to 4,000 PSI depending on size.
