FAQ'S

What applications use straight heavy-duty hoses?
Straight hoses are commonly used for coolant lines, charge air connections, heater circuits, and jumper segments where no bends are required. They provide a simple, direct path between two fixed points.

How do I select the correct straight hose size?
Measure the inner diameter (ID) and wall thickness needed, then confirm the correct length. Use OEM part numbers or measure your existing hose to match the proper specs.

Are your straight hoses reinforced?
Yes. Our heavy-duty straight hoses are typically reinforced with high-strength textile or braided layers to withstand high pressure, vacuum, and thermal cycling without collapsing or bursting.

What temperature and pressure can these HD hoses handle?
They are designed for extreme environments—usually rated from well below freezing to high heat (e.g. –60 °F to 400 °F or more) and pressures compatible with coolant, charge air, or boost systems.

Can I trim these hoses to length?
Yes, in many cases straight hoses can be cut to the exact length needed. Be sure to use proper cutting tools and finish clean, square edges before installing clamps or couplings to ensure proper sealing.
