Russell ProClassic -4 AN black hose on a 100 ft roll uses a lightweight nylon fiber outer braid over a durable rubber core with a 350 psi maximum pressure rating. It’s designed to be lighter and easier to assemble than traditional braided steel hose, suitable for fuel, oil or antifreeze plumbing, and is straightforward to cut and fit with compatible adapters for custom systems.
