Proflow’s 420 Series industrial styled rubber hose is available in black only and is designed to be used with E85, diesel, methanol, coolant, oil, air and transmission fluid. Its outside layer is constructed from a wrapped chlorinated polyethylene which allows it to be used in applications of up to 270 PSI and has a better temperature resistance compared to our traditional 400 Series hose. To ensure a perfect fit, use Proflow 400 & 510 Series fittings and adaptors. Not suitable for submersible applications. Note: Hose clamps must be used on all applications above working pressures of 55 PSI and temperatures above 65°C. Due to the use of unknown additives in some fuel blends, we cannot guarantee our rubber hose’s compatibility with all fuels unless otherwise stated. Please use Proflow’s 200 Series PTFE hose for all other types of fuel.
