- These Hoses are designed to perform in both diesel and bio-diesel fuel mixtures
- These Hoses are intended for use as fuel feed and return hose in applications where high-temperature diesel or biodiesel fuel is being circulated through the diesel fuel delivery system of on-demand and recirculating type found in mobile, stationary, and marine applications. This hose has a maximum working pressure of 0.34 MPa (50 psi).
- The Hoses are suitable for use in a normal external operating temperature range from –50°C to 180 °C, and normal internal operating temperature range from –25°C to 80°C.
- The Inner Liner of the Hose is made with a 2mm thick oil-resistant (and bio-diesel resistant) liner, and the Outer Cover is made in Silicone material (any colour of your choice), of 2-3mm thickness.
