Fuel Transfer Hose

This Dayton 12F731 hose is built for transferring fuel in automotive and industrial settings. It suits technicians and maintenance crews who need a 12-foot reach with 3/4-inch NPT ends on both sides. The nitrile tube handles common petroleum-based fluids within the rated pressure and temperature limits.

Zinc NPT Fittings

Both ends carry 3/4-inch NPT fittings made from zinc, so the hose threads directly onto matching ports without extra adapters. The rubber cover resists abrasion while the anti-static construction helps dissipate static charge during fuel flow. No clamps or sealant are included in the package.

50 psi Working Pressure

The maximum working pressure is 50 psi at 70 degrees Fahrenheit, which decides whether this hose fits a given fuel system. It operates from -22 to 130 degrees Fahrenheit and is not compatible with diesel exhaust fluid. Buyers needing higher pressure or DEF service must select a different specification.

Questions about this item

How often should the nitrile tube on this 12 ft fuel hose be inspected for wear?

Inspect the nitrile tube visually every few months for cracks, hardening or soft spots, especially near the zinc NPT fittings where flexing is greatest.

What pressure limit will the 50 psi working rating hit first during continuous diesel transfer?

The 50 psi maximum working pressure at 70 °F is the limiting factor; sustained flow above that pressure risks fitting leaks or hose rupture.

How hot does the rubber cover get when fuel runs through it all day in a 130 °F engine bay?

The hose is rated to 130 °F ambient; in a hot engine bay the rubber cover will approach that temperature but should not exceed the rated limit.
