Your reliable fuel line fittings supplier

Fuel fittings manufacturer process China

Fuel line fittings are commonly used in fuel tanks, pumps, and other locations to connect hoses and other fuel tank components. These fittings are most commonly available with AN/JIC, and NPT threads, which are tapered threads and therefore require a sealant to stop fluid leakage.

Fuel line fittings are available in stainless steel, aluminum, and brass. Aluminum fittings are lighter, more flexible, and more ductile. In corrosive environments, we recommend stainless steel fuel line fittings.

Fuel fittings are easy to install. Push-in fittings can be pushed directly into the hose and then secured with clamps. The threaded fittings can be screwed directly without the need for any additional tools.

Advantages of Topa fuel hose fittings:

※ Durable

※ Strong seal

※ Wide variety

※ Easy to install
