  • Multi-plane swivel enables flexible fuel hose routing

  • 3/4 in FNPT inlet threads onto standard pump fittings
  • Aluminium, brass and Viton wetted parts resist fuel corrosion

Dayton 33NT03 Swivel Valve

The Dayton 33NT03 is a multi-plane swivel valve constructed from aluminium with brass and Viton wetted parts. It accepts biodiesel, diesel, gasoline and kerosene at a maximum operating pressure of 50 psi. Inlet and outlet connections are 3/4 inch FNPT and NPT respectively.

Suited for fuel-dispensing lines needing rotation

Installers who require a swivel joint for fuel nozzles on biodiesel, diesel, gasoline or kerosene systems will find the pressure rating and connection sizes appropriate. Those needing higher pressure ratings, different thread standards or media compatibility outside the listed fuels should look at alternative valve types.

Simple threaded installation with sealant

The FNPT inlet and NPT outlet thread directly into existing piping using standard pipe sealant. Over-tightening aluminium threads can cause cracking, and using the swivel beyond the 50 psi limit risks seal failure. Confirm media compatibility before pressurising the line.

Questions about this item

Does my fuel nozzle need a 3/4 in FNPT inlet to accept this swivel?

Yes, the swivel has a 3/4 in FNPT inlet and a 3/4 in NPT outlet, so the nozzle or hose must provide a matching male NPT thread.

Will the aluminium, brass and Viton wetted parts resist the diesel and gasoline already in my system?

Those materials are listed as compatible with biodiesel, diesel, gasoline and kerosene, so they suit the fuels you are using.

How can I confirm the swivel rotates freely after installation?

Pressurise the line up to 50 psi and check that the multi-plane joint turns smoothly without binding or leaks.
