Description

The Mosmatic 90.033 Check Valve is a brass one-way valve designed for medium to high-pressure systems up to 4000 psi. Its 3/8" NPTF inlet and 1/4" NPTF outlet allow smooth integration in setups that require different thread sizes on each end.

Engineered with a hard spring mechanism, it opens at ~14 psi and closes at ~20 psi, helping to prevent reverse flow and maintain system efficiency. Its 2.4" length makes it an excellent solution for compact installations.

Applications:

  • Car wash and spray systems

  • Compressed air and fluid control lines

  • Pressure washers

  • Step-down threaded connections

Features:

  • Solid brass construction

  • Rated up to 4000 psi

  • Mixed NPTF thread sizes (3/8" in, 1/4" out)

  • Internal hard spring for reliable one-way flow

  • Lightweight and corrosion resistant
