Legris 3014 56 14 Push-Fit Adapter 1/4 in 290 psi PK10

Product Identity

The Legris 3014 56 14 is a brass push-fit adapter designed for vacuum applications. It connects 1/4 inch outer diameter tubing to a 1/4 inch FNPT threaded port. Supplied in a pack of 10, it suits maintenance engineers and installers who need quick, tool-free connections in pneumatic or fluid systems.

Critical Specification

The defining parameter is the maximum operating pressure of 290 psi. This rating determines whether the fitting matches the system design pressure; exceeding it risks leakage or rupture. The C36000 brass body and 1/4 inch tube size are fixed, so pressure compatibility is the single check before selection.

Sustained Operation Behaviour

Rated for continuous service up to 175 degrees F, the adapter maintains its seal under prolonged thermal and pressure cycling. The push-to-connect mechanism resists vibration loosening better than threaded compression joints. No thread sealant is included, so installers must apply a compatible compound to the FNPT threads to ensure long-term leak-free performance.
