Push-Fit Brass Adapter for 3/8 in Tube

The Legris 3675 60 14 is a nickel-plated brass push-fit adapter designed for lubrication systems. It connects a 3/8 inch outer diameter tube to a 1/4 inch MNPT male thread. The fitting uses a push-to-connect design on the tube side for tool-free assembly. It suits maintenance engineers and installers needing a compact, corrosion-resistant transition between tubing and threaded ports.

C36000 Brass Body with 435 psi Rating

The body uses material grade C36000 brass with a silver nickel-plated finish for durability in fluid handling. Rated for a maximum operating pressure of 435 psi and a maximum temperature of 302 degrees F, it handles demanding lubrication circuits. The 15/16 inch overall length keeps the profile short inside tight enclosures. No pre-applied thread sealant is included, so installers must apply their preferred sealing method to the MNPT threads.

3/8 in Tube to 1/4 in MNPT Transition

This specific adapter bridges a 3/8 inch push-fit tube connection to a 1/4 inch male NPT thread in a single component. It eliminates the need for separate fittings and reduces potential leak paths in the line. It is not suited for applications requiring a different tube diameter, a female thread, or a built-in valve function. Buyers needing other port sizes or end configurations must select a different model.

Questions about this item

What pressure does the 1/4 in MNPT thread handle in practice?

The brass push-fit adapter is rated for a maximum operating pressure of 435 psi, so the 1/4 in MNPT connection will hold up to that limit when installed correctly.

What clearance does the 15/16 in overall length need to fit?

The fitting measures 15/16 in long, so allow at least that much straight run plus room for the 3/8 in tube to insert fully into the push-to-connect side.

How is the fitting installed, and what step is often missed?

Push the 3/8 in tube into the push-to-connect end until it seats, then thread the 1/4 in MNPT side into the port; the step often missed is not applying additional thread sealant because none is pre-applied.
