Brass Push-Fit Adapter

This brass push-fit adapter connects a 3/16 inch tube to a 1/8 inch male NPT thread. It uses a push-to-connect design on the tube side for tool-free installation and includes pre-applied thread sealant on the threaded side. The fitting is rated for a maximum operating pressure of 260 psi and a maximum temperature of 155 degrees F.

Vacuum and pneumatic systems

The adapter suits vacuum applications and general pneumatic lines where a compact, straight connection is needed. It is not intended for builders who need an elbow or tee configuration, nor for systems that require a larger tube diameter or a different thread standard.

260 psi pressure rating

The maximum operating pressure of 260 psi determines whether this fitting matches the system design. Verify that the working pressure of the circuit stays within this limit before selecting the part.

Questions about this item

What thread size does the MNPT end of the Legris 3175 55 11 adapter use?

The MNPT end uses a 1/8 in pipe thread, so a matching female 1/8 NPT port or fitting is required for connection.

Will the 3/16 in push-to-connect side accept 1/4 in tubing?

No, the push-to-connect side is sized for 3/16 in outer-diameter tube only; 1/4 in tubing will not seal properly.

How can I confirm the fitting is holding pressure after installation?

Pressurise the line up to 260 psi at no more than 155 °F and check for leaks; the pre-applied thread sealant on the MNPT side should prevent seepage.
