Brass Push-Fit Adapter for 3/16 in Tube

This brass push-fit adapter connects a 3/16 in outer-diameter tube to a 1/4 in male NPT thread. It is rated for 260 psi maximum operating pressure and 155 degrees F maximum temperature. The fitting uses a C36000 brass body and includes pre-applied thread sealant. Supplied in a pack of ten.

Suits Vacuum Lines and Small-Bore Pneumatics

The adapter is designed for vacuum and low-pressure pneumatic circuits using 3/16 in tubing. It will not suit applications requiring larger tube sizes, female-thread connections or higher temperature ratings beyond 155 degrees F. Builders needing different thread types or tube diameters should select an alternative fitting.

3/16 in Push-to-Connect to 1/4 MNPT Interface

The decisive specification is the combination of a 3/16 in push-to-connect port and a 1/4 in male NPT thread. This exact interface determines whether the adapter matches the tubing and port in the system. Verify both dimensions before ordering.

Questions about this item

Does the pack of 10 Legris 3175 55 14 adapters include any extra tools or seals?

Each brass adapter comes with pre-applied thread sealant on the 1/4 in MNPT side; the 3/16 in push-to-connect end needs no separate ferrule or tool, so nothing else is required.

Should I choose the 3/16 in OD version or a different tube size for my vacuum line?

Select this 3/16 in OD model only when your tubing matches that exact outside diameter; other tube sizes need their own matching Legris push-fit part number.

Will the 260 psi rating hold when the fitting is installed on a hot engine bay line?

The brass body and C36000 grade are rated to 260 psi up to 155 °F; above that temperature the pressure limit drops, so verify your maximum line temperature before installing.
