Push-Fit Adapter for 1/8 in Tubing

The Legris 3175 53 11 is a brass push-to-connect adapter that joins 1/8 in OD tube to a 1/8 in MNPT thread. It carries a maximum operating pressure of 290 psi and a maximum temperature of 175 degrees F. Pre-applied thread sealant is included on the threaded end. The pack contains ten fittings.

Suits vacuum lines and low-pressure plumbing

Installers who need a quick, tool-free connection on 1/8 in tubing will find this adapter convenient. The push-fit design speeds assembly in tight spaces. It is not intended for systems that exceed 290 psi or 175 degrees F, nor for applications requiring a different tube diameter or thread type. Buyers needing other sizes or pressure ratings should look at alternative fittings.

290 psi maximum operating pressure

This single rating defines the safe pressure envelope for the fitting. Brass construction with C36000 grade material supports the stated limit. Always verify that the system design pressure stays at or below 290 psi before installation.

Questions about this item

What tube size must I already have to use the 1/8 in push-to-connect side?

You need tubing with a 1/8 in outer diameter for the push-to-connect end to seal properly.

Will the 1/8 in MNPT thread mate with my existing 1/8 in NPT fittings?

Yes, the Side B connection is a 1/8 in MNPT thread that fits standard 1/8 in NPT female ports.

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

Pressurise the system up to 290 psi and check for leaks; the pre-applied sealant on the MNPT threads and the push-to-connect grip should hold without weeping.
