Push-fit elbow for 1/8 in tube

This push-fit elbow connects 1/8 inch outer-diameter tubing to a 1/4 inch male NPT thread. It is made from black fiberglass-reinforced nylon and rated for 290 psi at 175 degrees F. Pre-applied thread sealant is included on the threaded end. The pack contains ten fittings.

Suits pneumatic and vacuum lines needing

Installers who need a compact right-angle connection between 1/8 in push-to-connect tubing and 1/4 in NPT ports will find this fitting suitable. It is not for systems requiring metal bodies, higher temperature ratings or different tube or thread sizes.

1/8 in push-to-connect to 1/4 in MNPT

The defining specification is the combination of a 1/8 inch push-to-connect port on one side and a 1/4 inch male NPT thread on the other. This exact interface match determines whether the elbow fits the intended tubing and port.

Questions about this item

How does the push-to-connect interface on this 1/8 in OD elbow handle vacuum applications?

The push-to-connect end seals on the 1/8 in tube outer diameter and is rated for vacuum service up to the 290 psi maximum operating pressure.

What clearance and thread engagement does the 1/4 in MNPT end need to mount properly?

The male NPT thread requires a standard 1/4 in female NPT port; the pre-applied sealant coats the threads so no tape is needed.

What is the correct installation sequence to avoid a leak at the push-fit side?

Cut the 1/8 in tube square, deburr it, then push it straight in until the collet grips and the tube bottoms out against the internal stop.
