1/8 in Push-Fit Elbow Fitting

This Legris 3129 53 11 fitting joins 1/8 in tube to a 1/8 in male NPT thread at a 90-degree angle. The push-to-connect design secures the tube without tools. Fiberglass-reinforced nylon construction handles vacuum service up to 290 psi and 175 Degrees F. Pre-applied thread sealant is included on the threaded end.

Suits pneumatic and vacuum lines needing a compact

Installers who prefer compression or flare connections will need a different fitting style. Systems requiring metal threads or higher temperature ratings should look elsewhere. The fixed 1/8 in tube and thread sizes cannot be adapted to other diameters.

Push-to-connect on 1/8 in tube OD

The single decisive specification is the 1/8 in tube outer diameter matched to a 1/8 in male NPT thread. If your line uses a different tube size or thread standard, this fitting will not seal. Verify both dimensions before ordering.

Questions about this item

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

The push-to-connect side accepts 1/8 in outer-diameter tubing, so that exact tube size must be on hand before installation.

Will the 1/8 in male NPT threads mate with my existing galvanised fittings?

Yes, the B side uses 1/8 in male NPT threads, which match standard galvanised or brass fittings of the same thread size.

How do I confirm the pre-applied sealant is holding at 290 psi after I tighten the fitting?

Pressurise the line to its working pressure and watch for bubbles or pressure drop; a stable reading at 290 psi shows the sealant is functioning.
