Push-Fit Elbow for Vacuum Lines

The Legris 3129 08 14 is a push-fit elbow fitting designed for vacuum applications. It connects 5/16 inch outer-diameter tubing to a 1/4 inch male NPT thread. The body is moulded from black fiberglass-reinforced nylon. A pack contains ten pieces.

Thermals Noise and Power Draw

The fitting is rated for a maximum operating temperature of 175 degrees Fahrenheit. It withstands pressures up to 290 psi in normal service. Pre-applied thread sealant on the NPT side helps create a leak-free seal without extra compounds. There are no moving parts to generate noise or consume power.

5/16 Inch Tube to 1/4 NPT Interface

The single specification that decides fitment is the combination of a 5/16 inch push-to-connect port and a 1/4 inch male NPT thread. Systems using different tube diameters or thread standards cannot use this elbow. Buyers who need a straight connector or a different thread size must select another part.

Questions about this item

How do I install the 3129 08 14 elbow, and what step causes leaks?

Thread the 1/4 NPT male end into the port with the pre-applied sealant; do not add tape or paste. Push the 5/16 in tube fully into the push-to-connect side until it seats, then pull back to verify the collet grips.

What maintenance or replacement will the 3129 08 14 need over time?

Inspect the fiberglass-reinforced nylon body and collet for cracks or stress whitening. Replace the fitting if the tube no longer locks securely or if the pre-applied thread sealant shows signs of weeping after thermal cycles.

Which limit appears first when the 3129 08 14 runs continuously at pressure?

The 290 psi maximum operating pressure is the primary limit; sustained pressure at or above this value will cause fitting deformation before the 175 Degrees F temperature rating becomes critical.
