14 mm push-fit elbow for vacuum lines

The Legris 3109 14 21 is a black fiberglass-reinforced nylon fitting that joins 14 mm tubing to a 1/2 inch male BSPT port. It is supplied as a pack of 10 pieces for pneumatic or vacuum circuits.

Check tube diameter and thread standard

Verify that your existing line uses 14 mm outer-diameter tubing and that the receiving port accepts a 1/2 inch male BSPT thread. The fitting handles up to 290 psi and 175 degrees F, so confirm your system stays within those limits.

Pre-applied sealant speeds assembly

Each elbow arrives with thread sealant already on the male end, removing the need for tape or paste during installation. The push-to-connect side grips the tube without tools, cutting fitting time on vacuum or low-pressure pneumatic work.

Questions about this item

What comes in the pack and do I need extra sealant or tools?

The pack contains ten push-fit elbow fittings with pre-applied thread sealant already on the threads, so no separate sealant is required; only a tube cutter or deburring tool for the 14 mm tube is needed.

How do I choose between the 14 mm tube and 1/2 in pipe versions listed?

This single model joins a 14 mm outer-diameter tube on the push-to-connect side to a 1/2 in MBSPT threaded pipe on the other; there is no separate version to select.

What does the 290 psi rating mean when the fitting is installed in a vacuum line?

The 290 psi maximum operating pressure is the limit for positive pressure; in vacuum service the fitting is rated for full vacuum at up to 175 °F, so it will hold vacuum without leaking within that temperature range.
