Push-Fit Elbow for Vacuum Lines

This Legris 3109 push-fit elbow connects 12 mm tube to a 3/8 NPT male thread. It is built for vacuum applications in automotive and industrial plumbing. The fiberglass-reinforced nylon body is coloured black and rated for 175 Degrees F. A pack contains 10 fittings.

12 mm Tube to 3/8 NPT Transition

The single specification that decides fit is the 12 mm outer-diameter push-to-connect side meeting a 3/8 NPT male thread side. Maximum operating pressure is 290 psi. Pre-applied thread sealant is included on the NPT end. No other tube or thread sizes are covered by this part number.

Tool-Free Tube Insertion, Hand-Tight Thread

Push the 12 mm tube into Side A until it seats; no tools or clamps are needed. Thread Side B into the port by hand, then tighten one to two turns with a wrench — the sealant does the rest. Common errors are cutting the tube unevenly, leaving debris inside, or over-tightening the NPT thread and cracking the nylon body.

Questions about this item

What does the 290 psi pressure rating mean when the fitting is installed in a pneumatic system?

The fitting is rated for a maximum operating pressure of 290 psi, so the connected tubing and air supply must not exceed this limit during use.

How does the 3/8 inch NPT thread affect compatibility with existing pipework?

The male NPT thread mates with standard 3/8 inch female NPT ports; the pre-applied sealant helps create a leak-free joint without extra tape.

What tube size and clearance does the 12 mm push-to-connect end require?

It accepts 12 mm outer-diameter tubing with a simple push-in action; allow enough space around the elbow for the tube to enter straight and for the release collar to be accessed if needed.
