Push-Fit Elbow for Vacuum Lines

The Legris 3109 62 21 is a black push-fit elbow fitting designed for vacuum applications. It connects a 1/2 in tube on the push-to-connect side to a 1/2 in male BSPT pipe thread on the other. The body is moulded from fibre-glass-reinforced nylon and comes in a pack of 10 pieces.

Sustained Pressure and Temperature Behaviour

The fitting carries a maximum operating pressure of 290 psi and a maximum operating temperature of 175 Degrees F. Under continuous vacuum or pressure cycling the reinforced nylon body resists creep and the pre-applied thread sealant maintains its bond without re-taping. Performance stays consistent up to the rated limits.

Installation Notes and Common Pitfalls

Push the tube firmly until it seats; the collet grips automatically and the internal O-ring seals. Thread the MBSPT end into the port by hand then tighten — no extra sealant is required because it is already coated. The main error is insufficient tube insertion or cross-threading the tapered pipe thread during initial engagement.

Questions about this item

Does the 290 psi rating hold when the fitting runs continuously at 175 Degrees F?

Yes, the 290 psi maximum operating pressure and 175 Degrees F maximum operating temperature are both rated for continuous service.

What thread sealant or tape do I need for the 1/2 in MBSPT end?

None — the 1/2 in MBSPT side already has pre-applied thread sealant included.

Will this 1/2 in push-to-connect elbow accept my existing 1/2 in nylon tubing?

Yes, the push-to-connect side is sized for 1/2 in tube outer diameter, matching standard 1/2 in nylon tubing.
