Male Elbow Fitting 12 mm 3/8 in

This Legris 3109 push-fit elbow connects a 12 mm tube to a 3/8 inch male BSPT thread. The body is moulded from black fiberglass-reinforced nylon and ships in a pack of ten. Pre-applied thread sealant is included on the threaded end for faster assembly. It is rated for vacuum service and general fluid handling.

Suits pneumatic and vacuum lines

Installers who need a compact 90-degree transition from metric tubing to a 3/8 inch male port will find this fitting convenient. The push-to-connect end requires no tools, while the sealed thread reduces leak risk. Buyers needing a straight connector, a female thread, or a different tube diameter should select an alternative part.

Maximum pressure 290 psi at 175 °F

The fitting withstands up to 290 psi at a maximum operating temperature of 175 degrees Fahrenheit. This pressure and temperature envelope defines the safe operating window for compressed-air, vacuum or compatible fluid systems. Verify that your application stays within these limits before installation.

Questions about this item

What tube and thread sizes does the 12 mm push-fit elbow accept?

Side A takes a 12 mm outer-diameter tube; Side B is a 3/8 in MBSPT male thread.

How is the pre-applied sealant used during installation, and what mistake should be avoided?

Screw the 3/8 in male thread into the port by hand until the sealant contacts the face, then tighten one to two turns — do not apply extra tape or paste.

When should the fiberglass-reinforced nylon fitting be replaced under normal vacuum service?

Replace if the body shows cracking, the push-to-connect collet no longer grips the 12 mm tube, or the sealant on the 3/8 in thread is damaged.
