Male Elbow Trap 8mm 3/8in PK10

This Legris push-fit elbow fitting connects an 8mm tube to a 3/8 inch male BSPT thread in vacuum applications. The fiberglass-reinforced nylon body resists corrosion and handles demanding fluid or air lines. Supplied as a pack of ten pieces for production or maintenance use. Suitable for installers needing quick, tool-free assembly.

Maximum operating pressure 290 psi

The fitting is rated for a maximum operating pressure of 290 psi, making it the decisive figure for system compatibility. Verify that your vacuum or pressure circuit never exceeds this limit before installation. Exceeding the rating risks leakage or fitting failure under load. No higher pressure rating is claimed.

Pre-applied thread sealant included

Each elbow arrives with thread sealant already applied to the male BSPT side, removing the need for separate tape or paste. This reduces assembly time and eliminates a common source of leaks caused by uneven manual sealing. The push-to-connect tube end requires no tools or additional sealant. Ready for immediate installation.

Questions about this item

How does the 290 psi pressure rating hold up when the fitting is installed in a live pneumatic line?

The 290 psi maximum operating pressure is the design limit for the push-fit elbow; in a real machine the joint will seal at that pressure provided the tube is cut square, fully inserted and the system does not exceed the rating.

What does the MBSPT 3/8 in thread actually seal against and what torque should I use?

Side B is a 3/8 in MBSPT taper thread with pre-applied sealant; it seals on the thread flanks when screwed into a matching female BSPT port, and hand-tight plus one to two turns is normally sufficient — do not over-torque the nylon body.

Will the 8 mm push-to-connect end accept standard 8 mm nylon or polyurethane tubing without leaks?

Yes, the Side A port is sized for 8 mm (5/16 in) outer-diameter tubing; push the tube in until it bottoms out and the collet locks, giving a seal rated to the 290 psi / 175 °F limits.
