Push-fit elbow for 5/16" tube

This Legris 3109 fitting joins a 5/16 inch tube to a 1/4 inch MBSPT port at a 90 degree angle. The push-to-connect end accepts metric 8 mm or imperial 5/16 inch outer diameter tubing without tools. Pre-applied thread sealant on the male side speeds installation in vacuum or pressure lines. It suits maintenance engineers and OEM assemblers who need a compact, releasable corner joint.

Pressure headroom to 290 psi and 175 °F

The fiberglass-reinforced nylon body withstands continuous service up to 290 psi and 175 degrees Fahrenheit. That envelope covers most shop-air, pneumatic automation and vacuum circuits. Systems running above 290 psi or hotter than 175 °F will exceed the rating and need a different fitting. The material also resists common oils and coolants found in industrial environments.

Black composite body with pre-sealed male thread

The black HAWA composite construction is lighter than brass and does not corrode in humid plants. The 1/4 inch MBSPT male thread seals on installation without extra tape or paste. Push-to-connect release collet allows tube removal for rework or module swap. No mounting hardware is included; the fitting secures itself through the threaded port and tube grip.

Questions about this item

Will the 5/16 inch push-to-connect side fit the 8 mm nylon tubing I already use?

The 5/16 inch tube outer diameter matches common 8 mm metric tubing, so the push-to-connect end should accept your existing line.

How can I confirm the pre-applied thread sealant on the 1/4 inch MBSPT side is sealing correctly after installation?

Pressurise the system up to 290 psi and check for leaks at the threaded joint; no seepage means the sealant is working.

Does the box include the 1/4 inch MBSPT mating adapter or must I buy it separately?

Only the 3109 elbow fitting with pre-applied thread sealant is supplied; any mating adapter or tubing must be purchased separately.
