Push-Fit Elbow for Vacuum Lines

This Legris 3109 fitting connects a 5/16 inch tube to a 1/8 NPT male thread using a push-to-connect design. The fiberglass-reinforced nylon body ships in a pack of 10 pieces. Pre-applied thread sealant removes the need for separate tape or paste during installation. It suits pneumatic and vacuum circuits in automotive or industrial settings.

Thermals, Noise and Power Draw

The fitting contains no moving parts, so it produces no noise and draws no power. Its nylon construction handles continuous service up to 175 degrees Fahrenheit. The maximum operating pressure is rated at 290 psi, providing a wide margin for typical vacuum and low-pressure air lines. No fan, pump or electrical supply is involved.

Upgrade Path and Compatibility

This elbow replaces threaded compression or barbed fittings where a quick-release push-fit joint speeds assembly and service. The jump is worth it when technicians need tool-free tube insertion and reliable sealing without re-taping threads. Builders who require metal bodies, higher temperature ratings or different thread standards must select alternative components.

Questions about this item

How do I install the Legris 3109 08 11 push-fit elbow onto 5/16 in OD tubing and a 1/8 NPT port?

Cut the tube square, push it fully into the push-to-connect end until it seats, then thread the 1/8 NPT male side into the port; the pre-applied thread sealant removes the need for tape or paste.

What maintenance or replacement will this fitting need over time?

Inspect the push-to-connect grip ring and O-ring periodically for wear or contamination; replace the entire fitting if the tube no longer locks securely or if leaks appear at either connection.

What is the first limit reached under sustained pressure and temperature?

The maximum operating pressure of 290 psi is the primary design limit; sustained exposure above this or above the 175 °F temperature rating will degrade the fiberglass-reinforced nylon body and seals.
