Legris 3109 53 10 Push-Fit Elbow Fitting 1/8 in

Application and Suitability

This push-fit elbow fitting connects 1/8 inch tubing to a 1/8 inch male BSPT thread using a push-to-connect design. It is intended for vacuum applications and suits installers who need a quick, tool-free joint in pneumatic or low-pressure fluid systems. The fiberglass-reinforced nylon body and pre-applied thread sealant simplify assembly without separate tape or paste. It is not for buyers who need a straight connector, a different thread standard, or a metal-bodied fitting for higher mechanical loads.

Sustained Load Behaviour

The fitting is rated for a maximum operating pressure of 290 psi and a maximum operating temperature of 175 degrees Fahrenheit. Under continuous vacuum or pressure within these limits the reinforced nylon construction resists creep and maintains seal integrity over time. The pre-applied sealant remains effective through repeated thermal cycles without requiring re-tightening. It is not for systems that exceed the stated pressure or temperature envelope or that demand all-metal construction for fire-rated environments.

Interface Practical Limits

The push-to-connect end accepts only 1/8 inch outer-diameter tubing, while the threaded end matches 1/8 inch male BSPT ports. No other tube sizes or thread forms are compatible without adapters, which are not included. The 290 psi and 175 degrees Fahrenheit ratings define the safe operating window for the combined interface; operating beyond either limit risks leakage or fitting failure. It is not for installations requiring larger flow passages, different thread pitches, or compatibility with imperial NPT threads.
