Push-Fit Elbow for 12 mm Tube

This Legris 3109 fitting joins 12 mm tubing to a 1/2 inch male NPT thread at a 90-degree angle. The body is moulded from fiberglass-reinforced nylon and includes pre-applied thread sealant. It is rated for 290 psi and 175 degrees Fahrenheit. The push-to-connect design allows tool-free tube insertion on the tube side.

Suits vacuum lines needing a right-angle transition

Installers who require a compact elbow between metric tubing and imperial pipe threads will find this part suitable. Systems that demand metal construction, higher temperature ratings, or a different thread standard should select an alternative fitting. The black colour coding helps identify the line in mixed installations.

12 mm push-to-connect to 1/2 inch MNPT

The critical specification is the combination of a 12 mm tube outer diameter on side A and a 1/2 inch male NPT thread on side B. Verify both dimensions against your tubing and port before ordering. The maximum operating pressure of 290 psi and temperature of 175 degrees F define the safe operating envelope.

Questions about this item

Will the pre-applied thread sealant on the 1/2 in MNPT side need re-application after the first installation?

The fitting includes pre-applied thread sealant intended for the initial installation; if the joint is disassembled later, fresh sealant or tape should be applied before reassembly.

At 290 psi maximum operating pressure, which component is most likely to reach its limit first during sustained high-pressure use?

The fiberglass-reinforced nylon body and the push-to-connect collet on the 12 mm tube side define the 290 psi pressure ceiling; sustained operation at that pressure will stress those elements first.

How much heat does the fitting itself generate when fluid runs continuously at the 175 °F maximum operating temperature?

The fitting does not generate heat; it simply conducts the fluid temperature, so at 175 °F the nylon body will equilibrate to that temperature without adding any thermal load of its own.
