Extended Male Elbow 1/8 NPT Pack 10

This Legris push-fit elbow fitting connects a 5/16 inch tube to a 1/8 inch male NPT thread. It is made from black fiberglass-reinforced nylon for durability in plumbing and automotive applications. The pack contains ten fittings suitable for vacuum and fluid transfer systems. Pre-applied thread sealant simplifies installation.

Capacity and Headroom 290 psi 175 Degrees F

The fitting handles a maximum operating pressure of 290 psi and a maximum operating temperature of 175 degrees F. It provides reliable sealing within these limits for standard pneumatic and hydraulic circuits. Performance drops if pressure or temperature exceed the rated values. It is not designed for high-pressure hydraulic systems beyond 290 psi.

Push-to-Connect and MNPT Interface Limits

The push-to-connect end accepts only 5/16 inch outer diameter tubing. The male NPT end fits 1/8 inch female threads exclusively. The pre-applied sealant is single-use; reassembly may require additional sealant. Fiberglass-reinforced nylon resists many chemicals but may degrade with aggressive solvents or UV exposure.

Questions about this item

Will the 5/16 in push-to-connect side of the 3129 08 11 fitting seal onto my existing 5/16 in nylon tubing without leaks?

Yes, the push-to-connect end is made for 5/16 in tube outer diameter and the fiberglass-reinforced nylon body grips and seals on contact.

How can I verify the 1/8 in NPT threads are sealing at the rated 290 psi after installation?

Pressurise the system to working pressure and check the pre-applied thread sealant on the male NPT end for any sign of leakage.

Does the pack of 10 include any extra sealant or tools for the 1/8 in NPT connections?

Each elbow already has thread sealant pre-applied on the male NPT side; no additional sealant or special tools are supplied in the box.
