Push-Fit Elbow for 1/4 in Tube

This push-fit elbow fitting connects 1/4 in tube to a 1/8 in NPTF thread using bio-based nylon. It is designed for vacuum applications and includes a pre-applied thread sealant for easier installation. The fitting is white and rated for a maximum operating pressure of 230 psi.

Replaces Threaded Compression Fittings

The push-to-connect design removes the need for separate ferrules or wrenches during assembly. This upgrade is worth it when faster installation and tool-free tube release are priorities in vacuum systems. The bio-based nylon material offers a different chemical profile than standard nylon variants.

Suits Vacuum Lines Needing Quick Connects

Installers working with 1/4 in outer diameter tubing and 1/8 in pipe threads will find this elbow matches their specifications. Buyers who need a different tube size, thread type, or higher temperature rating above 200 degrees F should look at alternative fittings.
