HAM-LET Compression Fitting Union: 1/4 in OD x 4 mm OD Fitting Size

A HAM-LET compression fitting union connects two tubes of different sizes — 1/4 in OD and 4 mm OD — in industrial tubing systems. Its double-ferrule stainless steel design provides leak-tight, vibration-resistant joints in instrumentation, chemical, and pneumatic applications where reliable fluid or gas handling is critical.

This HAM-LET union is a compression x compression double-ferrule stainless steel fitting. It accommodates 1/4 in OD on one side and 4 mm OD on the other. The MPN is 763L-SS-4MM X 1/4, and it is compatible with Let-Lok fitting brands for secure tubing connections.

3G Electric supplies HAM-LET compression fittings like the 763L-SS-4MM X 1/4 union to customers worldwide. As a global industrial sourcing partner, we handle full logistics and customs clearance to deliver genuine components to your facility, regardless of location.

To install a HAM-LET double-ferrule union, insert the tube fully into the fitting, hand-tighten the nut, then use a wrench to tighten 1-1/4 turns past hand-tight for 1/4 in OD tubing. Always follow manufacturer torque guidelines and inspect ferrules for proper bite before pressurizing the system.
