Product Description

The HAM-LET Compression Fitting Plug is a double-ferrule stainless steel fitting in the Let-Lok series, sized for 3/4 in OD tubing (MPN 7121L SS 3/4). It is compatible with Swagelok systems, providing a reliable seal in industrial fluid-handling applications.

Frequently Asked Questions

What is a HAM-LET compression fitting plug used for?

A HAM-LET compression fitting plug seals the end of a tubing run in industrial fluid-handling systems. It is used across machining, instrumentation, and process control applications to prevent leakage and maintain system integrity.

What are the specifications of the HAM-LET 7121L SS 3/4?

The HAM-LET 7121L SS 3/4 is a double-ferrule stainless steel compression plug from the Let-Lok series. It fits 3/4 in OD tubing and is compatible with Swagelok systems, providing a reliable seal in high-pressure fluid lines.

Where to buy HAM-LET compression fittings worldwide?

3G Electric supplies HAM-LET compression fittings worldwide. We handle full logistics and customs clearance to deliver the 7121L SS 3/4 plug and other Let-Lok series components to your facility, regardless of location.

How to install a HAM-LET double-ferrule compression plug?

Insert the tubing fully into the fitting, then tighten the nut finger-tight. Use a wrench to turn the nut 1-1/4 turns past finger-tight for proper ferrule swaging. Always follow the manufacturer's torque specifications for leak-free performance.
