Midland Industries LF66-1412 Brass Compression Coupling

Product Description

The MIDLAND INDUSTRIES LF66-1412 is a lead-free brass compression coupling designed to connect tubing to female iron pipe (FIP) threaded fittings. The first end accepts a 7/8 inch compression connection using a 1-1/8-18 thread, while the second end is a 3/4 inch FIP connection using a 3/4-14 thread. Constructed from lead-free brass, this coupling meets potable water application requirements and is rated for temperatures from -40 degrees F to 250 degrees F. Plumbers and pipefitters install this fitting where a compression-to-FIP transition is needed in a copper, aluminum, or plastic tubing run.

This coupling is suited for residential and light commercial plumbing, refrigeration, and HVAC applications where a compression fitting must terminate into a female threaded port. It works with copper tubing, aluminum tubing, and plastic tubing, making it a versatile choice for mixed-material installations. The lead-free brass construction makes it appropriate for potable water systems where lead-free compliance is required by local code.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before making or breaking any connections. Hand-tighten the compression nut onto the tubing, then use an appropriately sized wrench to achieve a leak-free seal - do not overtighten, as excessive force can deform the compression sleeve and cause leaks. Verify that local plumbing codes, such as those based on the IPC, recognize the tubing material in use for the intended application.
