Elkhart Products COU-34 Copper Coupling with Stop 3/4 in

Product Description

The ELKHART PRODUCTS COU-34 is a 3/4-inch copper coupling with stop, part of the KLEENFIT product line and built for soldered sweat connections in residential and light commercial plumbing systems. Rated for C x C (copper-to-copper) sweat joining, this coupling features an internal stop that ensures consistent pipe seating depth before soldering, improving joint quality and reducing callback risk. At 0.560 pounds and measuring approximately 0.97 inches by 1.59 inches by 0.97 inches, it is a compact, purpose-built fitting sized for standard 3/4-inch copper pipe runs. KLEENFIT fittings are pre-cleaned and bagged to maintain interior cleanliness until installation.

This coupling is used in potable water supply lines, hydronic heating distribution, and general copper pipe repair or extension work. The with-stop design makes it well suited for straight-run connections where pipe depth control is critical to a sound solder joint. It is installed by licensed plumbers and qualified pipefitters working with Type L or Type M copper tubing in residential and light commercial construction or service applications.
