The HARCO 75-10833 is a compression-by-compression coupling with an integrated stop, designed for joining two sections of pipe in plumbing distribution systems. The built-in stop positions pipe ends consistently, ensuring a repeatable, leak-resistant seal without soldering or threading. This fitting is installed by licensed plumbers and experienced tradespeople working on water supply lines in residential and light commercial applications.
This coupling is suited for use in water supply piping applications where a compression fitting connection is preferred or required. Compression fittings are commonly used in retrofit and repair scenarios where heat cannot be applied, or where quick, reliable connections are needed without specialized tooling beyond a wrench.
Designed as an OEM-style replacement fitting for residential and light commercial water supply plumbing systems using compression-type connections.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve line pressure before beginning work. Ensure pipe ends are cut cleanly and deburred before seating into the compression fitting. Do not overtighten compression nuts, as this can deform the ferrule and compromise the seal.
