Bk 160-203HC Cpvc Compression Coupling 5/8 in Od X 1/2 in

Product Description

The BK 160-203HC is a CPVC compression coupling designed to join or repair tubing in residential hot and cold water supply lines. The fitting connects 5/8 inch OD tubing using a 1/2 inch compression end, creating a leak-resistant joint without solvent cementing or open flame. At 5 inches in length and weighing 0.133 pounds, it is a compact, lightweight fitting suited for tight spaces in plumbing rough-in and repair work. Licensed plumbers and experienced DIYers install this type of fitting when restoring water line continuity after a break or when extending existing runs.

This coupling is used in residential plumbing systems where CPVC tubing carries potable hot or cold water. Typical install scenarios include repairing damaged tubing sections, coupling mismatched cut ends, or completing short extensions in supply line runs. The compression design makes it practical in retrofit and repair situations where access is limited and a tool-free joint is preferred. It is sold individually, making it easy to order for single-point repairs.

Installation Notes

Installation should be performed by a licensed plumber or qualified tradesperson in accordance with local plumbing codes and IPC guidelines. Shut off the water supply and relieve line pressure completely before cutting or removing existing tubing. Ensure tubing ends are cut square and deburred before seating into the compression fitting. Do not overtighten compression nuts, as CPVC is susceptible to cracking under excessive mechanical stress.
