Amerimax Home Products 55020 Female Coupler 4 in Black

Product Description

The AMERIMAX HOME PRODUCTS 55020 is a 4-inch black female coupler designed for joining two pieces of cut plastic corrugated pipe. It also adapts flex drain pipe to compatible wyes and tees, improving the fit and function of the overall drainage system. This coupler is a common component in residential and light commercial drainage installations where corrugated pipe sections need to be connected cleanly and securely. Plumbers, drainage contractors, and experienced DIYers install this fitting as part of underground or above-grade flex drain pipe runs.

This coupler is used wherever 4-inch corrugated plastic drain pipe sections meet — including foundation drainage, yard drainage, and downspout drain line installations. It is suited for connecting cut pipe ends that require a reliable female-type coupling to maintain flow continuity through the system. When used alongside wyes and tees, it helps ensure consistent fitment at transitions and junction points in the drainage line.

Installation Notes

Installation is typically performed by plumbers or drainage contractors working on residential or light commercial drain pipe systems. Ensure the corrugated pipe ends are cleanly cut before inserting into the female coupler to achieve a proper seal and fit. No special tools are required, but confirming pipe diameter compatibility before installation is recommended. Follow all applicable local plumbing codes for underground drainage installations.
