The Rainmaid Poly-Stretch Coupling is a molded plastic repair fitting designed for polyethylene sprinkler pipes. Engineered to expand and form a watertight seal in place, it lets you fix leaking lines without manipulating or bending the pipe, reducing the risk of further damage. Ideal for irrigation systems, this coupling provides a clean, reliable repair that holds under typical outdoor conditions.

Designed for polyethylene sprinkler pipe: Specifically made to join and repair PE irrigation tubing without additional adapters.
Expanding poly-stretch design: The coupling stretches to accommodate the line, creating a secure, leak-resistant seal in any position.
Durable molded plastic construction: Resistant to corrosion and abrasion for long service life in outdoor environments.
Simple installation: No special tools required—position, expand, and seat the fitting for an immediate repair.
Available sizes: Offered in 3/4 in (PSC-07) and 1 in (PSC-10) to match common irrigation tubing diameters.
Low-maintenance solution: Designed for irrigation use where long-lasting, dependable repairs are needed.

Each coupling is sold individually (select the required size from the variant options). Use the coupling to repair small leaks and breaks in polyethylene sprinkler lines with minimal disruption. For best results, confirm pipe diameter before purchase and follow standard irrigation repair practices during installation. If you need assistance choosing the correct size, check the tube outside diameter or consult a local irrigation professional.
