Product Overview

System shutdowns during the height of the summer heat cause immediate turf stress and jeopardize project deadlines. When a mainline or lateral pipe fractures, every hour of downtime increases the risk of crop loss or dry spots that lead to client complaints. Supply chain instabilities and seasonal back orders often mean the difference between a quick repair and a costly delay. Planning ahead by stocking reliable repair fittings ensures your crews are ready to respond to emergencies instantly, keeping your schedules intact and your clients satisfied through the peak of the irrigation season.

The Lesso Schedule 40 Compression Coupling offers a distinct technical advantage over traditional solvent weld repairs in wet or restricted conditions. Because it uses a high grade gasketed seal instead of primer and glue, your installers can perform repairs in active trenches without waiting for the pipe to dry or the cement to cure. This reduces labor costs by shortening the time spent on each service call. Maintaining a stock of these professional grade fittings provides a competitive edge, allowing your team to complete more repairs per day while ensuring a durable, leak proof connection that stands up to standard system pressures.

• Dual compression nuts allow for slight pipe misalignment during difficult trench repairs.
• Compression design serves as an expansion joint to absorb thermal movement in the pipe.
• Wide internal gaskets provide a broad sealing surface to prevent leaks on weathered pipe.
• Quick assembly design reduces the footprint required for repair excavations and saves labor.

Common Applications

• Commercial landscape irrigation

Installation Notes

Ensure the pipe ends are cut square and deburred to prevent damaging the internal gaskets during insertion. Slide the compression nuts onto the pipe ends followed by the gaskets before inserting the pipe into the coupling body. Tighten the nuts firmly by hand and apply a final quarter turn with a pipe wrench or strap wrench to ensure a secure seal. Always follow local plumbing codes and verify that the system is pressure tested before backfilling the trench.
