Sch40 UNION W/O-RING SEAL (SOC x SOC)

Product Overview

System shutdowns during the peak of the summer heat can lead to rapid turf desiccation and costly crop loss, placing immense pressure on your maintenance crews to perform fast repairs. When a rigid piping system lacks a mechanical union, a simple valve replacement often requires cutting out large sections of pipe, which leads to extended downtime and increased labor costs. With global supply chains remains unpredictable, waiting until a critical failure occurs to source high quality PVC unions often results in project delays and failed inspections. Planning your inventory ahead of the mid-season rush ensures your team can restore flow immediately, keeping your clients satisfied and your project deadlines intact.

The Lesso Schedule 40 Union provides a distinct technical advantage over permanent solvent weld couplings by allowing for easy disassembly without cutting the pipe. This specific SOC x SOC configuration utilizes a high grade EPDM O-ring seal to ensure a leak proof connection even under varying thermal expansion cycles that often cause standard fittings to weep. By installing these unions at critical points like pump manifolds or backflow assemblies, you significantly reduce future labor requirements for component servicing. Investing in professional grade Lesso fittings provides your business with a competitive edge by minimizing call backs and ensuring long term system integrity.

Key Features

• True union design allows for quick removal of valves or pumps without cutting into established pipe runs.
• Precision molded socket deepness ensures maximum surface area for solvent welding and a secure bond.
• Heavy duty EPDM O-ring provides a superior watertight seal compared to union designs that rely on plastic to plastic contact.
• Knurled nut design allows for hand tightening or easy grip with a pipe wrench in tight irrigation boxes.
• Manufactured from UV resistant PVC to prevent embrittlement when installed in outdoor or exposed environments.
• Consistent wall thickness meets ASTM D2466 standards for reliable performance under standard irrigation pressures.

Common Applications

• Commercial landscape irrigation
• Residential lawn and garden systems
• Sports turf and golf course maintenance
• Municipal parks and public spaces
• Greenhouse and nursery operations
• Pool/spa/water feature plumbing

Installation Notes

For a secure installation, ensure both pipe ends are cut square and deburred before applying a high quality PVC primer and solvent cement. The union should be disassembled during the solvent welding process to prevent excess glue from seizing the nut or damaging the O-ring seal. Once the solvent has cured, inspect the O-ring for any debris, apply a silicone based lubricant if necessary, and tighten the nut firmly by hand. Avoid over tightening with heavy tools as this can stress the plastic threads, and always verify locally applicable plumbing codes for use in pressurized lines.
