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

Product Overview

System shutdowns during peak summer heat can devastate turf and lead to costly emergency service calls for your crew. When a standard fitting fails or a pump requires maintenance without an accessible disconnect point, the resulting water waste and project delays hurt your reputation. Historically, supply chain interruptions and back-orders on schedule 40 fittings can stall mid-season repairs exactly when your clients are most desperate. By securing these Lesso unions now, you ensure your team can perform localized repairs without cutting out sections of mainlines. Planning ahead with a stocked service truck keeps your projects on schedule and ensures your clients remain satisfied during the high demand of late spring.

The Lesso Schedule 40 Union offers a significant technical advantage over standard couplings by providing a removable connection point that maintains a watertight seal under pressure. This design saves considerable labor and long-term maintenance costs because it allows for the easy removal of pumps, valves, and filters without destructive pipe cutting. The FIPT x FIPT threaded configuration provides a secure, mechanical joint that resists internal pressure surges better than lower-grade alternatives. Maintaining a stock of these unions gives you the competitive edge of being prepared to handle complex manifold repairs or equipment swaps faster than contractors relying on traditional solvent-weld fittings.

Key Features

  • Heavy-duty PVC construction ensures long-term resistance to corrosion and chemical degradation.
  • Integrated O-ring provides a superior watertight seal compared to thread sealant alone.
  • FIPT threaded ends allow for easy integration with existing galvanized or PVC threaded equipment.
  • Three-piece design enables quick disassembly of system components for cleaning or winterization.
  • Precision molded threads minimize the risk of cross-threading during rapid field installation.
  • Compact profile allows for installation in tight valve boxes or crowded equipment pads.

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

Proper installation requires the use of high-quality PTFE thread seal tape or non-setting pipe dope on the FIPT connections to ensure a leak-free joint. Hand-tighten the union nut and then apply no more than a quarter turn with a strap wrench or pipe wrench to avoid over-stressing the plastic housing. Always ensure the O-ring is seated properly and free of debris before final assembly, and verify that the installation meets all local plumbing codes regarding mechanical disconnects.
