Sch80 UNION W/O-RING SEAL (FIPT x FIPT)

Product Overview

When a main line fitting fails or a pump requires replacement during the peak of the summer heat, your crews cannot afford the downtime caused by glued joints that must be cut out and replumbed. System shutdowns lead to immediate turf stress, crop loss, and frustrated clients who expect rapid restoration of water service. With seasonal demand surging and supply chains often facing unpredictable back-orders, waiting until a leak occurs to source specialized Schedule 80 unions puts your project deadlines at risk. Professionals who stock these Lesso unions now ensure they can perform onsite repairs in minutes rather than hours, maintaining a reputation for reliability when it matters most.

The Lesso Schedule 80 Union provides a significant technical advantage over standard Schedule 40 fittings by offering superior wall thickness and a high-pressure rating suitable for demanding commercial environments. The FIPT by FIPT (Female Iron Pipe Thread) configuration allows for easy integration with threaded valves, pumps, and backflow preventers without the mess or curing time of solvent welding. By choosing a heavy duty union with a built in O-ring seal, you reduce labor costs on future maintenance calls and provide your clients with a modular system that is easier to service. Being well stocked with these components gives your company a competitive edge in bidding on high pressure municipal and industrial irrigation contracts.

Please contact our sales team for pricing on bulk quantities or for specific information regarding larger diameter configurations and alternative gasket materials.

Key Features

  • Thick wall Schedule 80 construction provides superior structural integrity and resistance to mechanical stress.
  • Precision machined FIPT threads ensure leak free connections with standard NPT threaded pipes and equipment.
  • Integrated elastomeric O-ring provides a positive seal without the need for excessive torque during assembly.
  • True union design allows for the easy removal of downstream components for cleaning or replacement.
  • High chemical and corrosion resistance makes this fitting ideal for fertigation and harsh soil conditions.
  • Knurled nut design allows for hand tightening in tight spaces where large pipe wrenches may not fit.

Common Applications

  • Commercial landscape irrigation
  • Agricultural and crop irrigation
  • Sports turf and golf course maintenance
  • Municipal parks and public spaces
  • Chemical and fertigation delivery
  • Pool and spa water feature plumbing

Installation Notes

Ensure that all threaded male ends are clean and free of debris before assembly. Use a high quality PTFE thread sealant tape or non hardening pipe dope on the FIPT connections to ensure a watertight seal. Tighten the union nut by hand until snug; then use a strap wrench or pipe wrench to turn the nut an additional one quarter to one half turn. Do not over tighten as this can compress the O-ring excessively or crack the PVC housing. Always follow local plumbing codes regarding the use of unions in pressurized main lines.
