Sch80 COUPLING (FIPT x FIPT)

Product Overview

System shutdowns during the peak of summer heat can result in devastating turf damage and tens of thousands of dollars in lost plant material. When a mainline fails or a leak develops, the pressure to restore service is immediate; yet supply chain disruptions often leave contractors waiting weeks for heavy duty industrial fittings. Failure to have high pressure Sch80 couplings on hand leads to missed project deadlines and failed inspections when inspectors find under-rated components on commercial sites. Planning ahead by securing your inventory now provides the relief of knowing your crews are equipped to handle emergency repairs without the stress of local back-orders or long lead times.

Lesso Schedule 80 couplings provide a significant technical advantage over standard Sch40 alternatives by offering a thicker wall construction that handles higher surge pressures and mechanical stress. These FIPT by FIPT threaded fittings allow your crews to make secure connections without the cure time required for solvent welding, saving valuable labor hours on the job site. Using industrial grade Schedule 80 PVC ensures a longer service life and fewer warranty callbacks compared to lower grade options. Maintaining a stock of these durable fittings gives your business a competitive edge by allowing you to complete high pressure installations more reliably than competitors who rely on standard hardware store components.

Product Specifications

Specification Detail
Material High Grade Polyvinyl Chloride (PVC)
Connection Type FIPT x FIPT (Female Iron Pipe Thread)
Schedule Schedule 80
Maximum Pressure Varies by size; typically rated up to 850 PSI at 73°F
Color Dark Gray
Standards ASTM D2467 compliant for threaded fittings

Available Models & Sizes

The Lesso Sch80 threaded coupling is available in a range of diameters from 1/4 inch through 4 inches to accommodate various mainline and lateral pipe sizes. Please contact our sales team for current availability of large diameter configurations or bulk pricing for full crate orders.

Key Features

  • Heavy wall Schedule 80 construction provides superior resistance to internal pressure and external impact.
  • Precision machined FIPT threads ensure a tight, leak free seal when used with appropriate pipe sealant.
  • Dark gray PVC material offers enhanced UV resistance for outdoor or above ground installations.
  • Chemically resistant properties make these couplings suitable for fertigation and harsh soil environments.
  • Threaded design facilitates easy system maintenance and component replacement without cutting pipe.
  • Compatible with all standard NPT threaded PVC and metal irrigation components for versatile integration.
  • Corrosion proof material eliminates the scaling and pitting common with galvanized metal fittings.

Common Applications

  • Commercial landscape irrigation
  • Agricultural and crop irrigation
  • Sports turf and golf course maintenance
  • Municipal parks and public spaces
  • Greenhouse and nursery operations
  • Chemical and fertigation delivery

Installation Notes

For a secure and leak free installation, apply a high quality non-hardening thread sealant or PTFE tape to the male threads before assembly. Hand tighten the connection and then turn an additional one to two turns with a strap wrench to avoid over-stressing the plastic threads. Always ensure that the threads are clean and free of debris to prevent cross-threading. All installations must comply with local plumbing codes and manufacturer pressure ratings for the specific pipe size being utilized.
