Durable Lasco PVC adapter engineered for dependable irrigation connections. This 1" MIPT to 3/4" MIPT threaded adapter provides a secure, low-cost solution for converting between common irrigation pipe sizes in residential and commercial sprinkler systems. Constructed from PVC and rated to 150 PSI, it is specified for irrigation use only.

  • Material: Durable PVC engineered for corrosion resistance and long service life.
  • Size: 1" MIPT (male) to 3/4" MIPT (male) thread configuration for standard irrigation fittings.
  • Pressure Rating: 150 PSI — suitable for most residential and commercial irrigation applications.
  • Compatibility: Works with standard threaded risers, manifolds, valves and fittings that accept 1" and 3/4" MIPT connections.
  • Installation: Use approved PTFE (Teflon) tape or pipe thread sealant on threads. Hand-start threads, then tighten with a wrench while avoiding overtightening to prevent stress on PVC.

This adapter is intended specifically for irrigation systems; it is not certified for potable water use. It is an economical component for installers, landscapers and DIY homeowners who need a reliable threaded transition between 1" and 3/4" irrigation lines. Before installation, verify thread types and compatibility with existing fittings and follow local plumbing and irrigation codes. Store in a dry, shaded area to prolong material life; avoid exposure to direct sunlight for extended periods when possible.
