Lasco

LASCO Fittings, Inc. specializes in injection-molded PVC and CPVC fittings for Irrigation, Plumbing, Industrial, and Pool/Spa applications. Build clean, code-friendly systems with consistent fit, smooth sockets, and dependable threads.

Shop by need

  • Core fittings: elbows, tees, couplings, caps, plugs, bushings, adapters (slip/socket, FNPT/MPT)
  • Irrigation: manifold fittings, swing joints & risers, nipples, barbed/poly adapters
  • Plumbing: CPVC CTS fittings, transition adapters, repair couplings
  • Industrial / Pool/Spa: Schedule 80 options, large-diameter PVC, unions & check fittings
  • Sizes & materials: common 1/2"–2" (select larger), PVC Sch 40/80, CPVC where specified

Quick choosing tips

  1. Match material & schedule: keep PVC Sch 40/80 consistent across a pressure line; use CPVC for higher temp where required.
  2. Pick the connection type: solvent-weld (slip/socket) for permanent joins; threaded (FNPT/MPT) where serviceability matters.
  3. Use the right sealants: primer + cement for sockets; PTFE tape or thread sealant for NPT threads (no glue on threads).
  4. Check ratings: confirm pressure/temperature and local code for irrigation vs. pool/spa vs. industrial runs.

Use filters to narrow by size, schedule, connection (slip/thread/barbed), and application. Orders ship fast from Big Frog Supply—need help matching parts? We’ve got you.

Pro tip: Dry-fit first, deburr and clean cuts, then apply primer and cement per manufacturer timing. Allow proper cure before pressurizing and support lines to prevent stress on fittings. Not sure which LASCO part number fits your setup? Message us—we’ll help you spec it.
