Lasco 1" female-thread manifold cap with integrated O-ring (SKU 1348-010) provides a reliable, leak-resistant seal for 1" irrigation manifolds and valve assemblies. Manufactured in Schedule 40 PVC, it’s designed for residential and commercial irrigation use and installs quickly by hand tightening.

  • Brand & Model: Lasco 1348-010 — 1" female-thread manifold cap with factory-installed O-ring.
  • Material: Schedule 40 PVC for corrosion resistance and long-term performance in outdoor irrigation systems.
  • Pressure Rating: Rated to 150 psi for typical irrigation operating conditions; suitable for most residential and commercial systems.
  • Installation: Hand-tighten recommended; O-ring creates a positive seal so Teflon tape is not required on the cap itself—avoid over-tightening.
  • Use & Limitations: Intended for irrigation use only. Do not use for compressed air, gases, or with liquids not recommended by the manufacturer.
  • Compatibility: Fits 1" manifold assemblies and valve connectors designed for 1" female-thread (FTHD/FPT style) connections.

This compact manifold cap with O-ring offers a simple, dependable way to close unused manifold ports or protect valve openings during maintenance. Keep spare O-rings on hand and inspect seals periodically; consult manufacturer literature for system-specific guidance and torque recommendations.
