The Lasco 1-1/2 in male reducing adapter (MPT x slip) is a Schedule 40 PVC fitting engineered to create a secure transition from 1-1/2 inch threaded pipe to 2 inch slip (socket) pipe. Designed for reliability in irrigation, pool plumbing, and general PVC systems, this adapter combines a threaded male connection with a solvent-weld slip socket to deliver a leak-resistant join when installed correctly.

  • Material: Schedule 40 PVC for strong, chemical-resistant performance in outdoor and indoor piping systems.
  • Connections: 1-1/2 in MPT (male pipe thread) to 2 in slip/socket — ideal for reducing between threaded and solvent-weld runs.
  • Installation: Threaded male end seals with PTFE tape or thread sealant; slip/socket end is joined with PVC primer and cement per manufacturer guidelines.
  • Applications: Commonly used in irrigation, pool plumbing, drainage setups, and general non-pressurized to pressurized PVC transitions; verify local codes for potable water use.
  • Size & Identification: Manufacturer part number (MPN) 436213 — compact profile fits tight runs and retrofit jobs.
  • Durability & Care: PVC resists corrosion and many chemicals; avoid prolonged exposure to solvents not rated for PVC and support piping to minimize stress on fittings.

This adapter is a practical choice when you need a dependable reducer between threaded and solvent-weld PVC piping. Installers should follow local plumbing codes, use appropriate primer and cement on the slip end, and apply thread sealant on the MPT end for pressure applications. For project quantities, case-pack options are available under SKU 436213-10.
