Lasco 429-015 is a durable Schedule 40 PVC slip coupling designed to join two 1-1/2 in nominal PVC pipes with socket (slip) connections. Manufactured from white PVC, this coupling provides a smooth internal bore for low pressure loss and consistent solvent-welded seals when installed with the proper primer and cement. It is commonly used in irrigation, pool/spa plumbing, and other cold-water piping systems where Schedule 40 fittings are specified.

  • Size: 1-1/2 in nominal (fits standard 1-1/2 in Schedule 40 PVC pipe).
  • Connection: Socket x Socket (slip x slip) for solvent-weld installation.
  • Material: Rigid PVC, white finish compatible with Schedule 40 systems.
  • Standards: Manufactured to Schedule 40 dimensions and commonly listed to ASTM D2466; check the product datasheet for specific certifications.
  • Performance: Suitable for typical cold-water, irrigation, and pool plumbing; follow temperature and pressure limits for Schedule 40 PVC.
  • Installation: Clean pipe ends, apply approved primer and PVC cement, insert pipe fully, rotate slightly, and allow recommended cure time before pressurizing.

This coupling is a straightforward, economical solution for joining 1-1/2 in PVC lines. For code compliance or potable-water applications, confirm the manufacturer’s technical data sheet and any required NSF/ANSI certifications before use. Do not use PVC fittings for compressed air or where elevated temperatures exceed PVC Schedule 40 limits.
