Lasco 437101 (437-101) Schedule 40 PVC Reducer Bushing – 1" Spigot x 1/2" Slip (Socket) – White

The Lasco 437101 (also listed as 437-101) is a Schedule 40 PVC reducer bushing used to step down from a 1" hub/socket fitting to 1/2" PVC pipe. The 1" spigot end glues into the socket of a 1" PVC fitting (tee, coupling, valve, etc.), while the 1/2" slip (socket) end accepts 1/2" PVC pipe for a solvent-weld connection.

Key Features

  • Part Number: 437101 (437-101)
  • Fitting Type: Reducer bushing
  • Size: 1" Spigot x 1/2" Slip (Socket)
  • Material: Schedule 40 PVC
  • Color: White
  • Use: Reduces a 1" socket connection down to a 1/2" glued pipe run

Common Uses

  • Reducing a 1" manifold port down to 1/2" plumbing for small accessory lines
  • Pool/spa equipment pads (small bypasses, feeder lines, drains, and sampling ports)
  • Irrigation and general water plumbing where Sch 40 solvent-weld PVC is used

Installation Notes

  • Spigot end: Glues into a 1" slip socket (hub) on another fitting (it does not glue onto 1" pipe).
  • 1/2" socket end: Glues to 1/2" PVC pipe using primer and PVC cement rated for pressure plumbing.
  • Dry-fit first: Confirm alignment and insertion depth before cementing.
  • Support the line: Reduce pipe strain so the bushing isn’t carrying bending stress.

Installation & Maintenance Tips

  • Deburr/chamfer pipe ends and keep sockets clean and dry for the strongest solvent-weld joint.
  • Use fresh primer/cement and follow cure-time guidance before pressurizing (temperature and humidity affect cure time).
  • Avoid forcing misaligned plumbing into place—pipe strain can crack fittings over time.
  • If used near equipment, add a union downstream for easier future service.
