Description
Lasco 437131 (437-131) Schedule 40 PVC Reducer Bushing – 1″ Spigot x 3/4″ Slip (Socket) – White
The Lasco 437131 (often shown as 437-131) is a Schedule 40 PVC reducer bushing that steps down from a 1″ hub/socket fitting to 3/4″ PVC pipe. The 1″ spigot end is designed to glue into the socket of a 1″ PVC fitting (tee, coupling, valve, etc.), while the 3/4″ slip (socket) end accepts 3/4″ PVC pipe for a solvent-weld connection.
Key Features
- Part Number: 437131 (also listed as 437-131)
- Fitting Type: Reducer bushing
- Size: 1″ Spigot x 3/4″ Slip (Socket)
- Material: Schedule 40 PVC
- Color: White
- Use: Reduces a 1″ socket connection down to a 3/4″ glued pipe run
Common Uses
- Stepping down a manifold port without changing the larger hub fitting
- Pool/spa equipment pad plumbing (auxiliary lines, bypasses, small returns)
- 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).
- 3/4″ socket end: Glues to 3/4″ PVC pipe using primer and PVC cement.
- 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 and chamfer pipe ends before gluing to help prevent wiping cement out of the joint during assembly.
- Use the correct primer/cement and follow cure-time guidance before pressurizing (temperature and humidity affect cure time).
- Keep sockets and pipe ends clean and dry for the strongest solvent-weld bond.
- Use pipe supports to reduce vibration and stress near equipment pads and valves.
- If you expect future equipment removal, add a union nearby to avoid cutting pipe later.
