Lasco 437338 (437-338) Schedule 40 PVC Reducer Bushing – 3" Spigot x 2" Slip (Socket) – White
The Lasco 437338 is a Schedule 40 PVC reducer bushing used to step down from a 3" hub/socket fitting to 2" PVC pipe. The 3" spigot end is sized to glue into the socket of a 3" PVC fitting (like a tee, coupling, or valve), while the 2" slip (socket) end accepts 2" PVC pipe for solvent-weld installation.
Key Features

- Fitting Type: Reducer bushing
- Size: 3" x 2"
- Connections: 3" Spigot (SPG) x 2" Slip (Socket)

- Use: Reduces a 3" socket connection down to a 2" glued pipe run

- Equipment pad manifolds where a 3" main line branches into 2" plumbing
- Reducing at tees, valves, unions, or couplings without changing the 3" hub fitting

Installation Notes
- Spigot end: Glues into a 3" slip socket (hub) on another fitting (it does not glue onto 3" pipe).
- 2" socket end: Glues to 2" PVC pipe using primer and PVC cement rated for pressure plumbing.
- Dry-fit first: Confirm alignment and insertion depth before cementing.
- Avoid over-cementing: Excess cement can squeeze into the flow path—use proper primer/cement technique.

Installation & Maintenance Tips
- Deburr and chamfer pipe ends before gluing to help prevent pushing cement out of the joint.
- Support nearby plumbing to reduce pipe strain—stress is a common cause of hairline cracks and leaks over time.
- Allow proper cure time before pressurizing (temperature and humidity affect cure time).
- If you expect frequent equipment removal, add unions near the reducer location to avoid cutting pipe later.
