Lasco 429005 (429-005) Schedule 40 PVC Coupling – 1/2" Slip x Slip (Socket) – White
The Lasco 429005 (also shown as 429-005) is a Schedule 40 PVC straight coupling used to join two pieces of 1/2" nominal PVC pipe in a solvent-weld (glue) system. Both ends are slip (socket) connections, making it a simple, low-profile fitting for pool/spa plumbing, irrigation, and general water lines.

Installation Notes
- Slip ends are solvent-weld: Use PVC primer and PVC cement rated for pressure plumbing.
- Full insertion matters: Deburr/chamfer pipe ends and seat pipe fully into each socket.

Installation & Maintenance Tips
- Mark insertion depth before gluing so joints seat fully during assembly.
- For best bond strength, keep sockets and pipe ends clean and dry during cementing.
- If you expect frequent equipment removal, use a union nearby instead of relying on a glued coupling.
- After startup, inspect joints for seepage and correct any alignment/support issues immediately.
