Lasco 406025 (406-025) Schedule 40 PVC 90° Elbow – 2-1/2″ Slip x Slip – White
The Lasco 406025 (also shown as 406-025) is a Schedule 40 PVC 90-degree elbow with 2-1/2″ slip (socket) connections on both ends. It’s used to make a clean 90° turn in 2-1/2″ PVC plumbing for pool & spa equipment pads, water features, irrigation manifolds, and general water circulation systems.
Key Features
- Part Number: 406025 (406-025)
- Fitting Type: 90° elbow
- Size: 2-1/2″ (nominal pipe size / IPS)
- Connections: 2-1/2″ Slip (socket) x 2-1/2″ Slip (socket)
- Material: Schedule 40 PVC
- Color: White
- Typical max service temperature: Up to 140°F (PVC pressure applications)
Common Uses
- Turning a 2-1/2″ suction or return line on pool/spa equipment pads
- Manifold plumbing for water features and circulation loops
- Irrigation headers and general water plumbing using solvent-weld PVC
Installation Notes
- Slip sockets are solvent-weld: Use PVC primer and a PVC cement rated for pressure plumbing.
- Dry-fit first: Confirm alignment and clearance before gluing (larger fittings set quickly once cement is applied).
- Full insertion: Deburr/chamfer pipe ends and seat pipe fully into the sockets for maximum joint strength.
- Support the line: Add pipe supports/hangers to reduce vibration and pipe strain that can crack fittings over time.
- Cure time: Allow proper cure time before pressurizing (varies by cement type, temperature, and humidity).

Installation & Maintenance Tips
- Mark pipe insertion depth before cementing so each joint seats fully during assembly.
- For best bond strength, keep sockets and pipe ends clean and dry, and use fresh primer/cement.
- Avoid forcing misaligned plumbing into place—pipe strain is a common cause of hairline cracks and leaks.
- After startup, inspect joints for seepage and correct any alignment/support issues immediately.
- If future equipment removal is likely, add unions near the elbow to avoid cutting pipe later.
