Waterway 419-4120 2" Inside Coupler (Sch 40 PVC Insider Coupling, White)
The Waterway 419-4120 is a 2" inside coupler (also called an insider coupling) designed to solvent-weld inside the bore of 2" Schedule 40 PVC pipe. It’s commonly used for tight plumbing repairs where you need to join two pipe ends without adding extra length like a standard slip coupling.
Key Features
- Inside-pipe repair fitting: glues inside 2" Sch 40 PVC pipe (inside-slip on both ends)
- Space-saving design: ideal when you can’t move equipment or don’t have room for a standard coupling
- Helps maintain existing plumbing footprint during repairs and modifications
- Durable white PVC construction for pool and spa plumbing applications
Common Uses
- Repairing a cracked or cut section of 2" PVC pipe when pipe length is limited
- Joining two 2" pipe ends without changing alignment of valves, unions, or equipment
- Quick fixes on pool/spa suction and return plumbing (where inside-coupler style fittings are appropriate)

Installation Notes
- Dry-fit first and confirm the pipe ends are round and clean; remove burrs and debris.
- Use PVC primer and cement rated for pressure plumbing and follow cure times based on temperature/humidity.
- Because this fitting glues inside the pipe, make sure the inside pipe surface is clean and free of scale/film for best bonding.

Maintenance Tips

- Support nearby plumbing to reduce vibration stress on glued joints.
- When winterizing, drain lines appropriately to help prevent freeze damage that can crack fittings and pipe.
