Installation & Compatibility
This union is intended for use on 2″ PVC plumbing systems. The slip socket end is solvent-cemented to 2″ PVC pipe using appropriate primer and cement. The 2″ MPT end threads into a compatible 2″ female pipe thread port on your pump, filter, heater, or fitting. Always verify thread type and size on your equipment before installation.
Ensure the O-ring is properly seated in the union before tightening. Hand tighten and then snug with appropriate tools if necessary, taking care not to overtighten and damage threads or the union body.
Maintenance Tips
- Periodically inspect the O-ring for cracks, flattening, or wear.
- Use a silicone-based lubricant on the O-ring to maintain a smooth seal.
- When servicing equipment, loosen the union instead of cutting pipe for easier reassembly.
- Protect plumbing and unions from freezing conditions where applicable.
Benefits
Adding unions at key equipment connections makes maintenance and equipment replacement faster and cleaner, reducing the need for cutting and re-gluing PVC. The CMP 21063-210-000 provides a robust, self-sealing connection that helps maintain leak-free operation in residential and commercial pool and spa systems.
