Lasco 897020 Schedule 80 PVC Union – 2″ Slip x Slip (Socket) – Gray
The Lasco 897020 is a Schedule 80 PVC true union fitting with 2″ slip (socket) x slip (socket) ends. It’s designed to give you a reliable, service-friendly connection in pool/spa plumbing, irrigation, and general water systems—so you can disconnect equipment or plumbing sections without cutting pipe.
Key Features
- Part Number: 897020
- Type: Schedule 80 PVC union (O-ring sealed)
- Size: 2″ (IPS)
- Connections: Slip (socket) x slip (socket) for solvent-weld installation
- Color: Gray
- Seal style: O-ring seal provides a positive seal while allowing easy disassembly
- Serviceability: Union nut allows removal of pumps, filters, valves, heaters, and manifolds without cutting pipe
- Applications: Pool/spa equipment pads, irrigation manifolds, water features, and general plumbing where frequent service may be needed
Why Add a Union?
- Makes future repairs and equipment swaps faster (no cutting/gluing during service)
- Helps reduce downtime when replacing pumps, filters, chlorinators, or valves
- Creates a clean break point in plumbing for winterization or maintenance
Installation Notes
- Slip ends are solvent-weld: Use PVC primer and PVC cement approved for pressure plumbing.
- Keep the O-ring clean: Ensure the O-ring and sealing surfaces are free of dirt and debris before tightening.
- Do not over-tighten: Tighten the union nut firmly (typically hand-tight plus a small additional turn if needed). Over-tightening can damage threads or the O-ring.
- Allow proper cure time: Let glued joints cure fully before pressurizing (cure time varies by cement, temperature, and humidity).
- Chemical compatibility: If used for chemical feed, confirm the O-ring and PVC compatibility with your specific chemical and concentration.

Installation & Maintenance Tips
- When reassembling, lightly lubricate the O-ring with a silicone-based lubricant made for pool/plumbing seals (avoid petroleum-based products).
- If you see seepage at the union nut, shut down, relieve pressure, inspect the O-ring for nicks/flattening, and re-seat it cleanly.
- Support nearby plumbing to reduce stress on the union and glued joints—pipe strain can cause leaks over time.
- Operate valves and service unions periodically (especially seasonal systems) so threads and seals don’t seize.
