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.
