A self-sealing pump union: 2" male pipe thread on one end, 2" PVC glue socket on the other, sealed by an O-ring face seal in a hand-tightened collar. Thread it into the pump volute, glue your pipe into the socket, and from then on the pump comes out of the system by hand — no cutting, no wrenches, no thread tape.
Why put unions on a pond pump
Every pump eventually needs to come out — a seal service, an impeller clean, winterizing, or replacement. With a union on each side of the pump that's a two-minute job done by hand. Without them, it's a hacksaw and a repair coupling, done in the wet. The O-ring face seal also shrugs off pump vibration and warmth, which is exactly where taped threaded joints slowly work loose.
Specifications
- 2" MIP (male iron pipe thread) × 2" slip socket for Sch 40 PVC
- High-temperature-resistant moulding, black — the style fitted as original equipment on Pentair WhisperFlo and IntelliFlo pumps
- O-ring included, seated in the collar
Fitting notes
- Buy two — one each side of the pump. One union halves the benefit.
- Hand-tight is correct. The O-ring does the sealing; a wrench on the collar cracks it.
- A smear of silicone lubricant on the O-ring at each service keeps it sealing for years. Never petroleum grease.
Goes with
See our plumbing collection for the valves, PVC and check valves either side of it — and our standing advice applies: a valve and a union on both sides of anything you'll ever service.
