A flexible coupling joins two pipe ends with a rubber sleeve and two stainless band clamps — no glue, no primer, no perfect alignment, removable whenever you need back in. On koi ponds this is the classic repair and connection fitting for gravity bottom-drain runs, where 4" pipe meets a settlement chamber and a glued joint would make future service miserable.
Sizes
- 1-1/2", 2", 3", 4" and 6" — same size both ends; joins PVC to PVC, and PVC to cast iron, steel or copper of the same size
The one rule with flexible fittings
Elastomeric couplings are for drain and gravity lines, not pressure. Bottom drain to filter by gravity: perfect. Pump discharge: glue it. If a coupling weeps on a gravity line, the fix is repositioning the clamp, not cranking it.
Goes with
Different pipe sizes meeting? Use a reducing coupling. Dead-ending a stub? The flexible caps. Bottom drains themselves are here.
Why buy from ChampKoi?
ChampKoi has kept koi pond plumbing tight from our San Jose facility since 1998. The 4" coupling is the one every gravity-fed build eventually thanks itself for.
