Molly Abraham –
Installed the 20mm adapter on my pond filter and it fits perfectly. The connection is secure and water flow is consistent. Works well with the corrugated pipe I already have.
Joseph McDonald –
The 13mm version fits my small UV clarifier. Easy to attach and doesn’t leak after a week of use. Good for small setups.
Irene Dowd –
Used it with a new flexible PVC pipe and found it to be a reliable connection point. No leaks observed after several days of operation.
