## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by T***R on January 8, 2025*

I have an outdoor wood furnace that heats water and circulates into the house for heat. It uses 3 circulation pumps and of them started leaking at the gasket, this product was perfect to reseal the pump to the pipe, no more leaking.

### ⭐⭐ Cheap still works
*by A***R on May 27, 2025*

Casting is cheap and slightly crooked. Took extra dope to seal them up after a couple trys

### ⭐⭐⭐⭐⭐ Great
