This 1.5" heater union split nut assembly receives mostly positive feedback. Customers said it "worked as required" for pool heater connections and praised the helpful service. However, one shopper reported fit issues with 1-1/2" pipe threads, suggesting potential compatibility concerns. Overall, valued for good pricing and functionality.

I wouldn't buy these

First, I was advised to buy these by customer service.. 2nd, they didn't fit over the 1-1/2 pipe thread on the pump. Cost more to return then worth. Got correct set elsewhere
