I need to replace the inlet and outlet threaded connectors on my RS1000 Hayward pump. The O.D. of the pump connections is around 3 1/16th inches outside thread and 8 threads per inch.
Hello Ronvera - It sounds like you are looking for unions that screw onto the outside threads of the RS1000 pump. The unions that would work are part number 400-5570.
Thank you for shopping with INYOpools.com!
Thanks, just got them in. correct diameter but it looks like it’s the wrong thread.
That is the only option we have for external threads on the pump housing. We have another option for the internal threads on the pump housing. The part number is 21063-200-000.
