Part # 5020-134
Manufacturer Code R0446102
PUMP UNION, 2-1/2"" SLIP x 3"" SPG (SET OF 2)
I have a Jandy SHPM1.5. I need to make sure which is he right part. I don't know if it should be the R0446102 or R0446101. Can you help?

Hi Enrique, the difference between these two union kits is the diameter of the PVC that you have on-site going to and from the pool pump. One set is for plumbing set up with 2.5 inches and the other for 3-inch plumbing. Essentially you will need to measure your plumbing inner diameter.
