Product details
The Sta-Rite PKG 188 is a 2 inch by 2 inch slip union half. Both ends are slip, so it solvent welds onto rigid 2 inch PVC pipe.
Where it is used
It appears on Sta-Rite Dyna-Glas and Dyna-Max pumps, on the Dyna-Pro and Dyna-Pro E medium head pumps, on the Max-E-Pro series, and in the Pentair MasterTemp gas heater water system. That breadth is normal for a union half, which is a plumbing part rather than a model specific casting.
Why unions earn their place
A union at each port is what lets a pump or heater come off the pad without a saw. When a union half cracks at the threads or the pipe stub, replacing it is far cheaper than reworking the plumbing, and it keeps the next service call simple.
On assembly
This listing is a single union half, so count your ports. Put a silicone based lubricant on the o-ring before you tighten it up, and hand tight is usually enough.
