Praher 2" MPT x 2" Slip Union Adapter
The Praher Union 89-253-10006 is a Series 906 adapter union designed for professional pool plumbing applications where strength, serviceability, and leak prevention matter. This union features a 2-inch male pipe thread (MPT) x 2-inch slip (socket) configuration and includes an O-ring seal for a secure, watertight connection.
It is commonly installed at pump volutes and suction connections to reduce stress on plumbing, simplify future service, and help prevent failures caused by vibration or thermal expansion.
Why Unions Matter in Pool Plumbing
Rigid, hard-plumbed connections at pumps are a common failure point in pool systems. A properly installed union allows components to be removed without cutting pipe and helps absorb movement and stress.
Common issues unions help prevent include:
-
Cracked pump volutes
-
Leaks at threaded connections
-
Stress fractures from vibration
-
Difficult or destructive pump removal
Using a high-quality union like this Praher model improves system longevity and simplifies maintenance.
Designed for Praher Series 906 Applications
This union is manufactured to Praher Series 906 specifications, ensuring precise thread engagement, smooth sealing surfaces, and reliable long-term performance. The integrated O-ring provides consistent sealing without over-tightening, reducing the risk of thread damage.
The 2″ MPT x 2″ slip configuration makes it ideal for adapting threaded pump ports to standard 2-inch PVC plumbing.

-
Pool pump installations
-
Suction and return plumbing

Equipment pad upgrades or repairs
-
Situations requiring future service access
Installation should follow standard pool plumbing practices, including proper thread sealant on the MPT side.
