78 mm pump union for 2″ pipe

This union has a nut that fits on pumps with a 78 mm outside diameter thread (this type of thread is known as 2-inch MBT), and connects to 2-inch pipe.

It is compatible with several pump brands, including Waterway, LX Whirlpool, Aqua-Flo ITT/HydroAir and Balboa.

If the nut breaks, you can replace it with a two-part nut that is screwed together, and therefore perfect for repairs when you need to avoid cutting pipe.

The o-ring is provided.

This union does not fit pumps manufactured by Espa or Davey Spa Power.
