Spaquip 40mm threaded, 50mm Spg x 40mm Skt Heater Tee Male Tail Union Body

Spaquip / Davey 'male tail' threaded union section with 50mm/2" spigot x 40mm/1.5" socket.

Thread size is 40mm union size (approx 70mm OD)
This is a specialty component used on (and supplied with) Spa Power 400 heater tees, and suits all older Pulsar, 2095 & Intuitive 50mm heater tees as well.
This component is used for 2 purposes:
1. to allow the heater tee to be installed mid plumbing away from the pump. In this case 40mm / 1.5" pipe can glue straight inside this fitting or 50mm /2" fittings such as couplings or elbows can glue straight over the outside of this fitting.
2. to convert the heater tee to suit a replacement pump that does not have the original Spaquip 40mm MAC thread. ie if the pump is replaced with an Aquaflo XP2, Davey QB, Piranha, LX or other pump fitted with 50mm/2" unions. In these cases, this male tail fitting will glue straight into the new pump's union and the heater tee can thread straight onto it.
