62 mm pump union for 50 mm pipe
This union has a nut that fits on pumps with a male 62 mm outside diameter thread (this type of thread is known as 1.5-inch MBT), and connects to 50 mm pipe.
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.
Inside diameter of the thread on the tightening ring: 60 mm or 1.5-inch FBT
Outside diameter of the corresponding male thread on the pump: 62 mm
Inside diameter smooth side: 50 mm
