The perfect part for any spa
Aquarius Spa Parts
Best to use a plumbing cleaner then pipe cement to assemble. Pipe work pushes inside this part at the female end.
Assemble through the spa shell with silicone you can use a gasket instead of the silicone but not both together as this often causes the gasket to spurge out the side and would cause a leak.
Used to drain water from the Spa when emptying.
