Product details

The Waterco 63406550 is a union adaptor that takes a 2 inch connection to 2.5 inch. It is the genuine Waterco part.

What a union does for you

Unions are the reason a pump or a filter can be taken out for service without a saw. The fitting unscrews, the equipment comes out, and the plumbing stays intact. A cracked or cross threaded union is worth replacing as soon as you notice it, because that is the joint you will want to open next time.

Before ordering

Union parts are not interchangeable across manufacturers, and the details of what is included are not listed here. Compare this against the fitting you are replacing, and order any seal you need separately.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this adaptor?
It adapts between 2 inch and 2.5 inch, as Waterco part 63406550.
Why use a union instead of a glued fitting?
A union can be unscrewed, so the pump or filter can be pulled for service without cutting into the plumbing.
Will it fit another brand of equipment?
It is the Waterco part. Union threads and seats differ between manufacturers, so compare it against the fitting you are replacing before you commit.
Does it include an o-ring or nut?
The listing does not specify what is included beyond the adaptor itself. Check the fitting you are replacing and order any seal separately if you need one.
