Product details

The Aqua-Flo 91431150 is the union nut for 2 in. pump unions. It is the threaded collar that draws the union half up against the pump port and holds the joint together.

Why it is a wear part

Union nuts take the whole clamping load of the joint and they live outdoors. Between UV making the plastic brittle and the habit of reaching for a wrench when a joint weeps, they crack at the thread more often than any other piece of the union. A cracked nut cannot pull the faces together, so the joint keeps seeping no matter how far it is turned.

What you are buying

The nut only. If the union o-ring is flattened or the tailpiece is damaged, those are separate parts. Replacing the nut lets you fix the joint without cutting into plumbing that is otherwise fine.

Questions and answers

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

Does this include the o-ring and tailpiece?

No. It is the union nut on its own. The o-ring and the union half are separate parts.

What size is it?

2 in.

Why did my union nut crack?

Almost always overtightening, or years of UV making the plastic brittle. Union nuts are meant to be hand tight against a good o-ring, not driven down with a wrench.

Is it a genuine Aqua-Flo part?

Yes. It is Aqua-Flo part number 91431150.
