Product details

Waterway 400-5421 is the two inch split nut, supplied with its screws. It is a compression style nut that measures 3-1/16 inch inside diameter when closed.

Why a split nut

A split nut is made in two halves that close around the fitting and pull together with screws. That means the joint can be made up or taken apart without cutting into the plumbing or unthreading a run of rigid pipe, which is the whole reason the part exists.

Identifying it

The manufacturer information for this nut carries two numbers: the catalog part number 400-5421, and 415--5160 stamped into one side of the part itself. Order by the catalog number and do not be surprised when the stamp reads differently. Check the 3-1/16 inch closed inside diameter against your fitting if you are unsure of the size.

Questions and answers

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

What is a split nut?
It is a union nut made in two halves. It closes around the fitting and is drawn together with screws, which means it can be fitted without breaking into the pipe run.
What size is it?
Two inch, with an inside diameter of 3-1/16 inch when closed.
Why is a different number stamped on it?
The manufacturer information lists the catalog part number as 400-5421 while noting 415--5160 stamped into one side of the part. Both readings come from the manufacturer, so order by 400-5421 and expect the stamped number to differ.
Do the screws come with it?
Yes. The nut is supplied with its screws.
