Product details

The Sta-Rite U43-42SS is a standard 3/8 in flat washer, the hardware washer Sta-Rite lists on its pump parts diagrams. It is the genuine Sta-Rite part.

Where it is used

It appears on the Dyna-Glas and Dyna-Max diagrams and on the Max-E-Glas and Dura-Glas diagrams. Small as it is, the washer does real work: it spreads the clamping load of a bolt across a wider area so the head does not bite into the housing.

When to replace

Pump hardware lives outdoors in a wet, chemically active spot. Washers pit, swell and lose their flatness, and a washer that no longer sits flat concentrates the load exactly where you do not want it. If you have a pump apart and the hardware looks tired, replacing it is inexpensive insurance.

Questions and answers

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

What size is this washer?
It is a standard 3/8 in flat washer, Sta-Rite part U43-42SS.
Which pumps is it listed for?
Sta-Rite shows it on the Dyna-Glas and Dyna-Max parts diagrams and on the Max-E-Glas and Dura-Glas diagrams.
Does it come in a set?
The listing is for the washer as Sta-Rite catalogs it. Most assemblies use several, so order the quantity your job needs.
Why bother replacing a washer?
A washer spreads the clamping load of the bolt. When it corrodes and no longer sits flat, the load concentrates and can crack the plastic or casting it is clamping against.
