Quick overview

  • Union set with O-rings The barrel nuts and unions arrive with their O-rings, so the joint seals on reassembly.
  • For the E-Series Sized for the Solaxx E-Series salt chlorine generator.
  • The usual leak point Union O-rings harden with heat and chlorine, and a dripping union is far more often the seal than the housing.
  • One part number The whole union set is ordered as PZ40-UNIONSET.
  • Plumbing hardware only This is the union side of the cell, not the cell itself and not the power supply.
  • No cutting required Replacing the union set puts the joint right without opening up the pipe run.

Product details

This is the replacement barrel nut and union kit for the Solaxx E-Series salt chlorine generator, supplied with its O-rings. The part number is PZ40-UNIONSET.

Why unions fail

The cell sits in the return line inside a housing held by two unions, and those unions are the only part of the assembly that gets taken apart regularly. Every cleaning cycles the O-rings, and chlorinated water at pool temperature slowly hardens them. Eventually one takes a set, stops sealing, and starts a slow drip at the pad that never quite goes away.

What you are ordering

The barrel nuts, the unions and the O-rings. Not the cell, not the housing and not the power supply control box, all of which are listed separately. If the leak is at the union, this is the whole repair and none of the plumbing has to be cut.

Questions and answers

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

What does the kit include?
The barrel nuts and unions with their O-rings, ordered as PZ40-UNIONSET.
Does the salt cell come with it?
No. This is the union hardware only. The E-Series cell and the power supply control box are separate items.
My union is dripping. Is this the fix?
Usually. On a union joint the seal is what fails first, and a hardened or cut O-ring will weep no matter how tight the nut goes. If the union body itself is cracked, this kit replaces that too.
Which system does it fit?
The Solaxx E-Series salt chlorine generator.
