- The clip, not the union This listing is the C clip alone. The union collar and the union seal are separate parts.

Product details
The Pentair 178732Z is the union nut C clip, the small retaining clip that holds a union nut in place. It is the genuine Pentair part.
Why a clip is worth ordering
It is one of the least expensive parts on the equipment pad and one of the most annoying to be without. The clip keeps the union nut captive so the joint stays where it was set. Lose one during a service and the union will not hold properly, which shows up as a weep at the joint or a nut that keeps backing off.
Ordering
This listing is the clip by itself. A 2 in. union collar and a union diamond seal are the parts most often bought with it, and if the union is already apart it is sensible to replace the seal while you are there.
