- Two inch size The 2 inch half of the union, matched to the filter port it threads into.
- DEPB and HRPB Listed for the DEPB vertical D.E. filter and the HRPB high rate sand filter.
- Half union This is one half of the union, so order what your job actually needs before you break the plumbing apart.

Product details
Pentair U11-198P is the 2 inch half union adapter used on the DEPB vertical D.E. filter and the HRPB high rate sand filter. It is the genuine Pentair part.
What a half union is
A union joins two lengths of pipe with a threaded collar so that the joint can be taken apart by hand. This listing is one half of that assembly, the adapter that goes on the filter side. It is worth being clear about which half you are missing before ordering, since the two sides are not interchangeable.
Why unions matter on a filter
Filters have to come off for service, and without unions that means cutting and re-gluing pipe every time. A sound union is the difference between a fifteen minute filter pull and an afternoon of plumbing. When you reassemble one, check the o-ring in the joint. A union that drips is far more often a hardened seal than a failed adapter.
