Product details

The Hayward HAXNNO1930 is the complete connector kit for attaching plumbing to a Hayward H-Series heater. It is supplied as a set, with two of every piece so both the inlet and the outlet are covered.

What is in the box

One set of 2 HAXNUT1930 union nuts, one set of 2 HAXNIP1930 CPVC nipple connectors and one set of 2 HAXFOR1930 union o-rings. Bought separately, those three part numbers are what you would be ordering anyway, and the kit removes the risk of getting two of them and discovering the third is missing with the system drained.

Sizes

The nipple is 1-1/2" Slip x 2" Spg, which is why the kit works with either 1-1/2 in. or 2 in. plumbing. That single detail is what makes it a general purpose H-Series connection kit rather than a size specific one.

Why CPVC

The nipple connectors are chlorinated PVC. The plumbing right at a heater outlet sees the hottest water in the system, and CPVC keeps its pressure rating where standard PVC starts to give. Using the specified material at the heater is the difference between a joint that lasts and one that deforms in a hot summer.

Questions and answers

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

What comes in the kit?
A set of 2 HAXNUT1930 union nuts, a set of 2 HAXNIP1930 CPVC nipple connectors and a set of 2 HAXFOR1930 union o-rings. That is the complete kit to attach plumbing to a Hayward H-Series heater, inlet and outlet.
Will it work with my pipe size?
Yes for either common size. The nipple is 1-1/2" Slip x 2" Spg, so it works with 1-1/2 in. or 2 in. plumbing.
Are the o-rings included?
Yes. The kit includes a set of 2 HAXFOR1930 union o-rings, so you are not chasing seals separately on assembly day.
Why are the nipples CPVC rather than PVC?
Because they sit at the heater, where outlet water is hottest. CPVC holds its rating at temperatures that soften standard PVC, which is why heater manufacturers specify it for the first stretch off the unit.
