Product details

The Hayward HAXNUT1930 is the union nut for the H-Series heater plumbing connection, supplied as a 2 pack.

What it fits

Hayward lists it for induced draft heaters, the Electronic ED2 style, the Millivolt and Electronic ED1 style, and the H150 through H400 millivolt and electronic ignition pool and spa heaters.

Why two

A heater has a union at each side, and the two nuts age together under the same heat and the same chemistry. The pack covers both, so you are not back at the equipment pad in a month for the other one.
