Quick overview
- Threads to hose 1-1/2 inch male pipe thread on one end, 1-1/2 inch hose barb on the other.
- Straight body A straight run rather than an elbow, for a hose that comes at the port square on.
- Smooth barb A smooth barb profile, the style Hayward specifies for this fitting.
- ProSeries and Dyna-Skim Listed for Hayward ProSeries sand filter models and the Dyna-Skim automatic skimmer.
- Genuine Hayward Factory part SPX1091Z4, not a hardware store approximation.
- Seal the threads Wrap the pipe thread with PTFE tape and hand tighten plus a turn. Overtightening a threaded plastic port is what cracks it.

Product details
The Hayward SPX1091Z4 is a straight hose adapter with a 1-1/2 inch male pipe thread on one end and a 1-1/2 inch smooth hose barb on the other. Hayward lists it for ProSeries sand filter models and for the Dyna-Skim automatic skimmer.
What it is for
Above ground equipment is plumbed in flexible hose, and the ports on filters and skimmers are threaded. This adapter is the piece in between: it screws into the threaded port and gives the hose a barb to clamp onto.
Installing it
Wrap the pipe thread with PTFE tape, thread it in by hand and give it about one more turn with a wrench. Threaded plastic ports crack when a fitting is driven in hard, and that turns a small repair into a new filter head. On the hose end, push the hose fully over the barb and set the clamp behind the last ridge.
