Hayward SPX1105Z4 Hose Adapter - 1-1/2 inch MPT x 1-1/2 inch Barbed

What This Part Is Used For
The Hayward SPX1105Z4 Hose Adapter connects compatible Hayward chlorinator or plumbing components to flexible pool hose. It provides a 1-1/2 inch MPT connection on one side and a 1-1/2 inch barbed hose connection on the other.

Why This Part Matters
A cracked or stripped adapter is a common source of drips and air leaks at above ground equipment pads. Poor sealing can reduce flow and make priming harder. Replacing the adapter restores a tight, reliable hose-to-thread connection.

About the Hayward Brand
Hayward manufactures pool equipment across pumps, filters, heaters, automation, cleaners, chlorination, and service parts. Their above ground components are built around standard hose and fitting sizes to keep installs straightforward. Genuine adapters help maintain proper fit and sealing with Hayward systems. This reduces leaks and call-backs.

Common Service Context
Techs typically replace hose adapters during spring openings, after winterizing, or when chasing small pad leaks. You will often see failure after hoses have been removed and reinstalled multiple seasons in a row.
