Product details

The Hayward StarClear Auto Air Relief Tube with Screen, CX800Z4A, is the air relief tube, supplied with its screen, for the Hayward StarClear Plus C751 and C900 cartridge filters and the StarClear II C800. It is the Brand OEM Hayward part and a direct swap for the tube inside the filter head.

What it does

The tube sits inside the filter head and carries air trapped in the tank up to the relief valve, where it can be bled off. The screen on the end keeps debris out of that path. A tube that has cracked, broken off or lost its screen leaves the air path open to dirt or cut short.

Fit

Hayward's StarClear Plus owner's manual lists the air relief tube for the C900 as CX800Z4, and this CX800Z4A listing is that tube with its screen. The larger models use their own tubes: CX1100Z4 for the C1200 and CX1750Z4 for the C17502. Check the model on your filter before you order.

When to replace it

Change it when the tube is cracked, broken off or missing its screen. That is usually found during a filter head teardown for a cartridge or o-ring service, which is also the easiest time to swap it.
