Description

This is the genuine Sta-Rite valve shaft O-ring, part 14971-SM10E10. It seals the shaft that the multiport handle turns, where that shaft passes out through the top of the valve.

The leak it fixes

A multiport valve has two places that commonly weep. Water coming out of the waste line when the valve is set to filter is the spider gasket. Water appearing on top of the valve around the handle is this O-ring. It is the only seal in the valve that has to stay tight while a part is moving, so it wears from use as much as from age, and once it hardens it stops following the shaft.

Valves it is listed for

Sta-Rite gives this part number for the 2 inch top mount multiport valve model 14971-TM-22-L, for the 1-1/2 inch and 2 inch side mount multiport valves, and for the American Products 5 and 8 position top mount valves in the 1-1/2 inch models 501151, 501181 and 501183.

While you are in there

Getting to the shaft O-ring means opening the top of the valve, so it is worth looking at the shaft washers and the spider gasket at the same time. Doing all of them in one visit beats taking the valve apart twice in a season.
