Product details
The Hayward SX200Z4 is a tank and valve O-ring measuring 2-1/4 in. inside diameter with a 1/8 in. cross section. It is the genuine Hayward part.
Where it is used
Hayward specifies this O-ring across a wide range of equipment: the S200 and S240 sand filters, the Pro Series and Pro Series Plus side mount sand filters, the Micro-Clear and Pro-Grid DE filters, the Super Star Clear cartridge filters and the SP0740 DE Selecta-Flo valve. Check the parts breakdown for your model to see exactly which position it fills.
Fitting it
Clean the groove and the mating face before the new ring goes in, then use a silicone based O-ring lubricant so it seats evenly. Do not reuse the old ring. Rubber that has been compressed in a joint for years takes a permanent set, and once the joint is opened it rarely seals again.
