Quick overview
- Cap and gasket together Both pieces come in the one part, so the sealing surface is renewed with the cap.
- Check the stamp S-180-H is stamped into the back of this drain cap; that mark is how you confirm you have the right one.
- 2005 and prior This is the older style cap. Hayward changed the drain cap assembly for 2006 and later filters.
- Pro Series, top and side mount Fits Pro Series and Pro Series Plus sand filters in both top mount and side mount configurations.
- Also E-Series Listed for the E-Series top mount sand filters E-100, E-200 and E-250.
- Stops a winter leak The drain cap is what holds the tank closed after a winterizing drain, and a cracked cap or flattened gasket weeps all season.

Product details
The Hayward SX180HG is the drain cap and gasket for Hayward sand filters built 2005 and prior. It is the genuine Hayward part and comes with its gasket.
Identifying the right one
Hayward changed this part for filters built from 2006 onward, and the two are not interchangeable. The way to tell is the stamp: S-180-H is molded into the back of this cap. If your old cap carries that mark, this is the replacement.
Which filters
Pro Series side mount S-210S, S-220S, S-244S, S-310S and S-360S; Pro Series Plus side mount S-311SX, S-311SXV and S-360SX; Pro Series top mount S-140T, S-144T, S-164T, S-166T, S-270T2, S-310T and S-310T2; and E-Series top mount E-100, E-200 and E-250.
Why it fails
The drain cap is opened once a year at most, usually to winterize, and then torqued back down onto a gasket that has been sitting compressed since the last time. The rubber takes a set and stops sealing, and the plastic threads crack if the cap was ever forced or left out in a freeze. Because both failures look the same from outside, the cap and gasket are sold as one part.
