Hayward FILTER LID W/LOCK RING (135-175)

The Hayward Filter Lid with Lock Ring (135–175) is a durable upper housing component designed for certain Hayward cartridge filter models, providing a secure, pressure‑resistant seal that keeps the filtration system operating safely and efficiently. The integrated lock ring ensures the lid remains firmly fastened under varying pressure levels, preventing leaks and maintaining proper alignment between the lid and filter body. Its robust, chemical‑resistant construction allows it to withstand long‑term exposure to treated water, UV light, and outdoor conditions without warping or cracking. Because it is a moderately sized molded lid paired with a locking mechanism, the estimated weight generally falls in the range of 1.5 to 3 pounds.
