These seals are used at key joints on the filter and valve connections to keep the system watertight. The kit is used on the equipment pad during filter service.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWhy This Part Matters\u003c\/strong\u003e\u003cbr\u003e Flattened or cracked O-rings are a common cause of filter leaks and air intrusion. Leaks at the filter can waste water, create pad damage, and cause priming problems depending on where the seal sits. Replacing O-rings during service helps restore reliable sealing and reduces repeat visits. Correct seals also help prevent overtightening that can crack housings and clamps.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eKey Features and Specifications\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eManufacturer part number: VLX4004A\u003c\/li\u003e \u003cli\u003eO-ring kit for compatible Hayward VL Series filters\u003c\/li\u003e \u003cli\u003eUsed to restore watertight sealing during filter service\u003c\/li\u003e \u003cli\u003eHelps prevent leaks and air intrusion at filter joints\u003c\/li\u003e \u003cli\u003eFor equipment pad filtration maintenance\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eInstallation and Fitment Guidance\u003c\/strong\u003e\u003cbr\u003e Depressurize the filter before opening any clamps or removing the valve.
