Davey – Air Relief Valve O-Ring for Crystal Clear ER 135 / 180 (Pack of 3)

This is a genuine Davey spare part — a pack of three replacement o-rings designed to seal the air relief valve on the Crystal Clear ER 135 and ER 180 cartridge filters (models DCC135EU and DCC180EU). The air relief valve is used at every start-up and service to purge trapped air from the filter tank; its o-ring is a small but critical seal that prevents water and air leaks at the valve body. Replacing a worn or compressed o-ring restores a reliable, leak-free seal and ensures the valve functions correctly during pressurised operation.

Kompatibilitás

This o-ring pack is confirmed for the Davey Crystal Clear ER Series cartridge filters in the 135 sq ft (DCC135EU) and 180 sq ft (DCC180EU) configurations — the European variants of the Crystal Clear ER range. Always verify your model number before ordering to confirm fitment. If you are unsure, the model label is located on the filter tank body.

Miért fontos az eredetiség?

The Crystal Clear ER filter operates at up to 250 kPa working pressure. A genuine Davey o-ring is manufactured to the exact material specification and dimensional tolerances required to maintain a safe, lasting seal at these pressures. Non-genuine alternatives may use incompatible rubber compounds that swell, harden, or fail prematurely, leading to air or water leaks at the valve — and potential safety risks. Buying genuine also keeps your Davey warranty intact.

Telepítés

Always isolate and fully depressurise the filter system before working on the air relief valve — use the manual air bleed to release pressure before removing the valve. Remove the old o-ring, clean the seating surface, and fit the new o-ring dry or with a silicone-compatible lubricant (never petroleum-based products such as Vaseline, which can cause rubber to swell). The pack of three provides spares for future seasonal maintenance, making it a cost-effective service item to keep on hand.
