This is a genuine Davey spare-part pack of two Gulfstream blanking plugs designed for the Crystal Clear ER 225 and ER 270 cartridge filter models (DCC225EU and DCC270EU). These plugs seal unused inlet or drain ports on the filter tank, maintaining a pressure-tight system and preventing leaks during normal operation.<\/p>\n
These plugs are factory-specified for the Davey Crystal Clear ER 225 (DCC225EU) and ER 270 (DCC270EU) cartridge filter tanks. They are not interchangeable with earlier non-ER Crystal Clear models or with the smaller ER 135\/180 variants \u2014 always verify your filter model number before ordering.<\/p>\n
Davey’s Crystal Clear ER filter tank operates under pool system pressure, so an ill-fitting or non-OEM plug risks slow leaks, pressure loss, or tank damage over time. A genuine Davey Gulfstream plug is precision-moulded to match the port thread and sealing surface of the ER-series tank exactly, ensuring a reliable, long-lasting seal. Supplied in a pack of two so you have a ready spare on hand.<\/p>\n
Turn off the pump and fully relieve system pressure before removing or installing any port plug. Thread the Gulfstream plug into the unused inlet or drain port by hand, then snug firm \u2014 do not overtighten. Restart the system and inspect for any sign of weeping around the plug before returning the filter to service.<\/p>","protected":false},"excerpt":{"rendered":"
