This is a genuine Fluidra replacement O-ring measuring \u00d8110.5 \u00d7 5.6 mm, designed as a sealing component within the arm collector assembly of the Fluidra PTK 1200 mm commercial sand filter in 650 mm and 800 mm diameter models. It provides a reliable, pressure-resistant seal at a key junction within the filter’s internal distribution system, preventing water bypass and maintaining filtration efficiency.<\/p>\n
This O-ring is a direct spare for the Fluidra PTK 1200 mm arm filter assembly, specifically covering the \u00d8650 mm and \u00d8800 mm tank variants. The PTK 1200 series features a 1.2-metre filter bed and an arm collector underdrain system, used widely in commercial and large residential pool installations. Always cross-reference your filter’s assembly diagram to confirm this O-ring’s position before ordering.<\/p>\n
Genuine Fluidra sealing components are manufactured to precise dimensional tolerances, ensuring a correct fit and long service life under the filter’s operating pressures. An ill-fitting or substandard O-ring can lead to internal water bypass, reduced filtration performance, or pressure loss. Sourcing the correct OEM part eliminates guesswork and helps maintain the filter’s certified performance.<\/p>\n
Replacing the O-ring typically requires partially disassembling the relevant arm collector joint or connection point inside the filter tank. Ensure the filter is depressurised and isolated before starting work. Inspect the seating groove for any debris or damage, and fit the new O-ring dry or with a thin layer of silicone lubricant for ease of assembly. Professional installation is recommended for commercial filter systems.<\/p>","protected":false},"excerpt":{"rendered":"
