It provides a secure, leak-free pipe connection on the filter&#8217;s plumbing circuit and allows the pipework to be disconnected quickly without cutting or dismantling the surrounding installation.<\/p>\n<h3>Compatibility<\/h3>\n<p>This 3-piece union is a direct OEM spare part for the Fluidra PTK ARM filter assemblies with 1,000 mm filter bed height, covering tank diameters of 650 mm, 800 mm and 950 mm. Always verify your filter model and connection size against the Fluidra spare parts diagram before ordering to ensure a correct fit.<\/p>\n<h3>Why Genuine Matters<\/h3>\n<p>Genuine Fluidra components are manufactured to match the exact bore, thread pitch and sealing surfaces of the original installation. An off-spec union on a commercial sand filter operating at up to 250 kPa can result in leaks, pressure loss and costly downtime. Using the OEM part protects both the filter and the wider pool system.<\/p>\n<h3>Installation<\/h3>\n<p>The three-part design \u2014 consisting of two spigot ends and a locking collar \u2014 allows straightforward hand-tightened assembly with no specialist tools required. Ensure all mating surfaces are clean and that the integral sealing ring is correctly seated before tightening. On pressurised commercial systems, installation should be carried out by a qualified pool technician.<\/p>","protected":false},"excerpt":{"rendered":"<p>Fluidra &#8211; 3-Piece Union Connection 75 mm for PTK ARM Sand Filter This is the genuine Fluidra 3-piece union connection in 75 mm diameter, designed as a replacement fitting for the PTK ARM commercial sand filter series.
