Mounted on the filter vessel, the sight glass lets operators visually inspect the water flow and clarity during normal filtration and backwash cycles without interrupting operation.<\/p>\n<p>A clear, undamaged sight glass is essential for safe and accurate filter management \u2014 when it becomes clouded, cracked or begins to weep, replacing it with this genuine Fluidra part restores full visibility and maintains vessel integrity.<\/p>\n<h3>Compatibility<\/h3>\n<p>This sight glass assembly is a direct OEM replacement for Fluidra PTK 1200 mm arm-collector sand filters fitted on \u00d8 650 mm and \u00d8 800 mm vessels (assembly references 04949 and 04972). The PTK 1200 filter series is a polyester and fibreglass laminated commercial filter with a 1.2 m filter bed depth. Note that the equivalent successor Delta 1200 filter range shares the same design lineage, but confirm your exact model and assembly reference before ordering.<\/p>\n<h3>Why Genuine Matters<\/h3>\n<p>Genuine Fluidra parts are engineered to the original pressure ratings and dimensional tolerances of the filter vessel. A correctly sealed sight glass maintains the filter&#8217;s operating pressure integrity \u2014 using non-OEM alternatives risks leaks, premature failure and potential safety issues on commercial or high-throughput pool installations.<\/p>\n<h3>Installation<\/h3>\n<p>Installation typically involves draining the filter to below the sight glass port, removing the retaining ring or bolts, swapping the assembly, and resealing. Always inspect the port face and mating gasket surface for damage before fitting. On commercial installations, re-pressurisation and a leak check at working pressure are strongly recommended before returning the system to service.<\/p>","protected":false},"excerpt":{"rendered":"<p>Fluidra &#8211; Sight Glass Assembly for PTK 1200 mm Sand Filter (\u00d8 650\u2013800) This is the genuine Fluidra sight glass assembly (visor assembly) designed for the PTK 1200 mm arm-collector sand filters with tank diameters of 650 mm and 800 mm.
