Fluidra - Flat Gasket 181 × 112 × 5 mm for PTK 1200 Sand Filter (Ø1000–1200)

Fluidra – Flat Gasket 181 × 112 × 5 mm for PTK 1200 Sand Filter (Ø1000–1200)

This is a genuine Fluidra flat gasket measuring 181 × 112 × 5 mm, designed as a sealing component within the arm collector assembly of the PTK 1200 M/M sand filter in the Ø1000 and Ø1200 mm diameter models. It provides a reliable, pressure-resistant seal between mating surfaces in the filter’s internal pipework or collector arm connections, preventing water bypass and maintaining filtration efficiency.

Compatibility

This gasket is a direct OEM spare part for the Fluidra (AstralPool) PTK 1200 M/M fibre-glass laminated sand filter — specifically the large-diameter Ø1000 mm and Ø1200 mm variants equipped with the arm collector system. These are high-capacity commercial and semi-commercial filters with a 1.2 m filtration bed and a maximum working pressure of 2.5 bar. Always cross-reference your filter’s model number and exploded-view diagram (04963 / 04974) before ordering to confirm fitment.

Why genuine matters

Fluidra OEM gaskets are manufactured to precise dimensional tolerances and from materials suited to continuous pool-water exposure, ensuring a long-lasting, leak-free seal. An ill-fitting or inferior gasket can lead to internal bypass, reduced filtration performance, or pressure-side leaks — particularly critical in large-volume commercial installations operating at elevated pressures.

Installation

Before fitting, clean the mating sealing faces thoroughly and ensure they are free of debris, scale, or old gasket material. The flat profile allows straightforward drop-in replacement with no special tools required, though correct and even torquing of any fasteners is essential to avoid distortion. Professional installation is recommended for pressurised commercial filter systems.
