Fluidra - Filter Sight Glass with Gasket for PTK 1200 mm Arm Filters (Ø650–800)

Fluidra – Filter Sight Glass with Gasket for PTK 1200 mm Arm Filters (Ø650–800)

This is the genuine Fluidra replacement sight glass (inspection window) complete with sealing gasket, designed for the PTK 1200 mm arm-type commercial sand filters in 650 mm and 800 mm tank diameters. The sight glass allows operators to visually monitor water flow and filter condition without opening the vessel, while the included gasket ensures a pressure-tight, leak-free seal around the viewing port.

Compatibility

This part is a direct OEM spare for the Fluidra PTK 1200 mm arm filter series, specifically the Ø650 and Ø800 mm models. The PTK 1200 mm series is a 1.2-metre filter bed commercial laminated fibreglass sand filter range; the successor Delta 1200 filter is considered equivalent to the PTK 1200 series and shares design lineage. Always verify your filter’s model number and part reference before ordering.

Why Genuine Matters

Fluidra PTK commercial filters operate under significant pressure, and a poorly fitting sight glass or degraded gasket can lead to leaks or failure of the inspection port seal. Using a genuine Fluidra part guarantees correct dimensions, compatible EPDM-grade sealing material, and compliance with the filter’s original engineering tolerances — keeping your installation safe and your warranty intact.

Installation

The sight glass assembly threads or seats into the designated port on the filter body. Always depressurise and isolate the filter before replacing the sight glass. Inspect the seating surface for damage before fitting, hand-tighten initially and then secure to the manufacturer’s torque specification to avoid cracking the viewing window. Professional installation is recommended for commercial filter systems.
