PSH – 1/2″ BSP Brass Drain Plug for FDN Series Cast Iron Pre-filter

This genuine PSH brass drain plug (1/2″ BSP / Gas thread) is the factory-specified blanking plug for the PSH FDN series cast iron pre-filters, corresponding to position 69 on the official exploded-view diagram. It seals the drain port on the pre-filter housing, allowing controlled drainage during maintenance, servicing, or winter shut-down.

Kompatibilität

This plug is designed exclusively for PSH FDN series cast iron pre-filters, covering models in the DN-1500 and DN-3000 range. Always cross-reference against your unit’s exploded-view diagram (position 69) before ordering to confirm fitment with your specific pre-filter assembly.

Warum Echtheit zählt

The PSH FDN series is built from cast iron with specialist coatings for long-term durability in demanding commercial pool environments. Using a genuine PSH brass plug ensures correct 1/2″ BSP thread engagement and a leak-free seal, avoiding the risk of cross-threading or pressure loss that can result from aftermarket alternatives. Brass construction resists corrosion and is well-suited to the wet, chemically-active environment of pool pre-filter housings.

Installation

Isolate and depressurise the pre-filter system before removing or fitting the plug. Apply a suitable thread sealant or PTFE tape to the BSP threads and tighten to the torque appropriate for a 1/2″ brass fitting in a cast iron body. If the housing threads show signs of corrosion, clean them before installation. Sold individually.
