PSH - Drain Plug with Gasket 1/4" BSP – Great Giant Pre-filter - 4180112R

PSH – Drain Plug with Gasket 1/4″ BSP – Great Giant Pre-filter

This is the genuine PSH replacement drain plug with gasket for the Great Giant series pre-filter, corresponding to position 68 in the official exploded-view diagram. The 1/4″ BSP-threaded plug seals the drain port on the pre-filter body, allowing quick and controlled draining during routine maintenance, winterisation, or servicing. Supplied as a single unit complete with its mating gasket for a leak-free seal.

Compatibility

Designed exclusively for PSH Giant-series pre-filters (Prefiltros Serie Giant), including the Great Giant model. Always cross-reference the exploded-view diagram at position 68 and confirm your pre-filter model before ordering, as this plug is not interchangeable with other thread standards or PSH product families.

Why Genuine Matters

Genuine PSH parts are manufactured to exact thread tolerances and material specifications for the Giant pre-filter housing. An incorrect or aftermarket plug risks cross-threading, seal failure, or water leakage at the drain port — issues that can disrupt filtration and potentially damage surrounding components. This original part ships with a matched gasket, eliminating the need for improvised sealing solutions such as PTFE tape.

Installation

Remove the old or damaged plug by unscrewing it from the 1/4″ BSP drain port on the pre-filter body. Fit the new gasket onto the plug and thread it in by hand before tightening firmly — do not over-torque. No PTFE tape is required when the gasket is in good condition. Always depressurise and drain the system before beginning work.
