Product overview

The Air Relief Plug, Replacement for Astral Filters is an aftermarket air relief valve built to replace the original component in Astral filtration systems. In service it purges trapped air from the top of the filter tank so the vessel fills completely with water. This is a consumable in practice: the stem seizes and the seal leaks, which is both a nuisance drip and a safety concern on a pressure vessel.
