Offering greater filtering capacity than ARG or SA models, these strainers feature an improved strainer basket and a design that secures the basket under all flow conditions. Upper and lower assemblies are quality cast bronze, with the stainless steel filter basket housed within a Lucite sight glass for easy inspection. Cast bronze wingnut permits easy strainer removal for cleaning and a plug at the bottom enables draining for winterization. O-rings seal all mating surfaces and flanges on one side permit bulkhead mounting. One year warranty.
