“Nyl-End” sump strainers (Style P) are made with the same selection of stainless steel elements as the standard all-metal units. They differ in that the connector end pieces are molded in a single piece of glass reinforced nylon resin. Pleated stainless elements are epoxy bonded in place. Theyre as serviceable as all-metal units, but they cost 12 to 50 percent less, depending on size.
