It is a round metal mesh screen on a rubber base, closer in appearance to screen door mesh than to a filter element.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePicking the right one of three\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003ePentair made three screens to this pattern. They look alike, and the difference is in the dimensions and in the size of the hole through the rubber base, because each is matched to a different tube size. This one measures 1-1\/4 inches in diameter and 7\/8 inch high, with a 1\/4 inch hole that sits fractionally under that. Measuring the screen you pulled out is the fastest way to be certain.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere it is used\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt turns up across a range of filters: Pentair Triton II sand filters in the TR40 through TR140 sizes, the commercial TR100C and TR140C, the Triton C-3, PF stainless steel side mount sand filters, and the Purex CFM and CFW cartridge filters.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":48628784234708,"sku":"PAC-051-1404","price":18.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_d922d99f-cbb9-4ba9-af32-0c240d972e2d.png?v=1788750630","url":"https:\/\/www.activepoolsupply.com\/products\/strainer-air-relief-1-4-before-11-99","provider":"Active Pool Supply","version":"1.0","type":"link"}
