The gasket does the actual sealing, not the collar. This one has a T shaped section: the stem locates in the groove so the gasket cannot creep out of position, and the flange is squeezed between the two faces as the collar is tightened.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen to replace it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eUnion gaskets harden, flatten and take a set. The symptom is a union that keeps weeping no matter how hard the collar is turned, and the common mistake is to keep turning. That splits collars and does nothing for the leak. Fit a new gasket, tighten by hand until it just stops, and the joint seals. Because unions get opened every time a pump comes off the pad, it is worth keeping a spare.\u003c\/p\u003e","brand":"CMP","offers":[{"title":"Default Title","offer_id":48635038728404,"sku":"CTM-851-0008","price":4.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_d33be36d-fe7d-45e9-ad31-6d3ce2fab4d0.png?v=1788840308","url":"https:\/\/www.activepoolsupply.com\/products\/2in-union-t-gasket","provider":"Active Pool Supply","version":"1.0","type":"link"}
