Anywhere a union collar screws down on this size of connection, this is the seal that does the work.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy it matters\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eOn the discharge side a tired union o-ring drips. On the suction side it does something worse: it lets air in, so the pump loses prime and the basket fills with air instead of water. Either symptom at a union points at the o-ring first.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFitting it\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWipe the groove clean, lubricate the new o-ring, and tighten the union collar by hand. Union collars are not meant to be pulled up with a wrench, and overtightening cracks the collar without improving the seal.\u003c\/p\u003e","brand":"Sta-Rite","offers":[{"title":"Default Title","offer_id":48628828668116,"sku":"STA-061-5823","price":9.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/9568\/2516\/files\/default_17698451-9d84-4287-9785-8b4676728b85.png?v=1788753487","url":"https:\/\/www.activepoolsupply.com\/products\/o-ring-1-1-2-2","provider":"Active Pool Supply","version":"1.0","type":"link"}
