Not recommended for ketones, hot water or steam in continuous service, and phosphate-ester fluids.\u003c\/p\u003e\u003ch3\u003eYou Can Do This Repair\u003c\/h3\u003e\u003cp\u003eClean the groove and mating surfaces and check them for nicks or burrs. Lubricate the new o-ring, then roll it into the groove without twisting it; pass it over threads or sharp edges on a piece of tape or a plastic sleeve so it is not cut. Tighten to the normal torque. A correct o-ring seals by squeeze, so more torque is not better.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePro Tip:\u003c\/b\u003e A thin coat of \u003ca href=\"https:\/\/beaverislandparts.com\/products\/aqua-flex-food-grade-silicone-lubricant-50g\" target=\"_blank\" rel=\"noopener\"\u003eAqua Flex\u003c\/a\u003e silicone lubricant eases installation, protects the seal on first start-up and extends its life.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eShipping:\u003c\/b\u003e This part is special-ordered and packed for you.

Size, not brand, determines fit for standard o-rings. Measure the old o-ring's inside diameter and cross-section with calipers, or better, measure the groove, because a used ring stretches and flattens. Match the material to the fluid: the right size in the wrong rubber will still fail.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eQ: What is FKM Fluorocarbon good for?\u003c\/b\u003e\u003cbr\u003eA: It is suited to fuels, oils, aromatic hydrocarbons and many acids at high temperature and pressure. Avoid ketones, hot water or steam in continuous service, and phosphate-ester fluids.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eQ: Can I install it myself?\u003c\/b\u003e\u003cbr\u003eA: Yes. Most o-ring replacements take only a pick tool, a clean rag and lubricant. Release pressure, drain the system if needed, remove the old ring, and follow the installation notes above. If it is your first time, take a photo before you take anything apart.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eQ: When will it ship?\u003c\/b\u003e\u003cbr\u003eA: It ships from our facility in about 10 business days, then transits by the carrier service you choose.\u003c\/p\u003e","brand":"Beaver Island Parts Company","offers":[{"title":"4-Pack","offer_id":48854037037261,"sku":"OR.20x2p5.4.BI.MET.V90","price":28.99,"currency_code":"USD","in_stock":true},{"title":"5-Pack","offer_id":48854037070029,"sku":"OR.20x2p5.5.BI.MET.V90","price":29.99,"currency_code":"USD","in_stock":true},{"title":"10-Pack","offer_id":48854037102797,"sku":"OR.20x2p5.10.BI.MET.V90","price":34.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0611\/8110\/0237\/files\/IMG-025_e68b0e22-1f7b-494c-b5f1-c26bbf8689bf.jpg?v=1794356275","url":"https:\/\/beaverislandparts.com\/products\/fkm-fluorocarbon-metric-o-ring-90a-durometer-20mm-id-x-2p5mm-cs","provider":"Beaver Island Parts Company","version":"1.0","type":"link"}
