The cold flow characteristics of PTFE are used to full advantage in reducing the extrusion gaps to a minimum and allowing automatic compensation for wear. High resistance to virtually all chemicals, low friction and wear rates render PTFE as the ideal material for anti-extrusion devices. The spiral backup ring is the most common style in use being effectively self-adjusting to diametral tolerances.\u003cbr\u003e\n\u003c\/p\u003e","brand":"Simply PTFE O-Ring","offers":[{"title":"Default Title","offer_id":54116899651925,"sku":"BKS0186-24","price":4.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/1491\/3109\/files\/bks0186.jpg?v=1785335558","url":"https:\/\/simplybearings.us\/products\/bks0186-24","provider":"Simply Bearings Ltd - Ball Bearings, Oil Seals, O-rings, V-Belts, SKF","version":"1.0","type":"link"}
