Designed for use in a wide variety of sealing applications, this neoprene O-ring meets standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings. Neoprene (polychloroprene) can have a high tensile strength, and has abrasion, tear, and compression set resistance. It is generally fire resistant and compatible for use with ozone, sunlight, ammonia, Freon, and some hydrocarbons. It also had good adhesion to metal and is often used in metal to rubber bonding applications. Neoprene is vulnerable to ketones, acids, brake fluids and phosphate esters. The durometer hardness of this neoprene O-ring is 70A. Durometers measure the hardness of a material and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation. On a scale of 0 to 100, a value of 0 indicates that a sample was completely penetrated, while a value of 100 shows no indentation in the sample. The letter following the number identifies the shore scale, which i\u003c\/p\u003e\u003cp\u003eFree shipping included. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43357769793745,"sku":"BW-B0053UZQ2Y","price":24.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/61xgh9zbKlL._SL1498_d06298df-64ed-41b4-a0e0-751bd0513b0e.jpg?v=1790985947","url":"https:\/\/belmontwarehouse.com\/products\/261-neoprene-o-ring-70a-durometer-round-black-6-3-4-id-7-od-1-8-width-pack-of-8","provider":"Belmont Warehouse","version":"1.0","type":"link"}
