This round-section elastomer seal is rated for a working temperature range of -40 degrees F to 250 degrees F and carries a hardness rating of 70 Shore A. It is sold in a package quantity of 25 rings. HVAC technicians, plumbers, and industrial maintenance professionals install this O-ring as a static or dynamic face seal in fluid and gas systems where petroleum-based media are present.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for residential and commercial applications involving hydraulic systems, refrigeration service ports, compressor fittings, fuel systems, and general plumbing connections where petroleum-product compatibility is required. Its Buna-N compound makes it the most widely used elastomer in fluid-sealing applications. The 25-piece packaging is appropriate for technicians servicing multiple units or stocking a service van.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBuna-N (NBR) compound offers excellent resistance to petroleum products including oils, fuels, and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness with a hard hardness rating for reliable compression set performance\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile for consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n  \u003cli\u003eSold in a 25-piece package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with petroleum products and compatible fluids.
