It measures 3.5 inches inside diameter, 3.75 inches outside diameter, and 0.125 inches thick. NBR compound delivers reliable resistance to petroleum-based fluids, hydraulic oils, and fuels, making this O-ring a dependable sealing solution in demanding fluid-system applications. The 70-durometer hardness rating provides a firm, consistent seal under pressure. Licensed tradespeople working on fluid handling, pneumatic, and hydraulic systems will find this a straightforward replacement or maintenance sealing component.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and commercial plumbing, HVAC refrigerant-adjacent assemblies, hydraulic systems, pneumatic fittings, and general industrial fluid connections where an NBR compound and Dash 238 sizing are specified. Its temperature range of -40 degrees F to 275 degrees F covers a wide range of operating environments encountered in trade service work. It is sold individually with a minimum order quantity of 25 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNitrile butadiene rubber (NBR) construction resists petroleum oils, hydraulic fluids, and fuels\u003c\/li\u003e\n\u003cli\u003eDash 238 standard sizing for straightforward cross-reference and replacement sourcing\u003c\/li\u003e\n\u003cli\u003eRound cross section ensures even seating and consistent radial compression in grooves\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating provides firm seal performance classified as Hard\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 275 degrees F suits a broad range of service conditions\u003c\/li\u003e\n\u003cli\u003eCompact 0.125-inch wall thickness fits standard Dash 238 groove dimensions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 238 O-ring replacement for any application specifying a 3.5-inch ID, 3.75-inch OD, 0.125-inch thick NBR sealing ring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eShut down and depressurize the system fully before removing the old O-ring.
