It measures 5.5 inches inside diameter, 5.875 inches outside diameter, and 0.1875 inches thick. Rated at 70 Shore A hardness, this O-ring is designed for static and dynamic sealing applications where petroleum-based fluids are present. It carries SAE and MIL-Spec standards compliance and operates across a temperature range of -40 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and fluid-system technicians typically install this part in industrial and commercial fluid-handling equipment.\u003c\/p\u003e\n\u003cp\u003eThis O-ring is suited for sealing applications involving petroleum products, hydraulic fluids, and mineral oils in plumbing, HVAC, and general industrial systems. Its large diameter makes it appropriate for flanged connections, large-bore fittings, pump housings, or valve assemblies where a robust seal is required. The pack quantity of 5 supports service calls requiring multiple replacements or stocking common seal sizes on a service vehicle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNitrile Butadiene Rubber (Buna-N) compound provides excellent resistance to petroleum products and hydraulic fluids\u003c\/li\u003e\n  \u003cli\u003e70 Shore A hardness rating offers strong compression set resistance and tear and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003eRound cross-section profile ensures consistent seating in standard O-ring grooves\u003c\/li\u003e\n  \u003cli\u003eRated for temperatures from -40 degrees F to 250 degrees F for broad service range\u003c\/li\u003e\n  \u003cli\u003eMeets SAE and MIL-Spec standards for verified dimensional and material compliance\u003c\/li\u003e\n  \u003cli\u003ePack of 5 units per package with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with petroleum products, hydraulic fluids, and mineral oils.
