It measures 9.75 inches inside diameter by 10.125 inches outside diameter with a 0.1875-inch cross-section thickness and a round cross-section profile. Rated at 70 Shore A hardness, this O-ring handles operating temperatures from -40 degrees F to 250 degrees F and is compatible with petroleum-based fluids and lubricants. Licensed plumbers, pipefitters, and maintenance technicians install this size for larger-diameter piping flanges, pump housings, and valve assemblies where a reliable NBR seal is required.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for residential and commercial applications involving petroleum products, hydraulic oils, and water-based fluids in moderate-temperature environments. Typical installations include large-bore pump covers, filter housings, and flange face seals in HVAC hydronic systems, industrial plumbing, and fluid-handling equipment. It conforms to SAE and MIL-Spec standards, making it appropriate for both commercial maintenance and light industrial service work. Sold in a package quantity of 5, it is well suited for service techs who need on-hand spares for repeat-call equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNitrile Butadiene Rubber (Buna-N) construction offers excellent resistance to petroleum products, hydraulic fluids, and lubricating oils\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating provides strong compression set resistance and durability under sustained clamping loads\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F covers most HVAC, plumbing, and light industrial service conditions\u003c\/li\u003e\n\u003cli\u003eRound cross-section profile ensures consistent seating in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003eConforms to SAE and MIL-Spec standards for broad application acceptance\u003c\/li\u003e\n\u003cli\u003eResistant to tear and abrasion, extending service intervals in dynamic or high-vibration installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with petroleum products and petroleum-based hydraulic fluids.

Depressurize and drain the system completely before removing the existing O-ring or disassembling any joint. Inspect the groove for nicks, corrosion, or debris before seating the new O-ring, and apply a compatible lubricant to ease installation and prevent roll or twist. Do not store NBR O-rings in direct sunlight or near motors and electrical equipment that may generate ozone, as ozone exposure degrades the elastomer over time.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 9.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 10.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness (Cross Section)\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 376\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nitrile Butadiene Rubber (Buna-N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 70 Shore A (Hard)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Fluids\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ZMSCH70376\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51733357297970,"sku":"ZMSCH70376","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d07c30dd8efcd500b8bb1759bdfbae86_649b1fe8-37b8-433f-8e34-88fdbf4852dd.jpg?v=1788754615","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch70376-o-ring-dash-376-nbr-9-75-in-id","provider":"Voomi Supply","version":"1.0","type":"link"}
