It measures 5.25 inches inside diameter, 5.625 inches outside diameter, and 0.1875 inches thick with a round cross section. Rated at 90 durometer (extra hard), it delivers firm compression set resistance along with strong tear and abrasion resistance. The temperature range of -40 to 250 degrees F makes it suitable for a broad range of industrial, plumbing, and HVAC service environments. Licensed tradespeople and maintenance technicians working on hydraulic, pneumatic, or fluid systems will find this a direct-fit static or dynamic seal option.\u003c\/p\u003e\u003cp\u003eThis O-ring is used in applications involving petroleum-based fluids, oils, fuels, and hydraulic media. Its Buna-N compound provides excellent resistance to petroleum products, making it a common choice in HVAC compressor fittings, plumbing unions, hydraulic cylinders, and general industrial equipment. The Dash 355 sizing designation is a standard AS568 reference, ensuring cross-compatibility with equipment specifying that dash number. It is not recommended for use in ozone-heavy environments or where prolonged UV exposure is expected. Store away from direct sunlight and ozone-generating electrical equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBuna-N (Nitrile Butadiene Rubber) construction with excellent petroleum product resistance\u003c\/li\u003e\n\u003cli\u003e90 durometer extra-hard rating for strong compression set and abrasion resistance\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section, Dash 355 standard sizing (AS568-compatible)\u003c\/li\u003e\n\u003cli\u003eMeets SAE and MIL-Spec standards\u003c\/li\u003e\n\u003cli\u003eSold in packages of 10 with a minimum order quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with petroleum products and compatible fluid media.

Lubricate the O-ring with a compatible fluid or grease before seating to prevent twisting or pinching during assembly. Avoid stretching the O-ring beyond its design limits during installation. Do not install in grooves with sharp edges that could cut or nick the elastomer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Buna-N (Nitrile Butadiene Rubber)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash Number\u003c\/strong\u003e: 355\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 5.25 inches (132.72 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 5.625 inches (142.87 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (5.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCross Section Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness\u003c\/strong\u003e: 90 Durometer (Extra 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 Media\u003c\/strong\u003e: Petroleum Products\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFDA Approved\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE, MIL-Spec\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.26 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31401503\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: ZMSCH90355\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51714112094514,"sku":"ZMSCH90355","price":17.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/11b8653e296cd53d9586459ce83ba4a7.jpg?v=1788496383","url":"https:\/\/voomisupply.com\/products\/value-collection-zmsch90355-o-ring-dash-355-nitrile-90a","provider":"Voomi Supply","version":"1.0","type":"link"}
