It measures 0.468 inches inside diameter, 0.624 inches outside diameter, and 0.078 inches thick with a round cross section. The silicone compound provides a wide service temperature range of -80 degrees F to 450 degrees F, making it suitable for dry heat, weather, and ozone-exposed environments. Hardness is rated at 70 Shore A. This listing is sold as a pack of 50 rings. Plumbers, pipefitters, HVAC technicians, and industrial maintenance trades install this style of fitting seal routinely.\u003c\/p\u003e\u003cp\u003eThis O-ring is intended for boss-port sealing on straight-thread hydraulic and fluid fittings across residential, commercial, and light industrial plumbing and HVAC piping systems. The silicone material offers good resistance to oils, chemicals, and solvents, though oil resistance is limited and should be evaluated against specific system fluid compatibility before installation. It is well suited for applications requiring reliable sealing across wide temperature swings, including outdoor-exposed or high-heat equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 906 silicone O-ring for straight-thread tube fitting boss ports\u003c\/li\u003e\n\u003cli\u003eService temperature range: -80 degrees F to 450 degrees F\u003c\/li\u003e\n\u003cli\u003eRound cross section, 0.078 inches thick (5\/64 inch nominal)\u003c\/li\u003e\n\u003cli\u003e70 Shore A hardness rating\u003c\/li\u003e\n\u003cli\u003eCompatible with oils, chemicals, and solvents; limited oil resistance noted\u003c\/li\u003e\n\u003cli\u003eGood weather and ozone resistance for outdoor or exposed installations\u003c\/li\u003e\n\u003cli\u003ePack quantity of 50 rings per order\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service seal for straight-thread tube fitting boss ports requiring a Dash 906 silicone O-ring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDepressurize and drain the system before removing or replacing any fitting seals. Inspect the boss port seat for nicks or corrosion that could prevent a proper seal.
