It measures 0.171 inches inside diameter, 0.340 inches outside diameter, and 0.047 inches thick, with a rectangular cross-section profile. The medium hardness rating of 55 durometer provides a firm, low-compression-set seal suitable for demanding fluid and gas sealing applications. Rated for service from -65 degrees F to 500 degrees F, this O-ring handles extreme temperature swings that would degrade standard nitrile or EPDM compounds. PTFE material also delivers broad chemical resistance. HVAC technicians, plumbers, and industrial maintenance professionals use these in high-temperature or chemically aggressive sealing points.\u003c\/p\u003e\u003cp\u003eThis O-ring is appropriate for static and low-dynamic sealing applications where standard elastomeric compounds are not suitable. Typical uses include sealing fittings, valve stems, instrument connections, and fluid-handling assemblies in HVAC refrigeration circuits, chemical process lines, and high-temperature plumbing systems. The Dash 007 designation conforms to standard AS568 sizing, making cross-referencing straightforward. Each pack contains 50 pieces, which suits service trucks and shop stock where small-profile O-rings are consumed in quantity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePTFE construction offers broad chemical resistance and a wide service temperature range of -65 degrees F to 500 degrees F\u003c\/li\u003e\n\u003cli\u003eDash 007 AS568-standard sizing for straightforward cross-referencing and replacement\u003c\/li\u003e\n\u003cli\u003eRectangular cross-section profile for consistent seating in standard O-ring grooves\u003c\/li\u003e\n\u003cli\u003e55 durometer medium hardness provides firm compression with reliable low-leak sealing\u003c\/li\u003e\n\u003cli\u003ePack of 50 units supports bench stock and field service inventory\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.01 pounds per pack, easy to stock in quantity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 007 AS568-size replacement O-ring for static and low-dynamic sealing applications in HVAC, plumbing, and fluid-handling systems where PTFE material is specified.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician following applicable system lockout and pressure-relief procedures before any seal is broken. Ensure the mating groove is clean and free of debris before seating the O-ring. Do not use petroleum-based lubricants with PTFE O-rings unless confirmed compatible with system fluids.
