It measures 5\/16 inches inside diameter and 3\/32 inches in thickness, with a durometer rating of 70 Shore A. Buna-N material provides reliable resistance to petroleum-based fluids, hydraulic oils, and moderate temperature ranges, making this O-ring a standard choice for sealing applications across HVAC, plumbing, and general mechanical systems. Installation is performed by licensed technicians and maintenance professionals working on fluid-handling or pneumatic assemblies.\u003c\/p\u003e\u003cp\u003eThis O-ring is suited for use in residential and light commercial applications where a Dash 109 inch-series O-ring is required. Typical use cases include valve stems, fittings, pump housings, and fluid line connections where a reliable static or dynamic face seal is needed. The Buna-N compound performs well in contact with water, oils, and many common refrigerants, making it a versatile replacement seal for trade service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eDash 109 inch-series O-ring for standardized fitment across compatible grooves\u003c\/li\u003e\n\u003cli\u003eNitrile Butadiene Rubber (Buna-N) construction with resistance to petroleum-based fluids and oils\u003c\/li\u003e\n\u003cli\u003eRound cross section for consistent seating and seal integrity\u003c\/li\u003e\n\u003cli\u003e70 Shore A durometer provides a balance of flexibility and compression resistance\u003c\/li\u003e\n\u003cli\u003eInch measurement system for direct replacement in standard US-spec assemblies\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard Dash 109 inch-series replacement O-ring for use in equipment and assemblies requiring a 5\/16 inch inside diameter, 3\/32 inch thick Buna-N seal.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis O-ring is installed by HVAC technicians, plumbers, or mechanical service professionals during valve, pump, or fitting service.
