The VALUE COLLECTION BDKP77897 is a Dash 012 O-ring with a round cross section and a thickness of 1/16 inch. O-rings of this type create static or dynamic fluid seals at joints, fittings, and valve stems across a wide range of systems. The round cross-section profile seats evenly in standard grooves, providing reliable leak prevention under pressure. This listing covers a pack of 10 individual O-rings, making it a practical choice for technicians who service multiple units or need spares on hand. Licensed plumbers, HVAC technicians, and industrial maintenance professionals regularly stock Dash 012 O-rings as a common replacement size.
Dash 012 O-rings are used in residential and light commercial applications including refrigerant circuit fittings, water supply connections, pneumatic line fittings, and hydraulic valve assemblies. Their compact size makes them well-suited for small-diameter ports and fittings commonly found in HVAC equipment, plumbing fixtures, and fluid-handling components. The 10-piece pack supports bench stock replenishment for shops and field service vans where this dash size sees regular turnover.
Designed as a standard Dash 012 replacement O-ring for use in plumbing, HVAC, pneumatic, and hydraulic fittings that accept a round cross-section O-ring of this dash size and thickness.
Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and, where applicable, evacuate or drain the system before removing any fitting or valve that retains this O-ring. Inspect the groove and mating surfaces for nicks or corrosion before seating the new O-ring. Follow applicable code requirements such as IPC or IFGC when reinstating pressurized lines to service.
