The VALUE COLLECTION ZMSCV70310 is a Dash 310 Viton (fluoroelastomer) O-ring sold in a pack of 10. It measures 0.500 inches inside diameter, 0.875 inches outside diameter, and 0.1875 inches thick with a round cross section. Shore hardness is 70, placing it in the hard rating category. Fluoroelastomer construction provides strong resistance to petroleum products, high-temperature service up to 400 degrees F, low compression set, and low gas permeability. Licensed plumbers, HVAC technicians, and industrial maintenance technicians install this type of O-ring as a static or dynamic seal in fluid and gas systems.
This O-ring is suited for applications involving petroleum-based fluids, hydraulic systems, fuel systems, vacuum service lines, and similar environments where chemical compatibility and temperature stability are critical. The Dash 310 designation follows the AS568 standard sizing series, making it a recognized size across a wide range of fluid-handling and mechanical equipment. It performs reliably from -15 degrees F to 400 degrees F, covering most residential and light commercial HVAC, plumbing, and industrial service scenarios. Each package contains 10 O-rings to support service calls requiring multiple replacements or to stock a service vehicle.
Designed as a standard AS568 Dash 310 replacement O-ring for use with petroleum products and compatible fluids in fluid-handling, hydraulic, fuel, and vacuum service applications. Verify groove dimensions and system fluid compatibility before installation.
Install this O-ring in a clean, properly sized groove free of burrs, nicks, or debris. Shut off all fluid supply and depressurize the system fully before replacing any O-ring seal. Apply a compatible lubricant sparingly to ease installation and prevent twisting; use only lubricants rated for fluoroelastomer and the system fluid present. A licensed technician should verify that the replacement O-ring meets the pressure and chemical requirements of the specific system before returning it to service.
