Value Collection ZBD9500-220 Viton O-ring Dash 220

Product Description

The VALUE COLLECTION ZBD9500-220 is a Dash 220 Viton O-ring with a round cross section, designed for static and dynamic sealing applications across plumbing, hydraulic, pneumatic, and HVAC systems. It measures 1.38 inches inside diameter, 1.63 inches outside diameter, and 0.125 inches thick. The Viton (fluoroelastomer) compound delivers broad chemical resistance and a wide service temperature range from -15 degrees F to 400 degrees F, making it a reliable choice for high-heat and chemically aggressive environments. Hardness is rated at 75 Shore A, which falls in the hard range for consistent seal compression and long service life.

This O-ring is suited for residential and commercial applications where standard Buna-N compounds fall short. Common install scenarios include fuel and oil system fittings, refrigerant-side connections, hot water and steam plumbing joints, and chemical handling equipment. Plumbers, HVAC technicians, and maintenance mechanics working with high-temperature or solvent-exposed assemblies regularly specify Viton compound O-rings for these demanding conditions.

Key Features

• Viton (fluoroelastomer) compound resists fuels, oils, solvents, and refrigerants
• Service temperature range: -15 degrees F to 400 degrees F
• 75 Shore A hardness rating for firm, stable sealing under compression
• Round cross section for consistent groove seating and uniform load distribution
• Dash 220 standard sizing for direct drop-in replacement in AS568-compatible grooves

Compatibility

Designed as a standard AS568 Dash 220 O-ring replacement suitable for any groove or fitting engineered to the Dash 220 cross-section and diameter specification.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or millwrights depending on the application. Depressurize and de-energize the system before removing any fitting or component that retains this O-ring. Lightly lubricate the O-ring with a compatible lubricant before seating to prevent tearing during assembly. Avoid over-stretching the ring onto the groove; if the ring does not seat without force, verify the dash number matches the groove specification.
