Value Collection ZBD9500-207 Viton O-ring Dash 207

Product Description

The VALUE COLLECTION ZBD9500-207 is a Dash 207 Viton O-ring with a round cross section, designed for static and dynamic sealing applications across plumbing, HVAC, hydraulic, and industrial fluid systems. The inside diameter measures 0.56 inches, outside diameter 0.81 inches, and thickness 0.125 inches. Made from Viton fluoroelastic material, this O-ring is rated for service from -15 degrees F to 400 degrees F, making it suitable for high-heat and chemically aggressive environments where standard Buna-N seals fall short. Durometer hardness is rated at 75, placing it in the hard hardness range for reliable compression set resistance under sustained pressure.

This O-ring is used wherever a Dash 207 profile is called for in fluid and gas sealing assemblies. Common applications include HVAC refrigerant fittings, hydraulic cylinder end caps, valve stems, pump housings, and plumbing connections exposed to oils, fuels, or elevated temperatures. Viton compound is the preferred choice when the service environment involves petroleum-based fluids, synthetic lubricants, or high continuous operating temperatures that would degrade standard elastomers.

Key Features

• Viton fluoroelastic material rated from -15 degrees F to 400 degrees F continuous service
• Dash 207 standard sizing: 0.56 inches ID, 0.81 inches OD, 0.125 inches thick
• Round cross section for uniform compression in standard O-ring grooves
• 75 durometer hardness for resistance to extrusion and compression set
• Compatible with petroleum-based oils, fuels, and many synthetic fluids

Compatibility

Designed as a standard Dash 207 O-ring replacement for any groove or fitting specified to accept a 0.56 inches ID by 0.81 inches OD by 0.125 inches thick round cross-section seal in Viton material.

Installation Notes

O-ring installation should be performed by a licensed plumber, HVAC technician, or qualified mechanic, depending on the system type. Depressurize and isolate the assembly before removing the old seal. Lightly lubricate the O-ring with a compatible fluid or grease before seating to prevent tearing during installation. Inspect the groove for burrs or corrosion that could damage the new seal or cause a leak path.
