Value Collection ZBD9500-139 Viton O-ring Dash 139

Product Description

The VALUE COLLECTION ZBD9500-139 is a Viton O-ring with a round cross section, sized to Dash 139 standards. It features an inside diameter of 2.1875 inches, an outside diameter of 2.38 inches, and a thickness of 0.0937 inches. Manufactured from Viton fluoroelastic material, this O-ring delivers strong resistance to heat, fuels, hydraulic fluids, and a wide range of chemicals. It carries a hardness rating of 75 Shore A, placing it in the hard durometer range. Licensed tradespeople and maintenance technicians working with fluid handling, pneumatic, or mechanical sealing systems will find this a reliable replacement or service part.

This O-ring is suited for static and dynamic sealing applications across HVAC, plumbing, industrial fluid systems, and hydraulic assemblies where elevated temperatures or chemical exposure are present. The Viton compound supports continuous service between -15 degrees F and 400 degrees F, making it appropriate for demanding environments where standard nitrile or EPDM compounds would degrade. It ships individually but carries a minimum order quantity of 10 units.

Key Features

• Viton fluoroelastic material resists fuels, oils, hydraulic fluids, and many solvents
• Operating temperature range from -15 degrees F to 400 degrees F
• Round cross section profile for consistent sealing contact
• 75 Shore A hardness for firm, reliable compression under load
• Conforms to Dash 139 standard sizing for straightforward cross-referencing
• Lightweight at 0.01 pounds per unit

Compatibility

Designed as a standard Dash 139 O-ring replacement for grooves and fittings dimensioned to accept a 2.1875-inch ID by 2.38-inch OD by 0.0937-inch thick round-cross-section seal in Viton material.

Installation Notes

Installation should be performed by a qualified technician familiar with the system being serviced. Depressurize and isolate the assembly before removing the old O-ring, and clean the groove thoroughly to remove debris or old sealing compound. Lightly lubricate the O-ring with a compatible fluid or grease before seating to avoid tearing during installation. Do not use petroleum-based lubricants on Viton O-rings unless confirmed compatible with the system media.
