Value Collection ZBD9500-138 Viton O-ring Dash 138

Product Description

The VALUE COLLECTION ZBD9500-138 is a Dash 138 Viton O-ring designed for static and dynamic sealing applications across a wide range of industrial and mechanical systems. With a 2.13-inch inside diameter, a 2.31-inch outside diameter, and a 0.094-inch cross-section thickness, this round-profile O-ring delivers consistent compression sealing. The Viton (FKM) compound gives it strong resistance to petroleum-based fluids, hydraulic oils, fuels, and elevated temperatures. Rated for a working temperature range of -15 degrees F to 400 degrees F, it holds its seal integrity where standard rubber compounds fail. A 75 Shore A hardness rating places it in the hard range, making it well-suited for higher-pressure sealing scenarios. HVAC technicians, plumbers, and industrial mechanics routinely specify Viton O-rings in service calls and equipment overhauls.

This O-ring is used wherever a Dash 138 cross-section and Viton material are required by equipment specification or OEM design. Common applications include pump housings, valve stems, hydraulic fittings, refrigerant service ports, and fuel system components. Its temperature resistance makes it a preferred choice over BUNA-N or EPDM compounds in environments exposed to elevated heat, aggressive chemicals, or petroleum-based media. This item is sold in single-unit packaging with a minimum order quantity of 10 units.

Key Features

• Viton (FKM) compound resists petroleum fluids, hydraulic oils, fuels, and high-heat environments
• Working temperature range: -15 degrees F to 400 degrees F
• 75 Shore A hardness rating — suitable for higher-pressure sealing applications
• Round cross-section profile for consistent compression seal
• Dash 138 designation ensures dimensional interchangeability with OEM specifications
• Not FDA approved — intended for industrial and mechanical service, not food-contact applications

Compatibility

Designed as a standard Dash 138 O-ring replacement for any application specifying a 2.13-inch ID, 2.31-inch OD, 0.094-inch thickness Viton seal in pump, valve, hydraulic, or refrigerant service assemblies.

Installation Notes

O-ring installation should be performed by a qualified technician following the equipment manufacturer's service procedures. Always de-energize and depressurize the system before removing old seals. Inspect the groove and mating surfaces for scoring or debris before seating the new O-ring. Lightly lubricating the O-ring with a compatible fluid or grease prior to installation reduces the risk of tearing during assembly.
