Value Collection ZMSCV70140 Viton O-ring Dash 140

Product Description

The VALUE COLLECTION ZMSCV70140 is a Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in systems that handle petroleum products, high-temperature fluids, and chemically aggressive media. It carries a Dash 140 designation, an inside diameter of 2.25 inches, an outside diameter of 2.438 inches, and a cross-section thickness of 0.094 inches. The durometer hardness rating is 70, placing it in the hard range for reliable sealing under pressure. Plumbers, HVAC technicians, and fluid-system mechanics install this type of seal in valves, fittings, pumps, and manifolds where standard nitrile or EPDM compounds fall short.

This O-ring is suited for use in hydraulic, pneumatic, and fuel-handling systems that require resistance to petroleum-based fluids and elevated operating temperatures. Its fluoroelastomer compound handles continuous service up to 400 degrees F and remains functional down to -15 degrees F, making it appropriate for both industrial and commercial HVAC or refrigeration-adjacent fluid circuits. The round cross section provides consistent sealing contact in standard O-ring grooves. It is sold in a package quantity of 10, with a minimum order quantity of 1 package.

Key Features

• Fluoroelastomer (Viton) compound offers good resistance to petroleum products and fuels
• Wide operating temperature range: -15 degrees F to 400 degrees F
• Durometer hardness of 70 (hard rating) supports low compression set under load
• Low gas permeability makes it suitable for vacuum service applications
• Wide spectrum of chemical compatibility beyond petroleum-based fluids
• Round cross section fits standard Dash 140 O-ring grooves

Compatibility

Designed as a standard Dash 140 O-ring replacement for any groove or fitting that accepts a 2.25-inch ID fluoroelastomer seal; compatible with systems handling petroleum products where Viton-grade material is specified.

Installation Notes

Power down or depressurize the system fully before removing the old O-ring and installing the replacement. Inspect the groove for nicks, corrosion, or debris that could compromise the sealing surface. Apply a thin film of compatible lubricant to the O-ring before seating it to prevent pinching or rolling during assembly. This work is typically performed by licensed plumbers, HVAC technicians, or fluid-system mechanics following applicable service procedures for the equipment involved.
