Value Collection ZMSCV70270 Viton O-ring Dash 270

Product Description

The VALUE COLLECTION ZMSCV70270 is a Dash 270 Viton O-ring engineered for sealing applications that demand resistance to high temperatures and petroleum-based fluids. Manufactured from fluoroelastomer compound at 70 Shore A hardness, this O-ring measures 9 inches inside diameter, 9.25 inches outside diameter, and 0.125 inches thick with a round cross section. The fluoroelastomer material delivers low compression set, high temperature resistance up to 400 degrees F, and low gas permeability, making it a reliable choice for demanding static and dynamic sealing tasks. Plumbers, HVAC technicians, and industrial maintenance professionals install this part in systems where standard nitrile or EPDM seals are insufficient.

This O-ring is suited for residential and commercial applications involving petroleum-based media, hydraulic systems, fuel handling lines, and high-temperature fluid circuits. The Dash 270 designation conforms to standard AS568 sizing, allowing straightforward identification and replacement. Its chemical compatibility extends across a wide spectrum of hydrocarbons, making it appropriate for use in pumps, valves, flanges, and fittings where sealing integrity under elevated temperature and pressure cycling is required. The package includes 2 O-rings per unit.

Key Features

• Fluoroelastomer (Viton) construction resists petroleum products, fuels, and hydraulic fluids
• Rated for service from -15 degrees F to 400 degrees F
• 70 Shore A hardness rating provides a firm, low-compression-set seal
• Round cross section with 0.125 inch thickness suits standard gland geometries for Dash 270 sizing
• Low gas permeability supports vacuum service applications
• Wide chemical compatibility across petroleum-based and many synthetic fluid environments

Compatibility

Designed as a standard AS568 Dash 270 replacement O-ring compatible with petroleum products and systems requiring fluoroelastomer sealing material. Verify gland dimensions against the 9 inch ID, 9.25 inch OD, and 0.125 inch cross section before installation.

Installation Notes

Depressurize and drain the system fully before removing the existing O-ring to prevent fluid release or injury. Clean the seating groove of debris and inspect for damage that could compromise the seal. Lubricate the O-ring with a compatible fluid or grease before seating to avoid tearing during assembly. Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance technicians following applicable system service procedures.
