Value Collection ZMSCV70260 Viton O-ring Dash 260

Product Description

The VALUE COLLECTION ZMSCV70260 is a Dash 260 Viton (fluoroelastomer) O-ring with a round cross section, sized at 6.5 inches inside diameter, 6.75 inches outside diameter, and 0.125 inches thick. Rated to a Shore A hardness of 70 and built for a working temperature range of -15 degrees F to 400 degrees F, this O-ring is engineered for demanding sealing applications involving petroleum products, high heat, and chemical exposure. Its low compression set and low gas permeability make it a reliable choice for static and dynamic sealing tasks across HVAC, plumbing, and industrial fluid systems. Licensed trades and industrial maintenance technicians are the typical installers.

This O-ring suits applications where petroleum-based fluids, high temperatures, or a wide spectrum of chemical media are present. Common install scenarios include pump housings, valve bodies, flanged connections, and compressor fittings in commercial and light industrial settings. It is also suitable for vacuum service applications where low gas permeability is critical. The fluoroelastomer compound provides chemical compatibility well beyond standard Buna-N or EPDM materials, making it appropriate where those compounds would degrade prematurely.

Key Features

• Fluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F
• Shore A hardness of 70 for a firm, reliable compression seal
• Low compression set maintains seal integrity under prolonged load
• Good resistance to petroleum products and a wide spectrum of chemicals
• Low gas permeability makes it suitable for vacuum service
• Round cross section, Dash 260 standard sizing for straightforward groove matching

Compatibility

Designed as a standard Dash 260 O-ring replacement for grooves accepting a 6.5-inch inside diameter, 6.75-inch outside diameter, and 0.125-inch cross-section seal in applications involving petroleum products or elevated temperatures.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Always depressurize and isolate the system before removing the existing seal, and confirm the groove dimensions match the Dash 260 specification before installation. Apply a compatible O-ring lubricant sparingly to ease seating and prevent pinching or rolling during assembly. Do not stretch the O-ring beyond its natural elasticity or use sharp tools that could nick the sealing surface.
