Value Collection ZMSCV70911 Viton O-ring Dash 911

Product Description

The VALUE COLLECTION ZMSCV70911 is a Dash 911 Viton O-ring designed for use as an O-ring boss gasket on straight-thread tube fittings. Made from fluoroelastomer (Viton) with a Shore hardness of 70, it delivers reliable sealing performance across a wide temperature range of -15 degrees F to 400 degrees F. The round cross-section measures 0.863 inches inner diameter, 1.095 inches outer diameter, and 0.116 inches thick. Black in color, this O-ring suits licensed plumbers, HVAC technicians, and pipefitters working with fluid and gas systems that demand chemical-resistant sealing components.

This O-ring is suited for use in hydraulic, pneumatic, and fluid-handling systems where petroleum product exposure is common. The fluoroelastomer compound provides good resistance to petroleum products, low compression set, and high-temperature resistance, making it appropriate for both residential and commercial service applications. It also performs well in vacuum service environments and offers low gas permeability, making it a reliable choice for straight-thread boss port connections in tight-tolerance assemblies.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Shut off all system pressure and fluid supply before removing or installing O-rings. Inspect the boss port seat and fitting threads for nicks or debris before seating the O-ring. Do not over-torque the fitting, as this can damage the sealing surface and compromise the O-ring.
