Value Collection ZMSCV70273 Viton O-ring Dash 273

Product Description

The VALUE COLLECTION ZMSCV70273 is a Dash 273 Viton fluoroelastomer O-ring used to create a reliable static or dynamic seal in fluid and gas systems. With a 9.75-inch inside diameter, 10-inch outside diameter, and 0.125-inch cross-section thickness, this O-ring seats in standard Dash 273 grooves. The round cross-section profile ensures consistent compression and low leakage across a wide service temperature range of -15 degrees F to 400 degrees F. Fluoroelastomer construction delivers low gas permeability and a low compression set, making it appropriate for high-temperature hydraulic, pneumatic, and chemical sealing applications. Licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance mechanics are the typical installers.

This O-ring is suited for use in residential and commercial systems where petroleum-based fluids, fuels, or high-temperature media are present. Typical applications include hydraulic cylinder rod seals, valve body seals, pump housing seals, and compressed-gas fittings. The Dash 273 designation corresponds to a standardized AS568 groove dimension, making cross-referencing to existing hardware straightforward. The fluoroelastomer compound also provides a wide spectrum of chemical compatibility, including resistance to petroleum products, oils, and many solvents encountered in HVAC and plumbing service environments.

Key Features

• Fluoroelastomer (Viton-type) material with good resistance to petroleum products and chemical exposure
• Service temperature range of -15 degrees F to 400 degrees F
• Round cross-section with low compression set for consistent long-term sealing
• Low gas permeability makes this O-ring suitable for vacuum service and compressed-gas applications
• 70 durometer hardness rating provides a firm seal under elevated pressure and temperature cycling
• Dash 273 sizing conforms to AS568 standard groove dimensions for straightforward replacement

Compatibility

Designed as an OEM-style replacement for any application requiring a Dash 273 O-ring with fluoroelastomer construction, including hydraulic, pneumatic, plumbing, and HVAC sealing assemblies compatible with petroleum-based media.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable codes such as ASME, IPC, or IFGC depending on the system type. Always depressurize and isolate the system before removing the old O-ring, and verify that all mating surfaces are clean and free of debris before seating the new ring. Lubricate the O-ring with a compatible fluid or grease rated for fluoroelastomer compounds before installation to reduce the risk of tearing during assembly. Never stretch or roll the O-ring over sharp threads.
