Value Collection ZMSCV70046 Viton O-ring Dash 046 10pk

Product Description

The VALUE COLLECTION ZMSCV70046 is a Dash 046 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in HVAC, plumbing, and industrial fluid systems. It measures 4.25 inches inside diameter, 4.375 inches outside diameter, and 0.0625 inches thick. The fluoroelastomer compound delivers a Shore A hardness of 70 and handles operating temperatures from -15 degrees F to 400 degrees F. Licensed HVAC technicians, plumbers, and industrial mechanics use this O-ring where petroleum-fluid compatibility and high-temperature resistance are required.

This O-ring is suited for sealing flanges, valve bodies, pump housings, and refrigerant or hydraulic line fittings where exposure to petroleum products, oils, or elevated temperatures is expected. The Dash 046 sizing is a standard designation, making it a straightforward dimensional replacement in existing assemblies. Its low gas permeability also makes it appropriate for vacuum service and low-leak-rate gas line applications. Sold in a package of 10 units.

Key Features

• Fluoroelastomer (Viton) material with good resistance to petroleum products and hydraulic fluids
• Wide operating temperature range: -15 degrees F to 400 degrees F
• Shore A hardness rating of 70 for a firm, reliable seal under compression
• Low compression set reduces seal relaxation over time in static applications
• Low gas permeability makes it suitable for vacuum service and gas-line sealing
• Round cross section in standard Dash 046 sizing for drop-in dimensional replacement

Compatibility

Compatible with petroleum products, oils, and a wide spectrum of chemicals per the fluoroelastomer compound rating. Designed as a standard Dash 046 dimensional O-ring replacement in any assembly requiring a 4.25-inch ID, 4.375-inch OD, 0.0625-inch thick round-section seal.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or industrial mechanics. Always depressurize and de-energize the system before removing the old O-ring and inspect the gland seat for nicks or corrosion prior to seating the new ring. A thin film of compatible lubricant may be applied to ease installation and reduce the risk of tearing. Avoid twisting or rolling the O-ring into the groove, as this can compromise the seal cross section.
