Value Collection ZMSCV70318 Viton O-ring Dash 318 10pk

Product Description

The VALUE COLLECTION ZMSCV70318 is a Dash 318 Viton (fluoroelastomer) O-ring sold in a pack of 10. It features a round cross section with a 1.0000 inch inside diameter, a 1.3750 inch outside diameter, and a 0.1875 inch thickness. Rated at 70 Shore A hardness, this O-ring is engineered for sealing applications that demand resistance to high temperatures, petroleum-based fluids, and a wide range of chemicals. It is suited for use in hydraulic, pneumatic, fuel system, and vacuum service applications where standard nitrile O-rings fall short. Licensed plumbers, HVAC technicians, and industrial maintenance techs specify fluoroelastomer O-rings when working temperatures or fluid compatibility push beyond the limits of general-purpose elastomers.

This O-ring is appropriate for residential and commercial fluid-handling systems, fuel lines, refrigeration service connections, and vacuum service assemblies. Its low compression set and low gas permeability make it a reliable choice for static and dynamic sealing in environments exposed to petroleum products and elevated heat. Applications span HVAC equipment service ports, plumbing fittings, and industrial fluid-power assemblies requiring a Dash 318 dimensioned seal.

Key Features

• Fluoroelastomer (Viton) construction provides high chemical and petroleum resistance
• Operates across a wide temperature range from -15 degrees F to 400 degrees F
• 70 Shore A hardness rating suits both static and dynamic sealing applications
• Round cross section with low compression set for consistent sealing force over time
• Low gas permeability makes this suitable for vacuum service
• Sold in a pack of 10 with a minimum order quantity of 1 pack

Compatibility

Designed as an OEM-style replacement or service O-ring for any application requiring a Dash 318 fluoroelastomer seal. Compatible with petroleum products and a wide spectrum of chemicals as noted in manufacturer specifications.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial mechanic. Always depressurize and drain the system, and shut off all fluid or gas supply before replacing O-rings. Lubricate the O-ring with a compatible fluid or grease prior to seating to reduce installation stress and prevent tearing. Avoid overstretching the O-ring during installation; use a proper O-ring installation tool when working in confined grooves.
