Value Collection ZMSCV2X4 Viton O-ring 4x8x2 Inch 25-pack

Product Description

The VALUE COLLECTION ZMSCV2X4 is a round cross-section O-ring manufactured from fluoroelastomer (Viton), designed for static and dynamic sealing applications where exposure to petroleum products, high temperatures, or aggressive chemicals is expected. The ring measures 4 inches inside diameter, 8 inches outside diameter, and 2 inches thick. With a durometer hardness rating of 75 Shore A, it maintains a low compression set and resists deformation under sustained load. The operating temperature range spans -15 degrees F to 400 degrees F, making it suitable for demanding service environments. Licensed mechanical contractors and industrial maintenance technicians are the primary installers.

This O-ring is suited for hydraulic systems, fuel handling equipment, chemical processing lines, and vacuum service applications where standard Buna-N or neoprene compounds fall short. The fluoroelastomer compound provides wide-spectrum chemical compatibility and low gas permeability, which is critical in vacuum and high-pressure fluid containment. This SKU is sold in a package quantity of 25 rings, appropriate for stocking or multi-unit service work. Typical applications include pump seals, valve packing, and flange face sealing in both industrial and commercial mechanical systems.

Key Features

• Fluoroelastomer (Viton) compound with good resistance to petroleum products and fuels
• Operating range of -15 degrees F to 400 degrees F for high-temperature service
• 75 Shore A hardness with low compression set for reliable long-term sealing
• Low gas permeability makes it suitable for vacuum service applications
• Wide spectrum of chemical compatibility for use in aggressive fluid environments
• Round cross-section profile; sold in a package of 25 units

Compatibility

Designed as a replacement or service-stock O-ring for industrial, hydraulic, and mechanical sealing applications requiring fluoroelastomer material compatibility with petroleum products and high-temperature service conditions.

Installation Notes

Installation is typically performed by licensed millwrights, pipefitters, or mechanical technicians. Always depressurize and lock out the system before removing existing seals. Ensure the gland groove dimensions match the O-ring cross-section and durometer to prevent extrusion or inadequate sealing. Do not use petroleum-based lubricants during installation; use a compatible assembly lubricant approved for fluoroelastomer compounds.
