Value Collection ZMSCV70284 Viton O-ring Dash 284

Product Description

The VALUE COLLECTION ZMSCV70284 is a Dash 284 Viton (fluoroelastomer) O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and gas systems. It measures 18 inches inside diameter, 18.25 inches outside diameter, and 0.125 inches thick. The fluoroelastomer compound delivers low compression set, high-temperature resistance up to 400 degrees F, and a wide spectrum of chemical compatibility, including good resistance to petroleum products. It also performs well in vacuum service and exhibits low gas permeability. This O-ring is a general-purpose sealing component installed by plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals.

This O-ring is suited for use in large-diameter sealing applications where petroleum-based fluids, high temperatures, or chemical exposure is a factor. Its fluoroelastomer construction makes it appropriate for hydraulic systems, industrial fluid handling, HVAC refrigerant-side connections, and fuel-related service environments. It carries a hard (70 Shore A) durometer rating, making it well matched for applications requiring firm, long-lasting seals under pressure or elevated temperatures. It is sold individually and is not FDA approved, so it is not intended for food, beverage, or pharmaceutical contact applications.

Key Features

• Fluoroelastomer (Viton) material with 70 Shore A hardness for firm, durable sealing
• Rated for temperatures from -15 degrees F to 400 degrees F
• Good resistance to petroleum products and a wide range of chemicals
• Low compression set maintains seal integrity over time
• Suitable for vacuum service with low gas permeability
• Round cross section, Dash 284 standard sizing

Compatibility

Designed as an OEM-style replacement or service O-ring for large-diameter sealing applications in systems handling petroleum products, hydraulic fluid, or high-temperature gases where a Dash 284 fluoroelastomer O-ring is specified.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Always depressurize and isolate the system before removing or installing an O-ring. Inspect the mating groove for damage, debris, and correct dimensional tolerance before seating the new ring. A light application of compatible lubricant may aid installation, but verify lubricant compatibility with fluoroelastomer compounds and the system fluid before use.
