Value Collection ZMSCV70247 Viton O-ring Dash 247 Pack of 5

Product Description

The VALUE COLLECTION ZMSCV70247 is a Dash 247 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where elevated temperatures and petroleum-based fluid exposure are primary concerns. With a 4.625-inch inside diameter, 4.875-inch outside diameter, and a 0.125-inch round cross section, this O-ring fits large-bore sealing grooves common in industrial and mechanical assemblies. The 70 durometer hardness rating balances flexibility and compression resistance. Viton compound delivers low compression set, low gas permeability, and broad chemical compatibility. This package contains 5 O-rings. Licensed tradespeople and industrial maintenance technicians are the typical installers.

This O-ring is suited for hydraulic systems, pneumatic assemblies, pump housings, valve bodies, and piping flanges that handle petroleum products, fuels, oils, and high-temperature process fluids. The fluoroelastomer compound performs reliably from -15 degrees F to 400 degrees F, making it appropriate for demanding service environments where standard Buna-N rings fail prematurely. It is also rated for vacuum service due to its low gas permeability, which extends its usefulness to vacuum pump sealing and low-pressure gas containment applications.

Key Features

• Fluoroelastomer (Viton) compound rated from -15 degrees F to 400 degrees F continuous service
• 70 durometer hardness for firm sealing under pressure without excessive deformation
• Low gas permeability suitable for vacuum service and gas containment
• Good resistance to petroleum products, fuels, and a wide spectrum of chemicals
• Low compression set maintains seal integrity over extended service intervals
• Round cross section in Dash 247 standard sizing for drop-in replacement compatibility

Compatibility

Compatible with systems and assemblies handling petroleum products, fuels, and high-temperature fluids where Dash 247 fluoroelastomer O-rings are specified. Not FDA approved; not intended for food-contact or potable-water service.

Installation Notes

Installation should be performed by a qualified mechanic or technician familiar with O-ring groove specifications and sealing system requirements. Relieve all system pressure and drain fluid before disassembling any housing or valve body. Inspect the groove for nicks, burrs, or corrosion before seating the new O-ring; use only a compatible, petroleum-based or fluoroelastomer-safe lubricant to ease installation and prevent cutting the ring on sharp edges. Do not roll or twist the O-ring during installation, as this compromises the sealing surface.
