Value Collection ZMSCV70271 Viton O-ring Dash 271

Product Description

The VALUE COLLECTION ZMSCV70271 is a Dash 271 Viton O-ring designed for sealing applications that demand resistance to high temperatures, petroleum-based fluids, and a wide range of chemicals. Manufactured from fluoroelastomer with a hardness of 70 Shore A, this O-ring measures 9.25 inches inside diameter, 9.5 inches outside diameter, and 0.125 inches thick. Its round cross-section profile seats consistently in standard grooves, providing a reliable static or low-dynamic seal. Licensed HVAC technicians, plumbers, and industrial mechanics typically install this part in pump housings, valve bonnets, flanged connections, and related fluid-handling equipment.

This O-ring is suited for residential and commercial applications where service fluids include petroleum products, oils, fuels, and hydraulic media. The fluoroelastomer compound handles continuous exposure to elevated temperatures and resists low gas permeation, making it appropriate for vacuum service as well as pressurized systems. The Dash 271 designation identifies the dimensional standard, simplifying cross-reference when replacing worn or failed seals during routine maintenance or repair. Each package contains two O-rings.

Key Features

• 70 Shore A hardness rating delivers a firm, stable seal with low compression set over extended service cycles
• Good resistance to petroleum products, oils, and a wide spectrum of chemicals
• Suitable for vacuum service with low gas permeability
• Round cross-section seats consistently in standard Dash 271 grooves
• Sold in a package of two, with a minimum order quantity of one package

Compatibility

Designed as a standard Dash 271 fluoroelastomer O-ring replacement for pump housings, valve bodies, flanged assemblies, and other fluid-handling components that specify a 9.25-inch ID, 9.5-inch OD, 0.125-inch thick round cross-section seal. Compatible with petroleum products and related media as noted in the product specifications.

Installation Notes

Power down or depressurize the system and isolate all fluid flow before removing the old O-ring. Clean the groove thoroughly and inspect for damage or out-of-round wear before seating the new ring. Apply a thin film of a compatible lubricant to ease installation and avoid twisting or spiraling the O-ring during assembly. Verify groove dimensions match the Dash 271 standard prior to installation to ensure proper compression and seal integrity.
