Value Collection ZMSCV70153 Viton O-ring Dash 153

Product Description

The VALUE COLLECTION ZMSCV70153 is a Dash 153 Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications in systems that handle petroleum products, high-temperature fluids, and chemical media. Measuring 3.5 inches inside diameter, 3.688 inches outside diameter, and 0.0937 inches thick, this round cross-section O-ring carries a hardness rating of 70 Shore A. Its fluoroelastomer compound delivers low compression set, high-temperature resistance, and low gas permeability, making it a reliable sealing choice in demanding service environments. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this style of O-ring during pump, valve, and fitting service work.

This O-ring suits a wide range of residential and commercial applications where petroleum-based fluids or elevated temperatures are present. Common install scenarios include pump body seals, valve bonnet seals, and flange face seals in plumbing, HVAC, and fluid-handling assemblies. The fluoroelastomer material provides broad chemical compatibility, making it appropriate for use in fuel systems, hydraulic circuits, and solvent-exposed environments. It is also rated for vacuum service, which extends its utility to refrigeration and process systems where low gas permeability is a requirement. Package quantity is 2 O-rings per pack.

Key Features

• Fluoroelastomer (Viton) compound with wide spectrum chemical compatibility
• Rated for operating temperatures from -15 degrees F to 400 degrees F
• Low compression set maintains seal integrity under sustained load
• Low gas permeability suitable for vacuum service applications
• Round cross-section profile for standard O-ring groove fitment
• Good resistance to petroleum products including fuels, oils, and hydraulic fluids

Compatibility

Designed as a standard Dash 153 O-ring replacement for any application requiring a 3.5-inch ID fluoroelastomer seal with a 3/32-inch cross section. Compatible with petroleum products and a wide spectrum of chemical media per manufacturer specifications.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always depressurize and drain the system before removing or replacing any O-ring seal. Clean the mating groove and sealing surfaces thoroughly before installing the new O-ring; inspect the groove for scoring or damage that could compromise the seal. Apply a compatible lubricant to the O-ring before installation to reduce the risk of tearing during assembly.
