Value Collection ZMSCV70231 Viton O-ring Dash 231 10-pack

Product Description

The VALUE COLLECTION ZMSCV70231 is a Dash 231 Viton (fluoroelastomer) O-ring with a round cross section, designed for sealing applications that demand resistance to high temperatures and petroleum-based fluids. It measures 2.625 inches inside diameter, 2.875 inches outside diameter, and 0.125 inches thick. Rated for continuous service from -15 degrees F to 400 degrees F, this O-ring is well suited for systems where conventional nitrile or neoprene seals would degrade. Its 70-durometer hardness provides a firm, low-compression-set seal. Each order ships in a pack of 10.

This O-ring is used across HVAC, refrigeration, plumbing, and industrial fluid-handling applications wherever a Dash 231 seal is specified. Typical install scenarios include pump housings, valve bodies, flanged connections, and hydraulic fittings that see petroleum-product exposure or elevated operating temperatures. The fluoroelastomer compound also makes it appropriate for vacuum service applications due to its low gas permeability. Licensed HVAC technicians, plumbers, and industrial maintenance mechanics are the primary installers.

Key Features

• Fluoroelastomer (Viton-type) compound resists petroleum products, fuels, and hydraulic fluids
• Wide service temperature range: -15 degrees F to 400 degrees F
• 70-durometer hardness rating delivers low compression set over repeated thermal cycles
• Low gas permeability makes it suitable for vacuum service
• Round cross section for standard O-ring groove seating
• Sold in a pack of 10, minimum order quantity of 1 pack

Compatibility

Designed as a Dash 231 standard O-ring replacement compatible with petroleum products and systems requiring broad chemical compatibility. Verify groove dimensions against 2.625 inches ID, 2.875 inches OD, and 0.125 inches cross-section thickness before installation.

Installation Notes

Power down or depressurize the system fully before removing the existing seal. Clean the groove of any debris or residue from the old O-ring before seating the new one. Lightly lubricate the O-ring with a compatible fluid-system lubricant to ease installation and prevent tearing during assembly. This part is not FDA approved and should not be used in food-contact or potable-water applications.
