Value Collection ZMSCV1.6X3.1 Viton O-ring 3.1in Id

Product Description

The VALUE COLLECTION ZMSCV1.6X3.1 is a Viton (fluoroelastomer) O-ring with a round cross section, designed for sealing applications that demand resistance to high temperatures, petroleum products, and a wide range of chemicals. It measures 3.1 inches inside diameter, 6.3 inches outside diameter, and 1.6 inches thick. The material carries a Shore A hardness rating of 75, placing it in the hard durometer range. This O-ring is suited for static and dynamic sealing duties across HVAC, plumbing, industrial, and fluid-handling systems where standard nitrile or EPDM compounds fall short. Licensed tradespeople and industrial maintenance technicians are the primary installers.

This O-ring fits sealing grooves requiring a 3.1-inch ID and 1.6-inch cross-section thickness in round-groove configurations. It is rated for service from -15 degrees F to 400 degrees F, making it appropriate for high-temperature fluid systems, petroleum-based media lines, vacuum service applications, and environments requiring low gas permeability. Its fluoroelastomer compound also provides low compression set, which helps maintain a reliable seal over extended service intervals. This part is sold in packages of 25 units, with a minimum order quantity of 1.

Key Features

• Fluoroelastomer (Viton) compound offers broad chemical compatibility and petroleum-product resistance
• Rated from -15 degrees F to 400 degrees F for high-temperature service
• Shore A hardness of 75 (hard rating) reduces compression set over time
• Round cross-section profile fits standard O-ring grooves
• Suitable for vacuum service and low gas permeability applications
• Sold in a package quantity of 25

Compatibility

Designed as an OEM-style replacement or service O-ring for sealing applications requiring a 3.1-inch inside diameter, 6.3-inch outside diameter, 1.6-inch thick round cross-section fluoroelastomer seal compatible with petroleum products and high-temperature media.

Installation Notes

O-ring installation is performed by licensed HVAC technicians, plumbers, or industrial mechanics depending on the system. Always depressurize and lock out the system before removing the old seal. Inspect the groove for scoring or debris before seating the new O-ring, and apply a compatible lubricant to ease installation without distorting the cross section. Do not stretch the O-ring beyond what is necessary to seat it in the groove.
