Value Collection ZMSCV2.5X19 Viton O-ring 19x24x2.5 in

Product Description

The VALUE COLLECTION ZMSCV2.5X19 is a heavy-duty Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications that demand high temperature tolerance and broad chemical resistance. With a 19-inch inside diameter, 24-inch outside diameter, and a 2.5-inch cross-section thickness, this large-format O-ring suits industrial and mechanical sealing systems where standard-size rings fall short. The round cross-section profile provides consistent compression and reliable sealing surface contact. A hardness rating of 75 Shore A places this ring in the hard range, supporting low compression set across demanding service cycles. Rated for operating temperatures from -15 degrees F to 400 degrees F, it holds integrity where many elastomers fail.

This O-ring is well suited for industrial fluid systems, hydraulic assemblies, pump housings, and vacuum service applications that involve petroleum-based media or high-temperature environments. Its wide spectrum of chemical compatibility and low gas permeability make it a practical choice for refinery, chemical processing, and heavy mechanical maintenance scenarios. Licensed tradespeople and industrial maintenance technicians working with large-bore sealing applications will find this ring appropriate for both planned maintenance and emergency repair situations.

Key Features

• Fluoroelastomer (Viton) compound provides strong resistance to petroleum products and a wide range of industrial chemicals
• Rated from -15 degrees F to 400 degrees F for reliable performance in high-temperature service
• 75 Shore A hardness delivers low compression set and long service life under sustained load
• Round cross-section geometry ensures uniform sealing contact and repeatable compression
• Suitable for vacuum service with low gas permeability characteristics
• Large-format dimensions (19-inch ID, 24-inch OD) cover industrial and heavy mechanical applications

Compatibility

Designed for use in systems handling petroleum products and compatible fluids. Suitable for industrial hydraulic, pneumatic, pump, and vacuum sealing applications requiring a large-bore fluoroelastomer O-ring. Verify groove dimensions and media compatibility before installation.

Installation Notes

Installation should be performed by a qualified industrial or mechanical technician familiar with large-format sealing components. De-energize and depressurize the system fully and confirm zero pressure before removing the existing seal or installing the replacement ring. Inspect the groove and mating surfaces for scratches, corrosion, or debris that could compromise the seal. Avoid twisting or overstretching the O-ring during installation; use a compatible lubricant approved for fluoroelastomer compounds and the system media.
