Value Collection ZMSCV70383 Viton O-ring Dash 383

Product Description

The VALUE COLLECTION ZMSCV70383 is a Dash 383 Viton (fluoroelastomer) O-ring with a 14-inch inside diameter, 14.375-inch outside diameter, and a 3/16-inch (0.1875-inch) round cross section. Rated at 70 Shore A hardness, this O-ring is built for demanding sealing applications where petroleum product exposure, elevated temperatures up to 400 degrees F, and vacuum service are concerns. The fluoroelastomer compound delivers low compression set and low gas permeability, making it a reliable static or dynamic seal for industrial, hydraulic, and fluid-handling systems. It is sold and packaged individually.

This O-ring is suited for use in large-bore sealing applications across industrial, commercial, and heavy-equipment environments. Its wide chemical compatibility profile makes it appropriate for systems handling petroleum-based fluids, hydraulic oils, and similar media. Typical install scenarios include pump housings, manifold covers, valve bonnets, and large-diameter pipe flanges where a robust elastomeric seal is required. Plumbers, pipefitters, hydraulic technicians, and industrial maintenance professionals commonly specify this size and compound for planned maintenance and repair work.

Key Features

• Fluoroelastomer (Viton) compound with good resistance to petroleum products and hydraulic fluids
• Operating temperature range of -15 degrees F to 400 degrees F
• 70 Shore A hardness rating for a hard, low-compression-set seal
• Round cross section with low gas permeability — suitable for vacuum service
• Wide spectrum of chemical compatibility for use across multiple fluid types
• Dash 383 standard sizing for straightforward cross-reference and replacement sourcing

Compatibility

Designed as a standard Dash 383 O-ring replacement for large-bore sealing applications requiring fluoroelastomer material compatibility with petroleum products and high-temperature service. Consult system OEM documentation to confirm groove dimensions and compound requirements before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with the host system — industrial pipefitters, hydraulic technicians, or licensed plumbers as appropriate. De-energize, depressurize, and fully drain the system before removing the existing seal. Inspect the O-ring groove for scoring, corrosion, or debris and clean thoroughly before seating the new O-ring. Avoid using sharp tools that could nick or cut the elastomer during installation.
