Value Collection ZMSCV70154 Viton O-ring Dash 154

Product Description

The VALUE COLLECTION ZMSCV70154 is a Dash 154 Viton fluoroelastomer O-ring designed for static and dynamic sealing applications in systems handling petroleum products, fuels, and a wide range of chemical media. Measuring 3.75 inches inside diameter with a 3.938-inch outside diameter and a 3/32-inch (0.0937-inch) cross section, this round-profile ring carries a 70 Shore A durometer rating, placing it in the hard range for reduced compression set under sustained clamp loads. Each package contains 2 rings. Fluoroelastomer construction provides high-temperature resistance up to 400 degrees F and low gas permeability, making it well suited for vacuum service and fuel-system sealing.

This O-ring is used across residential and commercial maintenance applications wherever a Dash 154 seal is required — including HVAC refrigerant fittings, plumbing connections, hydraulic assemblies, and pool or pump equipment using petroleum-compatible fluids. The fluoroelastomer material handles exposure to oils, fuels, and many aggressive chemicals without swelling or hardening. Technicians working on fuel valves, pump flanges, or compressor ports will find this a direct dimensional replacement for any Dash 154 cross-reference. The -15 degrees F minimum working temperature limits use in extreme cold environments.

Key Features

• Fluoroelastomer (Viton-type) material: good resistance to petroleum products and a wide spectrum of chemicals
• Temperature range: -15 degrees F to 400 degrees F for high-heat sealing environments
• 70 Shore A hardness provides low compression set under sustained load
• Low gas permeability — suitable for vacuum service applications
• Round cross section for consistent seating in standard O-ring grooves
• Package includes 2 O-rings per order unit

Compatibility

Designed as a standard Dash 154 O-ring replacement compatible with grooves and fittings engineered to the Dash 154 dimension series; suitable for use with petroleum products and compatible fluid systems as specified by the equipment manufacturer.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or mechanical service professionals. De-energize the system, relieve all pressure, and drain or isolate the fluid circuit before removing the old seal. Inspect the groove for nicks or debris before seating the new ring. Do not roll or twist the O-ring during installation, and use only lubricants rated compatible with fluoroelastomer and the system fluid.
