Value Collection ZMSCVB75206 Viton O-ring Dash 206 25 Pack

Product Description

The VALUE COLLECTION ZMSCVB75206 is a Dash 206 Viton (fluoroelastomer) O-ring with a 0.5-inch inner diameter, 0.75-inch outer diameter, and a cross-section thickness of 0.125 inches. Viton material gives this seal a working temperature range of -15 degrees F to 400 degrees F, making it suited for high-heat and chemically demanding service environments. With a Shore A hardness of 75, it maintains shape under compression while providing a reliable static or dynamic seal. This package contains 25 O-rings. Licensed HVAC technicians, plumbers, and industrial mechanics commonly stock these seals for petroleum fluid systems, hydraulic circuits, and fuel-handling assemblies.

This O-ring is used in applications where petroleum-based fluids, fuels, oils, and a wide range of chemicals are present. The fluoroelastomer compound resists degradation from these media better than BUNA-N or EPDM alternatives. Typical install scenarios include fuel shutoff valves, hydraulic fittings, pump housings, and compressor service ports. The Dash 206 sizing is a widely referenced AS568 standard dimension, making this O-ring straightforward to cross-reference against existing seal kits and bill-of-materials specs.

Key Features

• Fluoroelastomer (Viton) compound resists petroleum products, fuels, oils, and a broad spectrum of chemicals
• Rated -15 degrees F to 400 degrees F for high-temperature sealing applications
• Shore A hardness of 75 for controlled compression set and long service life
• Low gas permeability makes it suitable for vacuum service and gas-handling systems
• Round cross-section profile conforms to AS568 Dash 206 standard dimensions
• Sold in a 25-piece package to support service stock and repair kit builds

Compatibility

Designed as a standard AS568 Dash 206 replacement O-ring for use in systems handling petroleum products, hydraulic fluids, fuels, and other media compatible with fluoroelastomer seals.

Installation Notes

Installation is performed by qualified mechanics, HVAC technicians, or plumbers depending on the system. Always depressurize and isolate the circuit before removing the old seal. Inspect the groove and mating surfaces for scoring or debris before seating the new O-ring. Avoid stretching the O-ring beyond what is necessary for installation, and apply a compatible lubricant to ease seating and reduce risk of damage during assembly.
