Value Collection ZMSCV70366 Viton O-ring Dash 366

Product Description

The VALUE COLLECTION ZMSCV70366 is a Viton (fluoroelastomer) O-ring designed for static and dynamic sealing applications where chemical resistance and high-temperature performance are required. Measuring 7.25 inches inside diameter, 7.625 inches outside diameter, and 0.1875 inches thick, this is a Dash 366 size with a round cross section. The compound carries a Shore A hardness rating of 70, placing it in the hard durometer range. It is rated for continuous service from -15 degrees F up to 400 degrees F, making it suitable for demanding industrial and mechanical sealing applications. Each package contains 2 O-rings.

This O-ring is suited for use in HVAC equipment, plumbing assemblies, hydraulic systems, and mechanical seals where exposure to petroleum-based fluids, fuels, or elevated operating temperatures is expected. The fluoroelastomer compound provides low gas permeability, making it appropriate for vacuum service as well as pressurized fluid containment. Licensed tradespeople, mechanical contractors, and maintenance technicians typically install this size in large-bore flanged connections, pump housings, and valve assemblies.

Key Features

• Fluoroelastomer (Viton) compound delivers wide-spectrum chemical compatibility with petroleum products, fuels, and many solvents
• Rated from -15 degrees F to 400 degrees F for reliable performance in high-temperature environments
• 70 Shore A hardness provides a hard durometer rating with low compression set over service life
• Round cross section and Dash 366 sizing for straightforward groove fitment
• Low gas permeability makes it suitable for vacuum service applications
• Sold in a package of 2 O-rings per order

Compatibility

Designed as a Dash 366 O-ring replacement compatible with grooves and glands sized for a 7.25-inch inside diameter, 7.625-inch outside diameter, and 0.1875-inch cross section. Compatible with petroleum products and applications requiring fluoroelastomer chemical resistance.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson following equipment manufacturer service procedures. Shut down and depressurize the system completely before removing the old O-ring. Inspect the gland and mating surfaces for scoring or corrosion before seating the new O-ring. Use only lubricants compatible with fluoroelastomer compounds to avoid premature degradation of the sealing element.
