Value Collection ZMSCS70041 Silicone O-ring Dash 041

Product Description

The VALUE COLLECTION ZMSCS70041 is a round cross-section silicone O-ring designed for static and dynamic sealing applications across a wide range of industrial and mechanical systems. With a 3-inch inside diameter, 3.125-inch outside diameter, and 0.0625-inch thickness, this Dash 041 O-ring provides a reliable seal where temperature extremes and environmental exposure are primary concerns. Silicone construction gives the ring strong dry heat resistance, good ozone and weather resistance, and a usable temperature range from -80 degrees F to 450 degrees F. Sold in packages of 10, this O-ring is installed by plumbers, HVAC technicians, maintenance mechanics, and pipefitters.

This O-ring is suited for applications requiring sealing integrity across wide thermal cycling, including HVAC equipment connections, fluid handling assemblies, and industrial machinery interfaces. The silicone compound offers limited oil resistance but performs well in contact with certain chemicals and solvents. It is appropriate for residential and commercial mechanical systems where dry heat exposure and ozone resistance are more critical than petroleum-fluid compatibility. White coloring aids visual identification during assembly and inspection.

Key Features

• Silicone material rated for -80 degrees F to 450 degrees F continuous service
• Dash 041 designation: 3-inch ID, 3.125-inch OD, 0.0625-inch cross-section thickness
• Hardness rating of 70 Shore A for firm, consistent sealing compression
• Good resistance to weather, ozone, and dry heat environments
• Compatible with certain oils, chemicals, and solvents; limited petroleum-oil resistance
• Round cross-section profile for standard O-ring groove fitment

Compatibility

Designed as a standard Dash 041 silicone O-ring for use in any groove or fitting that accepts a 3-inch ID round cross-section O-ring, particularly in applications requiring wide temperature tolerance and ozone resistance.

Installation Notes

O-rings should be installed by a qualified technician familiar with sealing system requirements. Always depressurize and de-energize the system before replacing any O-ring. Inspect the mating groove and sealing surfaces for damage or debris before installation. Avoid stretching the O-ring beyond its rated diameter during installation to prevent deformation and premature seal failure.
