Value Collection ZMSCS70113 Silicone O-ring Dash 113 100-pack

Product Description

The VALUE COLLECTION ZMSCS70113 is a Dash 113 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and fluid-handling systems. It measures 0.563 inches inside diameter and 0.750 inches outside diameter, with a round cross-section thickness of 0.094 inches. The compound is silicone at a Shore A hardness of 70, rated for continuous service from -80 degrees F to 450 degrees F. That wide thermal range makes it appropriate for dry-heat environments, outdoor exposure, and applications where ozone or weather resistance is required. Licensed technicians and pipefitters stock this size for quick field replacement of worn or damaged seals in valves, fittings, and mechanical connections.

The ZMSCS70113 suits residential and light commercial installations where the service fluid is compatible with silicone elastomer. Typical applications include HVAC equipment seals, plumbing shutoff valves, pool and spa pump fittings, and chemical-handling connections where oils, solvents, and general chemicals are present at low-to-moderate concentrations. The white silicone construction is visible during inspection, which is useful for confirming correct seal placement in grooved or recessed glands. Sold in a package quantity of 100 units, making it practical for service vans and shop replenishment.

Key Features

• Dash 113 standard sizing: 0.563 inches ID, 0.750 inches OD, 0.094 inches thick
• Silicone compound rated from -80 degrees F to 450 degrees F for wide-range thermal service
• Shore A 70 hardness providing a firm, resilient seal under compression
• Round cross-section for consistent gland fit and predictable compression set
• Good resistance to ozone, weathering, and dry heat degradation
• Compatible with oils, chemicals, and solvents at applicable concentration limits

Compatibility

Compatible with applications requiring resistance to oils, chemicals, and solvents. Recommended for use where a wide temperature range and good dry heat resistance are needed. Silicone elastomer has limited oil resistance; verify fluid compatibility before installation in high-oil-concentration environments.

Installation Notes

O-ring installation should be performed by a qualified technician familiar with the applicable system type. Shut off and depressurize the system before removing any seals or fittings. Inspect the gland groove for nicks, burrs, or debris that could damage the new seal before seating. Do not roll or twist the O-ring during installation, and avoid petroleum-based lubricants with silicone compounds unless confirmed compatible with the service fluid.
