Value Collection ZMSCS70115 Silicone O-ring Dash 115 100-pack

Product Description

The VALUE COLLECTION ZMSCS70115 is a Dash 115 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, and industrial fluid systems. It measures 0.688 inches inside diameter by 0.875 inches outside diameter with a 3/32-inch (0.0937-inch) round cross-section thickness. The compound carries a 70-durometer hardness rating, placing it in the hard range, and is rated for continuous service from -80 degrees F to 450 degrees F. This wide thermal range makes it suitable for high-heat and cold-environment sealing where standard Buna-N rings would degrade. Licensed technicians and journeymen plumbers working on equipment with elevated temperature exposure rely on silicone compounds for long-term seal integrity.

This O-ring is suited for residential and light commercial applications where dry heat resistance, weather stability, and ozone resistance are required. Typical install scenarios include sealing around HVAC components, refrigerant-adjacent assemblies where silicone is appropriate, water lines, and general mechanical equipment. The silicone compound also offers limited compatibility with oils, chemicals, and solvents, making it a broad-use seal for mixed-fluid environments. This item is sold in a package quantity of 100, with a minimum order quantity of 1 package, making it practical for bench-stock or service-truck stocking.

Key Features

• Silicone compound rated from -80 degrees F to 450 degrees F for wide-range thermal service
• Round cross-section at 0.0937 inches thick for consistent seating in standard Dash 115 grooves
• 70-durometer hardness for firm sealing under compression
• Good weather and ozone resistance extends service life in exposed or outdoor installations
• Compatible with oils, chemicals, and solvents in limited-contact applications
• Sold as a 100-piece pack for efficient bench-stock replenishment

Compatibility

Designed to fit standard Dash 115 O-ring grooves per AS568 sizing conventions. Suitable as a replacement or service seal in any application specifying a 0.688-inch ID by 0.875-inch OD silicone O-ring with a 3/32-inch cross section.

Installation Notes

Silicone O-rings should be installed by a qualified technician following system manufacturer specifications and applicable codes such as IPC or IFGC for plumbing and gas applications. Power down or depressurize the system fully before removing or replacing any seal. Avoid using petroleum-based lubricants with silicone compounds; use a silicone-compatible assembly lubricant only. Inspect the seating groove for burrs or debris before installation to prevent premature seal failure.
