Value Collection ZMSCE70105 Epdm O-ring Dash 105 Pack 100

Product Description

The VALUE COLLECTION ZMSCE70105 is a Dash 105 EPDM O-ring with a round cross section, sized at 0.156 inches inside diameter, 0.344 inches outside diameter, and 0.094 inches thick. Rated at 70 durometer hardness, it is engineered for sealing in systems that handle hot water, steam, and phosphate ester hydraulic fluids. The EPDM compound provides a wide service temperature range of -65 degrees F to 300 degrees F, making it suitable for demanding thermal cycling environments. HVAC technicians, plumbers, and hydraulic system technicians install these rings as static or dynamic seals in fittings, valves, and fluid connectors.

This O-ring is appropriate for residential and commercial HVAC hydronic systems, steam distribution lines, and hydraulic circuits using phosphate ester-based fluids such as Skydrol in commercial aircraft applications. The Dash 105 sizing is a standard dimension widely used across fluid handling assemblies. Sold in a package of 100, this SKU suits service technicians who need a bulk supply of this ring size for recurring maintenance, retrofit work, or field repair kits.

Key Features

• EPDM material rated for hot water, steam, and phosphate ester hydraulic fluid compatibility
• Service temperature range from -65 degrees F to 300 degrees F
• 70 durometer hardness rating for firm sealing under pressure
• Round cross section geometry conforms to standard Dash 105 dimensional specifications
• Sold in a 100-piece package to support bulk service and maintenance needs

Compatibility

Compatible with systems handling hot water, steam, and phosphate ester type hydraulic fluids. Designed as a standard Dash 105 replacement O-ring for use in fluid fittings, valves, and connectors across HVAC, plumbing, and hydraulic applications where EPDM compound is specified.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Shut down and depressurize the system and allow all components to reach a safe handling temperature before removing any existing seals. Inspect the seating groove for scoring or debris before installing the new ring, and apply a compatible lubricant rated for EPDM and the system fluid to ease installation and prevent tearing. Verify the groove dimensions match the Dash 105 specification before installation.
