Value Collection ZMSCE70212 Epdm O-ring Dash 212 Pack of 100

Product Description

The VALUE COLLECTION ZMSCE70212 is a Dash 212 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications in fluid handling systems. It measures 0.875 inches inside diameter, 1.125 inches outside diameter, and 0.125 inches thick. Molded from Ethylene Propylene Diene Monomer (EPDM) at 70 Shore A hardness, this O-ring resists degradation when exposed to hot water, steam, and phosphate ester hydraulic fluids. It is installed by licensed plumbers, HVAC technicians, and hydraulic system technicians where reliable elastomeric sealing is required across a wide service temperature range.

This O-ring is suited for residential and commercial plumbing systems, steam service, and hydraulic circuits that use phosphate ester-based fluids such as Skydrol-type aviation hydraulic fluids. The Dash 212 sizing makes it a standard replacement in valve assemblies, pump housings, pipe fittings, and hydraulic manifolds where this dimensional class is specified. Sold in a package quantity of 100, making it appropriate for stocking, batch maintenance, or service van inventory. Not recommended for use with petroleum-based oils or fuels, which can degrade EPDM compound.

Key Features

• EPDM compound delivers excellent resistance to hot water and steam service up to 300 degrees F
• Rated for phosphate ester hydraulic fluids, including Skydrol-type fluids used in commercial aircraft hydraulic systems
• 70 Shore A hardness provides firm sealing under compression without excessive extrusion at working pressures
• Round cross section conforms to standard O-ring groove dimensions for Dash 212 series
• Wide service temperature range: -65 degrees F minimum to 300 degrees F maximum
• Sold in a pack of 100 for maintenance stocking and high-volume service applications

Compatibility

Compatible sealing media include hot water, steam, and phosphate ester type hydraulic fluids. This O-ring is not FDA approved and is not intended for food-contact or potable water applications where FDA compliance is required.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or hydraulic system technicians. Depressurize and drain the system fully before removing the existing O-ring and inspect the groove for wear, scoring, or debris before seating the replacement. Lubricate the O-ring with a compatible fluid or assembly lubricant rated for EPDM — do not use petroleum-based greases, as they will degrade the compound. Follow applicable codes including IPC and IFGC for plumbing and gas system sealing applications.
