Value Collection ZMSCE70206 Epdm O-ring Dash 206 Pack 100

Product Description

The VALUE COLLECTION ZMSCE70206 is a Dash 206 EPDM O-ring designed for sealing applications in fluid and hydraulic systems. The ring measures 0.5 inches inside diameter, 0.75 inches outside diameter, and 0.125 inches thick, with a round cross section and a Shore A hardness rating of 70. EPDM (Ethylene Propylene Diene Monomer) provides strong resistance to heat, steam, and phosphate ester hydraulic fluids, making this O-ring a practical choice for demanding service environments. Each order contains 100 rings. Licensed plumbers, pipefitters, HVAC technicians, and hydraulic system mechanics are the typical installers of this component.

This O-ring is well suited for residential and commercial hot water systems, steam service lines, and hydraulic systems using phosphate ester fluids such as Skydrol used in commercial aircraft hydraulic circuits. It is also recommended for general-purpose sealing where EPDM compatibility is required. The 70 hardness rating provides firm compression without excessive deformation under standard clamping loads. Sold in packs of 100, making it practical for shop stock or service van inventory.

Key Features

• Shore A hardness of 70 for firm, reliable sealing compression

Compatibility

Designed for sealing applications involving hot water, steam, and phosphate ester hydraulic fluids. Compatible material types listed by the manufacturer include hot water, steam, and phosphate ester fluids. Not FDA approved; not intended for food-contact applications.

Installation Notes

Install by licensed plumbers, pipefitters, or qualified hydraulic system technicians following applicable local codes and system manufacturer requirements. Always depressurize and drain the system, and allow it to cool before replacing O-rings. Inspect the groove and mating surfaces for damage or debris before seating the new ring. Do not use petroleum-based lubricants with EPDM material; use a compatible assembly lubricant only.
