Value Collection ZMSCE70018 Epdm O-ring Dash 018 Pack of 50

Product Description

The VALUE COLLECTION ZMSCE70018 is an EPDM O-ring with a round cross section, sized at 0.750 inches inside diameter, 0.875 inches outside diameter, and 0.0625 inches thick. It carries a Dash 018 designation and a Shore A hardness rating of 70, placing it in the hard hardness category. EPDM compound delivers strong resistance to hot water, steam, and phosphate ester hydraulic fluids, as well as Skydrol fluids used in commercial aircraft hydraulic systems. Licensed plumbers, HVAC technicians, and fluid-systems technicians install these O-rings as seals in piping connections, valve stems, and hydraulic fittings where standard nitrile compounds would degrade.

This O-ring is suited for residential and commercial plumbing, hydronic heating systems, and hydraulic fluid circuits where exposure to hot water or steam is common. The EPDM material handles a working temperature range of -65 degrees F to 300 degrees F, making it viable in high-temperature service environments. It is also specified in aviation and industrial hydraulic applications where phosphate ester fluids such as Skydrol are present. Each package contains 50 O-rings, with a minimum order quantity of 1 package.

Key Features

• EPDM compound rated for hot water, steam, and phosphate ester hydraulic fluids including Skydrol
• Working temperature range of -65 degrees F to 300 degrees F
• Shore A hardness of 70 (hard rating) for firm, reliable sealing under pressure
• Round cross section, Dash 018 designation for standardized fitment
• Black color for easy visual identification in fluid system maintenance

Compatibility

Compatible with systems handling hot water, steam, and phosphate ester type hydraulic fluids. Suitable for use in commercial aircraft hydraulic systems where Skydrol fluids are present. Designed as a Dash 018 standard O-ring for any application requiring a 0.750 inch ID round-cross-section seal in an EPDM-compatible fluid environment.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, or qualified hydraulic system technicians. Before replacing any O-ring seal, depressurize and drain the affected system completely and allow all components to cool to a safe handling temperature. Inspect the seating groove for damage or debris before installation. Avoid using petroleum-based lubricants with EPDM O-rings; use only water-based or EPDM-compatible assembly lubricants to prevent compound degradation.
