Value Collection ZMSCE70330 O-ring Dash 330 Epdm 10-pack

Product Description

The VALUE COLLECTION ZMSCE70330 is a Dash 330 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and thermal systems. It measures 2.125 inches inside diameter, 2.5 inches outside diameter, and 0.1875 inches thick. The compound is Ethylene Propylene Diene Monomer (EPDM) with a 70-durometer hardness rating, making it suitable for high-temperature and chemically aggressive service environments. Licensed plumbers, HVAC technicians, and industrial maintenance techs install these rings wherever a reliable face or radial seal is required. Each package contains 10 rings.

This O-ring is rated for service from -65 degrees F to 300 degrees F, covering a broad range of residential and commercial applications. Compatible media include hot water, steam, and phosphate ester type hydraulic fluids. It also provides excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems. Typical installations include pipe flanges, pump housings, valve stems, and hydraulic manifolds where EPDM compatibility with the process fluid has been confirmed.

Key Features

• EPDM material offers strong resistance to hot water, steam, and phosphate ester hydraulic fluids
• Excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems
• 70-durometer hardness provides a firm, reliable seal under compression
• Wide temperature range: -65 degrees F to 300 degrees F
• Round cross section for consistent sealing geometry and predictable compression set
• Sold in a pack of 10 for efficient stocking and service-call readiness

Compatibility

Compatible with hot water, steam, and phosphate ester type hydraulic fluid systems. Also suitable for Skydrol fluid service in commercial aircraft hydraulic applications. Confirm EPDM chemical compatibility with the specific process fluid before installation.

Installation Notes

O-ring installation should be performed by a licensed plumber, HVAC technician, or qualified maintenance professional. Shut off and depressurize the system completely before replacing any sealing components. Inspect the mating groove for burrs, scoring, or contamination prior to seating the ring. Do not stretch the O-ring beyond minimum necessary to fit the groove, and avoid twisting during installation to prevent uneven compression and premature failure.
