Value Collection ZMSCE70363 O-ring Dash 363 Epdm 70

Product Description

The VALUE COLLECTION ZMSCE70363 is a Dash 363 EPDM O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and steam systems. It measures 6.5 inches inside diameter, 6.875 inches outside diameter, and 0.1875 inches thick. Molded from ethylene propylene diene monomer (EPDM) compound at a 70 Shore A hardness, this O-ring delivers reliable sealing performance across a wide service temperature range of -65 degrees F to 300 degrees F. Licensed plumbers, millwrights, and industrial maintenance technicians routinely specify this profile for high-temperature fluid sealing tasks.

This O-ring is suited for use in hot water systems, steam service, and phosphate ester type hydraulic fluid circuits. It also demonstrates excellent resistance to Skydrol fluids used in commercial aircraft hydraulic systems, making it a practical choice for aerospace ground support and MRO applications in addition to plumbing and industrial fluid handling. Each package contains 7 pieces, and the minimum order quantity is 1.

Key Features

• Compatible with phosphate ester hydraulic fluids and Skydrol aerospace hydraulic fluids
• 70 Shore A hardness rating for a firm, reliable seal under pressure
• Wide operating temperature range: -65 degrees F to 300 degrees F
• Round cross-section profile conforms to standard Dash 363 dimensions
• Sold in a 7-piece package with a minimum order quantity of 1

Compatibility

Designed for sealing applications involving hot water, steam, and phosphate ester type hydraulic fluids. Also recommended for systems utilizing Skydrol fluids in commercial aircraft hydraulic circuits. Verify groove dimensions against Dash 363 standards before installation.

Installation Notes

Installation should be performed by a qualified plumber, hydraulic technician, or licensed mechanic following applicable system codes. Depressurize and drain the system completely before removing the old O-ring or installing a new one. Lubricate the O-ring with a fluid compatible with EPDM prior to seating to reduce the risk of tearing during assembly. Avoid using petroleum-based lubricants, as they are not compatible with EPDM elastomers.
