Value Collection ZMSCS70038 Silicone O-ring Dash 038

Product Description

The VALUE COLLECTION ZMSCS70038 is a silicone O-ring with a round cross section, sized to Dash 038 dimensions. It measures 2.625 inches inside diameter, 2.75 inches outside diameter, and 0.0625 inches thick. The silicone compound carries a Shore hardness of 70, rated hard, and handles a working temperature range from -80 degrees F to 450 degrees F. This range makes it appropriate for applications where standard nitrile or EPDM compounds fall short. It ships in a package of 10 units. Plumbers, HVAC technicians, and industrial maintenance trades stock this O-ring for static and low-dynamic sealing applications where wide thermal tolerance is the primary requirement.

This O-ring suits residential and light commercial sealing applications involving oils, chemicals, and solvents where silicone is an acceptable compound. It performs well in dry-heat environments and offers good resistance to weather and ozone degradation. Typical install scenarios include pipe unions, valve stems, pump housings, and equipment access covers where a Dash 038 cross-section fits the groove. It is not recommended as a primary seal in systems with heavy petroleum oil exposure, as silicone has limited oil resistance. The 10-piece package quantity supports bench-stock and service-van inventory for trades that encounter this size regularly.

Key Features

• Wide temperature range: -80 degrees F to 450 degrees F continuous service

• Round cross section conforms to Dash 038 sizing standard
• Good weather and ozone resistance for outdoor or exposed installations
• Compatible with oils, chemicals, and solvents within silicone compound limits
• Packaged in quantities of 10 for convenient bench and van stock

Compatibility

Designed as an OEM-style replacement or service seal for any static or low-dynamic application requiring a Dash 038 silicone O-ring with a 2.625-inch inside diameter and 2.75-inch outside diameter.

Installation Notes

Plumbers and HVAC technicians should isolate and depressurize the system and drain any fluid before replacing an O-ring. Clean the groove of debris and inspect for damage before seating the new ring. Avoid stretching the O-ring excessively during installation; a thin film of compatible lubricant helps with seating without compromising the seal. Follow applicable IPC or IFGC provisions for the system type being serviced.
