Value Collection ZMSCS70034 Silicone O-ring Dash 034

Product Description

The VALUE COLLECTION ZMSCS70034 is a silicone O-ring with a round cross section, designed for static and dynamic sealing applications across HVAC, plumbing, and industrial systems. It measures 2.125 inches inside diameter, 2.25 inches outside diameter, and 0.0625 inches thick, conforming to the AS568 Dash 034 standard. Rated from -80 degrees F to 450 degrees F, this O-ring suits applications that demand a wide temperature range and reliable dry heat resistance. Each package contains 25 rings. The white silicone construction offers good weather and ozone resistance, making it a practical choice for recurring maintenance and repair work.

This O-ring is used in applications where exposure to oils, chemicals, and solvents is a consideration, though silicone carries limited oil resistance and should be selected with that trade-off in mind. Typical install scenarios include flange seals, pipe fittings, valve stems, and equipment housings in residential and light commercial HVAC and plumbing systems. The Dash 034 sizing is a standard reference used across many OEM and aftermarket components, making this a common replacement ring stocked by service technicians for field repairs.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or maintenance professionals. Always depressurize and de-energize the system before replacing any O-ring to prevent injury or fluid release. Lubricate the O-ring with a compatible lubricant before seating to prevent tearing during assembly. Inspect the groove for damage or debris before installing the new ring.
