Value Collection ZMSCS70932 Silicone O-ring Dash 932

Product Description

The VALUE COLLECTION ZMSCS70932 is a Dash 932 silicone O-ring designed for static and dynamic sealing applications that demand reliable performance across a wide temperature range. Measuring 2.337 inches inside diameter, 2.573 inches outside diameter, and 0.118 inches thick, this round cross-section ring is classified as an O-Ring Boss (ORB) gasket for use with straight-thread tube fittings. The silicone compound delivers good dry heat resistance and strong weather and ozone resistance, with a hardness rating of 70 Shore A. Each package contains 10 rings. Licensed plumbers, HVAC technicians, and pipefitters commonly install these seals.

This O-ring is suited for systems exposed to temperature extremes ranging from -80 degrees F to 450 degrees F, making it appropriate for HVAC equipment, pneumatic lines, and other mechanical assemblies where conventional rubber compounds may fail. Its function as an O-Ring Boss gasket positions it specifically for straight-thread tube fitting connections found in both residential and light commercial mechanical systems. Note that this compound offers only limited oil resistance, so it should not be specified for petroleum-fluid service without verifying compatibility with the fluid being sealed.

• 70 Shore A hardness for firm compression without excessive installation force
• O-Ring Boss (ORB) gasket geometry sized for straight-thread tube fittings
• Good weather and ozone resistance for exposed or outdoor mechanical connections
• Sold in a 10-piece package with a minimum order quantity of 1 package

Compatibility

Designed as a Dash 932 O-Ring Boss gasket for straight-thread tube fittings requiring a 2.337-inch inside diameter silicone seal. Verify fitting thread size and groove dimensions before installation to confirm fitment.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters. Depressurize and isolate the line before removing the existing seal and inspect the fitting groove for nicks or corrosion that could compromise the new seal. Lubricate the O-ring with a compatible silicone-based grease before seating it in the groove. Do not use petroleum-based lubricants with silicone O-rings, as they can degrade the compound over time.
