Value Collection ZMSCS70FDA332 Silicone O-ring Dash 332

Product Description

The VALUE COLLECTION ZMSCS70FDA332 is a Dash 332 silicone O-ring with a round cross section, designed for static and dynamic sealing applications across plumbing, HVAC, and fluid-handling systems. It measures 2.375 inches inside diameter, 2.75 inches outside diameter, and 0.1875 inches thick. The silicone compound carries an FDA-compliant material designation and a Shore A hardness of 70, placing it in the hard hardness rating category. Its operating temperature range spans -80 degrees F to 450 degrees F, making it well suited for high-heat or wide-swing thermal environments where standard BUNA-N or EPDM compounds would degrade. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this O-ring type in pumps, valves, fittings, and manifold assemblies.

This O-ring is appropriate for residential and commercial applications where exposure to oils, chemicals, solvents, and dry heat is expected. The silicone material provides good weather and ozone resistance, making it suitable for outdoor equipment, rooftop HVAC units, and systems that cycle through broad temperature ranges. Its FDA-compliant silicone compound also qualifies it for use in food-processing and potable-water adjacent equipment where material safety documentation is required. Sold in packages of 10 with a minimum order quantity of 1 package.

Key Features

• Good weather, ozone, and dry heat resistance
• Round cross section for consistent sealing in standard O-ring grooves
• Compatible with oils, chemicals, and solvents

Compatibility

Designed as an OEM-style replacement or service seal for Dash 332 O-ring groove applications in pumps, valves, fittings, and fluid-handling assemblies requiring an FDA-compliant silicone compound.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Shut off all pressure and fluid flow to the assembly before removing the old O-ring and seating the replacement. Inspect the groove for nicks, corrosion, or debris that could compromise the seal. Do not use petroleum-based lubricants with silicone O-rings; use a silicone-compatible lubricant where lubrication is needed during installation.
