Value Collection ZMSCS70FDA230 Silicone O-ring Dash 230

Product Description

The VALUE COLLECTION ZMSCS70FDA230 is a Dash 230 silicone O-ring with a round cross section, designed for static and dynamic sealing applications across a wide range of industrial and fluid-handling systems. With a 2.484-inch inside diameter, a 2.75-inch outside diameter, and a 0.125-inch (3.53 mm) cross-section thickness, this O-ring seats into standard AN/MS Dash 230 grooves. The silicone compound carries a Shore 70 hardness rating and FDA-compliant material certification, making it suitable for food-processing, pharmaceutical, and potable-water applications in addition to general industrial use. Each order ships in a package of 10 pieces.

This O-ring is appropriate for use in plumbing, HVAC, food and beverage equipment, chemical processing lines, and pool and water-treatment systems where broad temperature tolerance and ozone resistance are priorities. The silicone material performs across a service range of -80 degrees F to 450 degrees F, making it a practical choice for both heated and refrigerated process piping. Installers working on sanitary systems will note the FDA-compliant silicone formulation. The red color aids visual identification during inspection and maintenance. Oil and solvent exposure should be evaluated against service conditions, as this compound offers only limited oil resistance.

Key Features

• FDA-compliant silicone material suitable for food, pharmaceutical, and potable-water contact
• Service temperature range of -80 degrees F to 450 degrees F for wide thermal tolerance
• Shore 70 hardness provides a firm, reliable seal in standard Dash 230 grooves
• Good resistance to ozone, weathering, and dry heat
• Round cross section conforms to standard AN/MS Dash 230 O-ring groove dimensions
• Red color allows easy visual identification during inspection

Compatibility

Designed as a standard Dash 230 O-ring replacement compatible with any AN/MS-dimensioned groove requiring a 2.484-inch ID, 2.75-inch OD, and 0.125-inch cross-section thickness in silicone compound. Compatible with oils, chemicals, and solvents within the material limits noted; limited oil resistance should be factored into fluid compatibility reviews.

Installation Notes

Installation is performed by plumbers, HVAC technicians, and equipment maintenance technicians. Always depressurize and isolate the system, drain any fluid, and confirm the groove dimensions match Dash 230 specifications before seating the O-ring. Avoid using petroleum-based lubricants with silicone O-rings; use a silicone-compatible assembly lubricant only. Inspect the groove for nicks or burrs that could damage the sealing surface before reinstalling.
