Value Collection ZMSCS70FDA244 O-ring Dash 244 Silicone Fda

Product Description

The VALUE COLLECTION ZMSCS70FDA244 is a Dash 244 silicone o-ring designed for static and dynamic sealing applications where wide temperature range and dry heat resistance are required. Manufactured from red silicone with a 70 Shore A hardness rating and a round cross section, this o-ring measures 4.234 inches inside diameter, 4.5 inches outside diameter, and 0.125 inches thick. It carries FDA-compliant material designation, making it suitable for food-processing, pharmaceutical, and sanitary fluid-handling environments. Licensed plumbers, pipefitters, and maintenance technicians working on process piping, pumps, and fluid-handling assemblies are the primary installers.

This o-ring is appropriate for residential and commercial applications involving exposure to oils, chemicals, and solvents where a broad service temperature range is critical. Its silicone compound performs from -80 degrees F to 450 degrees F, making it well suited for high-heat process equipment, HVAC fluid circuits, and sanitary piping systems. Note that silicone offers limited resistance to petroleum-based oils under sustained dynamic conditions; confirm fluid compatibility before installation. Sold in packages of 5.

Key Features

Compatibility

Designed as a Dash 244 standard o-ring replacement for grooves and glands sized to accept a 4.234 inches ID, 4.5 inches OD, 0.125 inches cross-section silicone seal. Confirm groove dimensions and fluid compatibility before installation.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or qualified maintenance technicians. Depressurize and drain the system completely before removing the old o-ring. Inspect the groove for nicks, burrs, or corrosion that could compromise the seal; clean thoroughly before seating the new ring. Apply a compatible, system-fluid-safe lubricant to ease installation and prevent pinching or rolling of the o-ring during assembly.
