Value Collection ZMSCS70FDA247 Silicone O-ring Dash 247

Product Description

The VALUE COLLECTION ZMSCS70FDA247 is a silicone O-ring with a round cross section, rated Shore 70A hardness, and sized to Dash 247 standards. The inside diameter measures 4.625 inches, the outside diameter measures 4.875 inches, and the thickness is 0.125 inches (3.53 mm). This O-ring is manufactured from FDA-compliant silicone and is suited to static and dynamic sealing applications that require broad temperature tolerance. It is sold in a package of 5 units. Plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal across fluid, air, and process system connections.

This O-ring is appropriate for residential and commercial applications requiring a wide operating temperature range. The silicone compound provides good dry heat resistance, solid weather and ozone resistance, and limited oil resistance. It performs reliably across a service range of -80 degrees F to 450 degrees F, making it a practical choice for high-temperature or outdoor-exposed sealing points in HVAC, plumbing, and food-grade process equipment where FDA-compliant materials are required.

Installation Notes

O-rings of this type are installed by licensed plumbers, HVAC technicians, or qualified maintenance personnel. Always de-energize equipment and relieve system pressure before replacing any seal. Inspect the mating groove for damage, debris, or corrosion prior to installation. Avoid twisting or rolling the O-ring during seating to maintain cross-section integrity.
