Value Collection ZMSCS70FDA218 Silicone O-ring Dash 218

Product Description

The VALUE COLLECTION ZMSCS70FDA218 is a Dash 218 silicone O-ring designed for static and dynamic sealing applications across plumbing, HVAC, chemical handling, and food-grade systems. Manufactured from red silicone with a Shore A hardness of 70, this O-ring measures 1.234 inches inside diameter and 1.5 inches outside diameter with a 0.125-inch (1/8 inch) cross-section thickness. The round cross-section profile seats cleanly in standard AN/MS Dash 218 grooves. FDA compliant material construction makes it suitable for applications where contact with food, beverage, or potable water is a requirement. Each package contains 25 O-rings.

This O-ring is suited for residential and commercial plumbing, HVAC equipment sealing, pump and valve assemblies, and chemical processing lines. The wide service temperature range of -80 degrees F to 450 degrees F makes it appropriate for both low-temperature refrigeration environments and high-heat dry applications. Its resistance to weather and ozone makes it a practical choice for outdoor or exposed installations. Limited oil resistance should be considered when specifying for petroleum-fluid contact applications.

Compatibility

Designed as a standard Dash 218 O-ring replacement compatible with any application specifying a 1.234-inch ID, 1.5-inch OD, 0.125-inch thickness silicone O-ring in a round cross-section groove. Compatible with oils, chemicals, and solvents within the rated temperature range; note limited resistance to petroleum-based oils.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical tradesperson following applicable IPC or equipment manufacturer guidelines. Depressurize and drain the system completely before replacing any O-ring seal. Lightly lubricate the O-ring with a compatible, system-appropriate lubricant prior to installation to prevent tearing or roll during assembly. Do not stretch the O-ring beyond the groove diameter or use sharp tools that could nick the sealing surface.
