Value Collection ZMSCS70FDA113 Silicone O-ring Dash 113

Product Description

The VALUE COLLECTION ZMSCS70FDA113 is a Dash 113 silicone O-ring with a round cross section, sized at 0.549 inches inside diameter and 0.750 inches outside diameter with a 0.0937-inch thickness. Rated at 70 Shore A hardness, this O-ring is manufactured from FDA-compliant silicone material, making it suitable for food-processing, sanitary, and pharmaceutical fluid-handling applications. The silicone compound provides a working temperature range of -80 degrees F to 450 degrees F, delivering reliable sealing performance across extreme thermal cycles. HVAC technicians, plumbers, and industrial maintenance professionals install this O-ring wherever dry heat resistance, weather resistance, and ozone resistance are required.

This O-ring is well suited for use in residential and commercial plumbing systems, HVAC refrigerant circuits, food-service equipment, chemical-handling assemblies, and sanitary process lines where FDA-compliant sealing materials are required. The silicone compound offers good resistance to weathering, ozone, and dry heat, though oil resistance is limited. Applications requiring a wide temperature range and clean-service compatibility are the primary use case. Sold in a package quantity of 100, this O-ring is appropriate for service shops and contractors maintaining inventory for routine seal replacements.

Compatibility

Designed as a standard Dash 113 O-ring replacement for any application requiring a 0.549-inch ID by 0.750-inch OD by 0.0937-inch thick FDA-compliant silicone seal, including sanitary plumbing fittings, food-service equipment, and chemical-handling systems.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or industrial maintenance professional. De-energize or depressurize the system and relieve all fluid pressure before removing the existing O-ring. Inspect the seating groove for nicks, burrs, or debris before installing the replacement seal. Do not use petroleum-based lubricants with silicone O-rings; use a compatible silicone-based or food-grade lubricant if lubrication is required during assembly.
