Value Collection ZMSCS70FDA320 O-ring Dash 320 Silicone

Product Description

The VALUE COLLECTION ZMSCS70FDA320 is a Dash 320 silicone O-ring with a round cross section, designed to provide reliable static and dynamic sealing in systems that demand wide temperature range performance. Measuring 1.1 inches inside diameter, 1.5 inches outside diameter, and 0.1875 inches thick, this O-ring is manufactured from FDA-compliant silicone with a Shore A hardness of 70. It is rated for service from -80 degrees F to 450 degrees F, making it well suited for high-heat and outdoor exposure applications. The red color and FDA-compliant material make it appropriate for food-processing, sanitary, and general industrial environments.

This O-ring is used in plumbing, HVAC, food and beverage equipment, chemical handling, and general industrial applications where silicone sealing material is specified. Its good weather and ozone resistance makes it a practical choice for outdoor or exposed installations. The limited oil resistance of silicone should be factored in when selecting this O-ring for petroleum-based fluid systems. It is sold in a package quantity of 10, with a minimum order quantity of 1 package.

Compatibility

Designed as a Dash 320 standard O-ring replacement for use in grooves or fittings requiring a 1.1-inch ID, 1.5-inch OD, 0.1875-inch cross-section silicone seal in food service, HVAC, plumbing, and general industrial equipment.

Installation Notes

O-rings in this size class are typically installed by plumbers, HVAC technicians, or maintenance mechanics. Inspect the mating groove for burrs, debris, or wear before installation. Lubricate with a compatible, application-appropriate lubricant — avoid petroleum-based greases with silicone compounds, as they may cause swelling. Verify groove dimensions conform to Dash 320 specifications before installation to ensure proper compression and sealing.
