Value Collection ZMSCS70FDA337 O-ring Dash 337 Silicone Fda

Product Description

The VALUE COLLECTION ZMSCS70FDA337 is a Dash 337 silicone o-ring with a round cross section, designed for static and dynamic sealing applications across a wide range of operating conditions. It measures 2.975 inches inside diameter and 3.375 inches outside diameter, with a thickness of 0.1875 inches (3/16 inches). The compound carries a Shore A hardness rating of 70 and is manufactured from FDA-compliant silicone material, making it suitable for installations where food-grade or sanitary compliance is required. Licensed plumbers, pipefitters, and mechanical technicians typically install this o-ring in flanged connections, pump housings, and fluid handling assemblies.

This o-ring is suited for residential and commercial applications where exposure to wide temperature swings, dry heat, weather, and ozone is expected. Its silicone compound provides good dry heat resistance and weather and ozone resistance, though oil resistance is limited. Typical install scenarios include water treatment equipment, food processing lines, chemical handling systems, and HVAC fluid circuits where FDA-compliant sealing material is specified. Each package contains 5 o-rings.

Key Features

• FDA-compliant silicone material meets food-grade and sanitary application requirements
• Wide service temperature range from -80 degrees F to 450 degrees F
• Shore A hardness of 70 provides a firm, reliable seal under compression
• Good weather and ozone resistance for outdoor or exposed installations
• Compatible with oils, chemicals, and solvents in limited concentrations
• Round cross section for consistent sealing contact in standard o-ring grooves

Compatibility

Designed as a standard Dash 337 o-ring replacement for equipment using a 2.975-inch ID groove profile. Compatible with systems handling oils, chemicals, and solvents where silicone compound and FDA-compliant material are acceptable. Verify groove dimensions and fluid compatibility before installation.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or mechanical technician. Depressurize and drain the system fully before removing the old o-ring. Lightly lubricate the o-ring with a compatible, FDA-approved lubricant before seating to prevent tearing during assembly. Do not use petroleum-based lubricants with silicone compound, as they may degrade the seal over time.
