Value Collection ZMSCS70FDA240 Silicone O-ring Dash 240 5-pack

Product Description

The VALUE COLLECTION ZMSCS70FDA240 is a Dash 240 silicone O-ring designed for static and dynamic sealing applications across a broad operating temperature range. It measures 3.734 inches inside diameter by 4 inches outside diameter with a 0.125-inch (1/8 inch) round cross-section thickness. Rated at 70 Shore A hardness, this O-ring is manufactured from FDA-compliant silicone material, making it suitable for food processing, pharmaceutical, and sanitary equipment applications. Each package contains 5 O-rings. Licensed plumbers, industrial maintenance techs, and equipment service professionals typically specify and install this part.

This O-ring is suited for applications requiring reliable sealing across wide temperature swings, with a rated range of -80 degrees F to 450 degrees F. The silicone compound provides good resistance to dry heat, weather, and ozone exposure. It carries limited oil resistance and is compatible with certain oils, chemicals, and solvents as noted by the manufacturer. The FDA-compliant material designation makes it appropriate for use in food-grade and sanitary fluid handling systems where material certification is required.

Installation Notes

Power down or depressurize and isolate the system before replacing any O-ring seal. Inspect the groove seat for scoring, corrosion, or debris before installing the new O-ring. Lubricate the O-ring with a compatible, system-appropriate lubricant prior to seating to prevent tearing during assembly. Do not use petroleum-based lubricants with silicone O-rings unless confirmed compatible with the system fluid.
