Value Collection ZMSCS70FDA334 Silicone O-ring Dash 334

Product Description

The VALUE COLLECTION ZMSCS70FDA334 is a Dash 334 silicone O-ring designed for static and dynamic sealing applications across HVAC, plumbing, chemical processing, and food-grade equipment. The round cross-section profile seats reliably in standard dash-series grooves. Manufactured from FDA-compliant silicone with a Shore A hardness of 70, this O-ring handles a wide service temperature range of -80 degrees F to 450 degrees F. It carries FDA approval for use in food-contact and sanitary environments. The red silicone material offers good dry heat resistance, weather resistance, and ozone resistance, making it a practical choice where thermal cycling or outdoor exposure is a factor.

This O-ring is suited for residential and commercial installations where sealing integrity must hold across wide temperature swings. Typical applications include HVAC equipment seals, pump housings, valve assemblies, and plumbing connections exposed to oils, certain chemicals, or solvents. The FDA-compliant silicone formulation also qualifies it for food processing and potable water system use where material certification is required. Each package contains 10 O-rings, sold in multiples of 1 package.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical technician following applicable system shutdown and depressurization procedures before replacing any seal. Inspect the mating groove for damage, debris, or corrosion before seating the O-ring. Lubricate the O-ring with a compatible lubricant approved for use with silicone elastomers and the system media. Avoid twisting or stretching the O-ring beyond its natural diameter during installation.
