Value Collection ZMSCS70FDA325 Silicone O-ring Dash 325

Product Description

The VALUE COLLECTION ZMSCS70FDA325 is a Dash 325 silicone O-ring designed for static and dynamic sealing applications across plumbing, fluid handling, and industrial equipment. The round cross-section profile seats reliably in standard AN/AS568 grooves. With a hardness rating of 70 Shore A and FDA-compliant silicone material, this O-ring suits systems where food-grade or chemical-contact compliance is required. It handles a working temperature range of -80 degrees F to 450 degrees F, making it a practical choice for high-heat and wide-swing thermal environments. Plumbers, HVAC technicians, and equipment service professionals install this type of seal when replacing worn or damaged O-rings in valves, pumps, manifolds, and fittings.

This O-ring is suited for residential and commercial applications where silicone elastomer is specified over Buna-N or EPDM. Its limited oil resistance makes it best matched to dry heat, steam, ozone-exposed, and chemical environments rather than petroleum-heavy hydraulic circuits. Compatible materials include oils in limited concentrations, chemicals, and solvents. The FDA-compliant material designation makes it appropriate for use in potable water systems, food processing equipment, and sanitary piping where regulatory compliance is required. Sold in a package quantity of 10, it supports standard service stock or single repair needs.

Compatibility

Designed as an OEM-style replacement or service seal for any application specifying an AN/AS568 Dash 325 O-ring in silicone elastomer. Verify groove dimensions and material compatibility before installation.

Installation Notes

Shut off fluid supply and depressurize the system before removing the old seal. Clean the groove thoroughly and inspect for scoring or damage that could compromise the new seal. Lubricate the O-ring with a compatible, non-petroleum lubricant such as silicone grease before seating. Follow applicable codes including IPC or IFGC as relevant to the system type, and confirm FDA compliance documentation if required by the jurisdiction or application.
