Value Collection ZBD9500-121 O-ring Dash 121 Viton

Product Description

The VALUE COLLECTION ZBD9500-121 is a Viton O-ring with a round cross section, designed for static and dynamic sealing applications across plumbing, HVAC, hydraulic, and fluid-handling systems. It carries a Dash 121 designation with a 1.060-inch inside diameter, 1.250-inch outside diameter, and a 0.094-inch cross-section thickness. The Viton (FKM) compound provides strong resistance to petroleum-based fluids, fuels, and elevated temperatures, making it suitable for demanding service environments. Licensed tradespeople and maintenance technicians install this style of O-ring wherever a dependable face seal or radial seal is required.

This O-ring fits Dash 121 groove dimensions per standard AS568 sizing. It is used in residential and commercial applications including valve bodies, pump housings, fittings, and manifold connections. Its Viton compound makes it a common choice in systems handling oils, fuels, refrigerants, and other aggressive media where a standard nitrile (Buna-N) compound would degrade prematurely. Minimum order quantity is 25 pieces.

Installation Notes

O-ring installation should be performed by a qualified technician following the equipment manufacturer's service procedures. Always depressurize and isolate the system before replacing any seal. Inspect the groove for burrs, corrosion, or wear before seating the new O-ring, and apply a compatible lubricant to ease installation and prevent tearing. Avoid rolling or twisting the O-ring during placement.
