The VALUE COLLECTION ZBD9500-134 is a Viton O-ring with a round cross section, used to create fluid-tight seals in mechanical assemblies, hydraulic systems, and fluid handling equipment. With a 1.88-inch inside diameter, 2.06-inch outside diameter, and 0.0937-inch (3/32 inch) thickness, this Dash 134 O-ring meets standard sizing for quick cross-referencing. Viton material provides strong resistance to heat, oils, fuels, and many chemical media, making it a reliable choice for demanding service environments. Hardness is rated at 75 Shore A, placing it in the hard range for positive sealing under pressure.
This O-ring is suited for use in HVAC equipment, plumbing assemblies, hydraulic and pneumatic systems, and industrial fluid-handling applications where elevated temperatures or hydrocarbon exposure is a factor. The Dash 134 designation conforms to AS568 standard sizing, allowing straightforward identification and replacement across a wide range of OEM and aftermarket fittings. Licensed trades including HVAC technicians, plumbers, and industrial mechanics commonly stock standard dash-size O-rings for field service and preventive maintenance work.
Designed as a standard Dash 134 replacement O-ring for any application calling for an AS568-134 Viton seal with 1.88 inches ID, 2.06 inches OD, and 3/32 inch thickness.
De-energize and depressurize the system before removing the old O-ring. Inspect the O-ring groove for wear, scoring, or contamination before installing the replacement. Apply a thin, compatible lubricant to the O-ring prior to installation to prevent tearing during assembly. Avoid using petroleum-based lubricants with Viton if the application involves incompatible media.
