Value Collection ZBD9500-133 Viton O-ring Dash 133

Product Description

The VALUE COLLECTION ZBD9500-133 is a Dash 133 Viton O-ring with a round cross section, designed for static and dynamic sealing applications across plumbing, HVAC, hydraulic, and industrial systems. With an inside diameter of 1.81 inches, an outside diameter of 2 inches, and a thickness of 0.0937 inches, this O-ring provides a reliable compression seal. Viton material delivers strong resistance to heat, fuels, oils, and many chemicals, making it well suited for high-temperature service environments. Hardness is rated at 75 Shore A. Installation is handled by licensed plumbers, HVAC technicians, or industrial maintenance technicians depending on application.

This O-ring is appropriate for use in residential and commercial sealing applications where elevated temperature resistance is required. The Viton compound performs across a working temperature range of -15 degrees F to 400 degrees F, supporting use in hot fluid systems, refrigeration circuits, fuel-handling assemblies, and general mechanical sealing duties where standard Buna-N compounds may degrade. Sold individually with a minimum order quantity of 10 units.

Compatibility

Designed as a standard Dash 133 O-ring replacement suitable for any gland or groove machined to AS568 Dash 133 dimensional specifications across plumbing, HVAC, hydraulic, and industrial equipment.

Installation Notes

Depressurize and drain the system before removing the old O-ring to prevent fluid release and injury. Inspect the gland groove for nicks, corrosion, or debris before seating the new O-ring. Apply a compatible lubricant sparingly to ease installation and avoid rolling or twisting the cross section during assembly. Viton O-rings are not compatible with ketones or certain glycol-based fluids — verify chemical compatibility before installation.
