Value Collection ZBD9500-231 Viton O-ring Dash 231

Product Description

The VALUE COLLECTION ZBD9500-231 is a Dash 231 Viton O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and pneumatic systems. It measures 2.63 inches inside diameter, 2.88 inches outside diameter, and 0.125 inches thick. The Viton (FKM) compound delivers broad chemical resistance and a wide service temperature range of -15 degrees F to 400 degrees F, making it well suited for applications where standard nitrile or EPDM compounds fall short. Hardness is rated at 75 Shore A, placing it in the hard category for firm, reliable compression sealing. Licensed plumbers, HVAC technicians, and industrial maintenance mechanics commonly install this type of O-ring.

This O-ring fits sealing applications across residential and commercial plumbing, HVAC refrigerant circuits, hydraulic systems, and industrial fluid handling where Dash 231 sizing is specified. Its Viton compound makes it appropriate for use with fuels, oils, and many aggressive chemicals at elevated temperatures. It is sold individually per package with a minimum order quantity of 5 units, which is typical for small O-ring SKUs used in service kits or repair stock.

Installation Notes

Shut down and depressurize the system completely before removing the old O-ring. Clean the groove thoroughly and inspect for damage or corrosion before seating the new ring. Apply a compatible O-ring lubricant rated for Viton compound to ease installation and prevent twisting. Do not roll or stretch the O-ring excessively during installation, as this can compromise the sealing surface.
