Value Collection ZBD9500-219 Viton O-ring Dash 219

Product Description

The VALUE COLLECTION ZBD9500-219 is a Dash 219 Viton O-ring with a round cross section, designed for sealing applications in fluid and pneumatic systems. It measures 1.31 inches inside diameter, 1.56 inches outside diameter, and 0.125 inches thick. Made from Viton fluoroelastic material, this O-ring offers strong resistance to heat, oils, fuels, and many chemicals. It carries a hardness rating of 75 Shore A, placing it in the hard range, which supports reliable sealing under compression. Licensed plumbers, HVAC technicians, and industrial maintenance professionals commonly use this size in valve, pump, and fitting assemblies.

This O-ring is suited for residential and commercial plumbing, HVAC refrigerant circuits, hydraulic systems, and general industrial fluid handling where elevated temperatures or chemical exposure are factors. The Viton material handles service temperatures from -15 degrees F to 400 degrees F, making it appropriate for high-temperature fluid lines, steam-adjacent assemblies, and fuel system joints where standard nitrile or EPDM compounds fall short.

Installation Notes

Shut off all fluid or pneumatic pressure to the system before removing the old O-ring or installing a replacement. Clean the seating groove thoroughly and inspect it for scoring or damage before fitting the new O-ring. Do not use sharp tools that may nick the sealing surface; finger pressure or a plastic pick is preferred for seating. Verify compatibility of the Viton compound with the specific media being sealed before installation.
