Value Collection ZBD9500-221 Viton O-ring Dash 221

Product Description

The VALUE COLLECTION ZBD9500-221 is a Viton O-ring with a round cross section, designed for static and dynamic sealing applications in fluid and pneumatic systems. It measures 1.44 inches inside diameter, 1.69 inches outside diameter, and 0.125 inches thick, conforming to Dash 221 sizing. Viton fluoroelastomer construction provides strong resistance to oils, fuels, hydraulic fluids, and a wide range of chemicals, making this O-ring suitable for demanding service environments. A Shore A hardness of 75 gives it a firm, reliable seat under compression. Licensed plumbers, HVAC technicians, and industrial mechanics commonly specify this part for sealing fittings, valves, and fluid system components.

This O-ring is suited for residential and commercial plumbing, HVAC refrigerant and hydraulic circuits, and general industrial fluid systems where elevated temperatures or chemical exposure require a fluoroelastomer seal. It performs across a rated temperature range of -15 degrees F to 400 degrees F, making it appropriate for both heating system connections and high-heat process plumbing. Minimum order quantity is 25 pieces.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or industrial mechanics. Depressurize and isolate the system before removing the old seal. Inspect the gland for scoring or damage before seating the new O-ring. Avoid twisting or pinching the O-ring during installation, and apply a compatible lubricant to aid seating without compromising seal integrity.
