Value Collection BDNA-9334 O-ring 14in Id 19in Od Nbr

Product Description

The VALUE COLLECTION BDNA-9334 is a large-diameter nitrile butadiene rubber (NBR) O-ring with a 14-inch inside diameter, 19-inch outside diameter, and a 2.5-inch cross-section thickness. NBR compound provides solid resistance to petroleum-based fluids, hydraulic oils, and common industrial lubricants, making this O-ring a reliable sealing element in demanding fluid-handling applications. The round cross-section profile seats consistently in standard grooves, maintaining a reliable face or radial seal under compression. Installation is typically performed by millwrights, maintenance mechanics, or licensed plumbers depending on the application.

This O-ring is suited for large-bore sealing applications in industrial machinery, hydraulic cylinders, large-diameter pipe flanges, pump housings, and heavy equipment fluid systems. The NBR material performs across a broad range of operating temperatures and holds up well against aliphatic hydrocarbons and water-based fluids. Applications may include industrial processing equipment, agricultural machinery, and large HVAC or plumbing assemblies that require a robust static or low-cycle dynamic seal at this diameter range.

Key Features

• 14-inch inside diameter and 19-inch outside diameter for large-bore sealing applications
• 2.5-inch cross-section thickness provides substantial compression range in deep groove profiles
• Nitrile butadiene rubber (NBR) compound offers strong resistance to petroleum oils, hydraulic fluids, and water
• Round cross-section seats uniformly in standard O-ring grooves for consistent sealing force
• Metric-dimensioned part suitable for metric groove specifications

Compatibility

Designed as a standard NBR O-ring replacement for large-bore sealing applications requiring a 14-inch inside diameter and 19-inch outside diameter with a 2.5-inch round cross section. Verify groove dimensions against equipment manufacturer specifications before installation.

Installation Notes

Depressurize and isolate the system completely before removing the existing seal or installing a new O-ring. Inspect the groove for nicks, burrs, or corrosion that could damage the new seal or cause leakage at startup. A light coat of compatible lubricant — matched to the system fluid — may be applied to ease seating without overstretching the O-ring. Follow applicable equipment manufacturer torque and assembly procedures when closing flanges or housings.
