Value Collection ZBD16300-6 Nbr O-ring 90 Shore a

Product Description

The VALUE COLLECTION ZBD16300-6 is a round cross-section O-ring made from Nitrile Butadiene Rubber (NBR), rated at 90 Shore A hardness for extra-hard sealing applications. NBR compound delivers reliable resistance to oils, fuels, and hydraulic fluids across a working temperature range of -40 degrees F to 275 degrees F. This O-ring is suited for static and dynamic sealing tasks in fluid handling, pneumatic, and hydraulic systems. Plumbers, HVAC technicians, and industrial maintenance professionals install this type of seal in fittings, valves, pumps, and manifold assemblies where a firm, oil-resistant seal is required.

This O-ring fits into residential and commercial maintenance applications where NBR material is specified. The extra-hard 90 Shore A rating makes it appropriate for higher-pressure sealing environments where softer compounds would extrude or deform. It is commonly used in hydraulic fittings, fluid connectors, pump housings, and pneumatic valve assemblies. The round cross-section profile seats consistently in standard O-ring grooves. Note that this O-ring is not FDA approved and should not be used in food-processing or potable-water contact applications where FDA-compliant materials are required.

Key Features

• Nitrile Butadiene Rubber (NBR) construction resists oils, fuels, and hydraulic fluids
• 90 Shore A extra-hard rating suits higher-pressure and dynamic sealing environments
• Round cross-section seats consistently in standard machined O-ring grooves
• Wide service temperature range: -40 degrees F to 275 degrees F
• Not FDA approved — appropriate for industrial and mechanical fluid sealing applications

Compatibility

Designed as a standard NBR O-ring replacement for industrial, hydraulic, pneumatic, and mechanical fluid sealing assemblies that specify a round cross-section, extra-hard NBR compound.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or industrial maintenance mechanics. Depressurize and drain the system fully before removing any fitting or valve that retains an O-ring seal. Lubricate the O-ring with a compatible fluid or assembly lubricant prior to seating to prevent tearing during installation. Inspect the groove for burrs or damage before installing the new seal.
