Value Collection ZBD16300 Nbr O-ring 90 Durometer

Product Description

The VALUE COLLECTION ZBD16300 is a nitrile butadiene rubber (NBR) O-ring with a round cross section and an extra-hard 90 durometer rating. It is designed to provide reliable sealing in fluid and gas systems across HVAC, plumbing, and industrial applications. The high durometer rating makes this O-ring well suited for high-pressure environments where a softer seal compound would deform or extrude. Rated for operating temperatures from -40 degrees F to 275 degrees F, this NBR compound handles petroleum-based fluids, hydraulic oils, and water-based media common in mechanical service work. Licensed tradespeople and maintenance technicians working on pumps, valves, fittings, and fluid lines will find this a standard sealing component.

This O-ring is used in residential and light commercial mechanical systems wherever a round cross-section sealing element is required. Typical applications include pump housings, valve bodies, threaded fittings, and hydraulic or pneumatic connections. The NBR compound provides good resistance to petroleum-based fluids, making it a common choice for refrigeration service valves, hydronic system fittings, and compressed-air line components. It is not FDA approved, so it is not intended for direct food-contact or potable-water-contact applications without additional verification of local code compliance.

Key Features

• Nitrile butadiene rubber (NBR) construction resists petroleum oils, hydraulic fluid, and water-based media
• 90 durometer extra-hard rating reduces extrusion risk under elevated pressure
• Round cross-section geometry for standard O-ring groove fitment
• Operating temperature range of -40 degrees F to 275 degrees F suits most mechanical service environments
• Not FDA approved — confirm application suitability before use in regulated systems

Compatibility

Designed as a standard round cross-section NBR O-ring replacement for use in pump, valve, fitting, and fluid-line assemblies requiring a 90 durometer sealing element.

Installation Notes

Installation is typically performed by licensed plumbers, HVAC technicians, or mechanical service professionals. Always depressurize and de-energize the system before replacing any O-ring seal. Inspect the mating groove for burrs, corrosion, or damage that could compromise the seal. Apply a compatible lubricant to the O-ring prior to installation to prevent tearing during assembly — use only lubricants rated compatible with NBR compound.
