Value Collection ZBD16300-4 Nbr O-ring 90 Durometer

Product Description

The VALUE COLLECTION ZBD16300-4 is a nitrile butadiene rubber (NBR) O-ring with a round cross section and an extra hard 90 durometer rating. NBR compound provides strong resistance to petroleum-based fluids, hydraulic oils, and fuels, making this O-ring a reliable sealing solution in demanding fluid-handling applications. The extra hard durometer rating suits high-pressure environments where softer compounds would extrude or deform. Licensed plumbers, HVAC technicians, and industrial maintenance techs regularly specify NBR O-rings for threaded connections, valve stems, pump housings, and hydraulic fittings where oil or fuel contact is expected.

This O-ring is suited for use in plumbing, HVAC, hydraulic, and light industrial systems operating across a wide temperature range. The -40 degrees F minimum working temperature allows service in cold-climate installations and refrigeration-adjacent applications, while the 275 degrees F maximum working temperature covers most hot-water and hydraulic system demands. It is not FDA approved, so it is not intended for food-contact or potable-water service lines where food-grade or NSF-listed compounds are required.

Key Features

• Nitrile butadiene rubber (NBR) construction resists petroleum oils, hydraulic fluids, and fuels
• Extra hard 90 Shore A durometer rating reduces extrusion risk in high-pressure assemblies
• Round cross section for standard groove compatibility
• Operating temperature range: -40 degrees F to 275 degrees F
• Not FDA approved — suitable for industrial, HVAC, and non-food-contact plumbing applications

Compatibility

Designed as an OEM-style replacement or service O-ring for industrial fluid-handling equipment, hydraulic assemblies, HVAC valves, and plumbing connections that call for a round-cross-section NBR seal.

Installation Notes

Licensed plumbers and HVAC or industrial service technicians typically install O-rings of this type. Isolate and depressurize the system fully before removing any fitting or valve that retains this seal. Inspect the mating groove for nicks, burrs, or corrosion before seating the new O-ring, and apply a compatible lubricant to prevent twisting or rolling during assembly. Do not overtighten fittings, as excess compression can damage even a high-durometer ring.
