Value Collection ZBD10174-3 O-ring Dash 219 Nbr 90 Shore

Product Description

The VALUE COLLECTION ZBD10174-3 is a Dash 219 O-ring manufactured from Nitrile Butadiene Rubber (NBR) with a round cross section. Rated at 90 Shore A hardness, this extra-hard O-ring is built for sealing applications that demand firm compression resistance and good resistance to petroleum-based fluids. It performs across a wide service temperature range of -40 degrees F to 275 degrees F, making it suitable for both low-temperature startup conditions and elevated operating environments. Plumbers, HVAC technicians, and industrial maintenance professionals install this type of O-ring as a sealing element in fittings, valves, pumps, and fluid system connections.

The ZBD10174-3 Dash 219 O-ring is commonly used in hydraulic, pneumatic, and fluid transfer systems where a reliable static or dynamic seal is needed. Its NBR compound offers good compatibility with oils, fuels, and many water-based fluids. The extra-hard 90 Shore A rating suits it for higher-pressure sealing points where softer elastomers would extrude or deform under load. This O-ring is appropriate for both residential and light commercial plumbing and HVAC service work as well as industrial maintenance and repair applications.

Key Features

• Dash 219 standard sizing for straightforward cross-reference and replacement
• Nitrile Butadiene Rubber (NBR) compound with good resistance to petroleum-based fluids and oils
• Round cross section for consistent seating in standard O-ring grooves
• Extra-hard 90 Shore A durometer for firm compression resistance in higher-pressure applications
• Wide service temperature range: -40 degrees F to 275 degrees F

Compatibility

Designed as a standard Dash 219 O-ring replacement suitable for use in valves, fittings, pumps, and fluid system assemblies that accept a Dash 219 cross-reference size in NBR material.

Installation Notes

Installation should be performed by a qualified technician with the system depressurized and isolated from fluid supply before removing the old seal. Inspect the O-ring groove for burrs, corrosion, or damage before installing the new ring. Apply a compatible lubricant to the O-ring during installation to prevent tearing or rolling during assembly. Avoid overstretching the O-ring; use proper installation tools where the groove geometry requires it.
