Value Collection ZBD10174-5 Nbr O-ring 90 Shore a

Product Description

The VALUE COLLECTION ZBD10174-5 is a nitrile butadiene rubber (NBR) o-ring with a round cross section, rated at 90 Shore A hardness — classified as extra hard. NBR o-rings are widely used in fluid and pneumatic systems to provide static or dynamic seals at joints, fittings, and valve seats. This part is suited for applications requiring resistance to petroleum-based oils, fuels, and hydraulic fluids. It operates across a wide temperature range of -40 degrees F to 275 degrees F, making it appropriate for both low-temperature startup conditions and elevated service environments. Plumbers, HVAC technicians, and industrial maintenance trades install this type of component during routine sealing work on pumps, compressors, and fluid-handling assemblies.

This o-ring is applicable to residential and light commercial plumbing, HVAC refrigerant-side components, hydraulic systems, and general industrial fluid connections where a high-durometer NBR seal is specified. The extra hard 90 Shore A rating makes it particularly suited for high-pressure applications where softer compounds would extrude under load. It is not FDA approved and should not be used in food-contact or potable water lines requiring NSF or FDA-compliant materials. Installers should confirm the groove dimensions and cross-section diameter match the manufacturer specifications for the assembly being serviced before installation.

Key Features

• Nitrile butadiene rubber (NBR) construction resists petroleum-based oils, fuels, and hydraulic fluids
• Round cross section for standard o-ring groove fitment
• 90 Shore A hardness rating — extra hard — suitable for high-pressure sealing applications
• Wide service temperature range: -40 degrees F to 275 degrees F
• Not FDA approved — for industrial and mechanical fluid systems only

Compatibility

Designed as an OEM-style replacement or service seal for industrial, HVAC, plumbing, and hydraulic assemblies requiring a high-durometer NBR round cross-section o-ring. Confirm groove dimensions prior to installation.

Installation Notes

Installation should be performed by a qualified plumber, HVAC technician, or mechanical maintenance professional. Depressurize and de-energize the system and relieve all fluid pressure before replacing any seals or o-rings. Lubricate the o-ring with a compatible fluid or assembly lubricant before seating to prevent tearing during installation. Do not overstretch the o-ring during installation, as this reduces sealing effectiveness and service life.
