Value Collection ZBD16300-9 Nbr O-ring 90 Shore a Extra Hard

Product Description

The VALUE COLLECTION ZBD16300-9 is a nitrile butadiene rubber (NBR) O-ring with a round cross section designed for sealing applications across plumbing, HVAC, and fluid system maintenance. Rated at 90 Shore A hardness, this extra-hard O-ring holds up in demanding service conditions where softer compounds would deform under pressure or mechanical load. It operates across a temperature range of -40 degrees F to 275 degrees F, making it suitable for both cold and moderate-heat environments. Licensed trades and experienced technicians reach for NBR O-rings when sealing petroleum-based fluids, water, and hydraulic media.

This O-ring fits standard sealing grooves in residential and light commercial plumbing fittings, HVAC refrigerant-side connections, compressor ports, and fluid system couplings. The extra-hard 90 Shore A durometer makes it a practical choice where extrusion resistance is a priority, such as high-pressure joints or wide groove clearances. It is sold individually and must be ordered in multiples of 15 units minimum.

Key Features

• Nitrile butadiene rubber (NBR) construction resists petroleum-based fluids, water, and hydraulic media
• 90 Shore A extra-hard durometer provides strong extrusion resistance under pressure
• Round cross section for standard O-ring groove fitment
• Wide service temperature range: -40 degrees F to 275 degrees F
• Lightweight at 0.01 pounds per unit

Compatibility

Designed as a general-purpose NBR O-ring replacement suitable for standard O-ring grooves in plumbing, HVAC, and fluid handling equipment where nitrile rubber compound and 90 Shore A hardness meet the application requirements.

Installation Notes

O-ring installation is typically performed by licensed plumbers, HVAC technicians, or pipefitters as part of fitting assembly or component overhaul. Always depressurize and drain the system before removing or replacing O-rings. Inspect the seating groove for burrs, scoring, or debris before installing the new O-ring. Do not roll or twist the O-ring during installation, and avoid using sharp tools that may nick the sealing surface.
