Nonin 8500 Handheld Pulse Oximeter Parts & Accessories

The Nonin 8500 is a durable handheld pulse oximeter valued in clinical, EMS, and portable-care settings for its reliable SpO₂ and pulse rate readings under demanding conditions. Because these units log years of hard field use, keeping the right replacement parts on hand is what keeps a proven device in service rather than sidelined by a small, worn component.

This collection covers accessories and service parts for the Nonin 8500 line, including the Nonin 8500 Rubber Bumper (1271-000). The bumper is the protective outer cushion that absorbs the shocks of daily handling and transport — the piece most likely to crack, split, or wear loose over time. Replacing a degraded bumper restores the housing's drop protection and grip, extending the working life of an instrument that is otherwise fully functional.

Buyers sourcing these parts are typically maintaining an existing fleet: biomed departments, ambulance services, and facilities standardizing on Nonin equipment. If that describes you, the questions that matter are compatibility and authenticity. The 1271-000 is a genuine Nonin component matched specifically to the 8500 chassis, so it seats correctly without the fit issues common to universal aftermarket parts. Confirming your model number before ordering ensures the bumper matches your unit's exact housing revision.
