Bien Air Motor Nozzle O-Ring, 8.1 x 0.73 mm, 10/Pk

Bien Air Motor Nozzle O-Rings are precision-engineered replacement seals sized 8.1 mm inner diameter with a 0.73 mm cross-section, designed to fit within the motor nozzle and seal the drive air tube to the handpiece attachment. Made from durable elastomer, they withstand repeated autoclave sterilization while maintaining the air, water, and exhaust separation needed to prevent internal leaks, torque loss, and inconsistent spray cooling. Each pack contains 10 O-rings for routine maintenance of compatible Bien Air electric and air motors.
