DCI International Precision Comfort Syringe Button with Spring is used for replacing a single worn, sticky, or non-returning syringe button on a DCI Precision Comfort air/water syringe when only the button and spring component requires replacement rather than a full syringe repair requiring the complete 5-component Precision Comfort Repair Kit (PN 3635), allowing the clinician or dental assistant to restore the function of a single air or water button on the Precision Comfort syringe by replacing just the button and its spring without replacing the tip O-ring, adapter O-ring, and adapter spring components included in the full repair kit. The Precision Comfort syringe platform uses a patent-pending Precision Touch button design that provides a 45% softer button activation feel compared to standard syringe buttons, reducing the finger pressure required for air and water activation during the repeated syringe button depressions that occur throughout a full day of clinical procedures, and the PN 3637 Precision Comfort button-spring unit is specifically designed for the Precision Comfort syringe's Precision Touch button mechanism and is not interchangeable with the Quick-Clean syringe button (PN 3085) used in the Quick-Clean syringe platform.

The spring paired with the Precision Comfort button provides the spring return force pushing the button back to its extended resting position after each depression during air and water delivery at the chairside, and when this spring becomes fatigued or the button develops sticking or inconsistent return, replacing the button-and-spring unit restores the Precision Touch activation feel and spring return performance that characterizes the Precision Comfort syringe's clinical operation. Dental assistants, equipment technicians, and practice managers who maintain DCI Precision Comfort air/water syringes and require a single button with spring for targeted button replacement find DCI International Precision Comfort Syringe Button with Spring the single-unit Precision Touch button-spring replacement for their active Precision Comfort syringe maintenance program. ? Each pack contains 1 individual DCI International Precision Comfort Syringe Button with Spring, providing the single button-spring unit for replacing one air or water button on a Precision Comfort syringe. The single-unit pack format is appropriate when only one of the two syringe buttons on a Precision Comfort syringe requires replacement and the other button is functioning normally, providing the option to replace a single faulty button without purchasing the full 5-component repair kit when only the button component has failed.

For practices that need to replace both the air and water buttons simultaneously, two units of PN 3637 are required, or alternatively the DCI Precision Comfort Syringe Buttons and Repair Kit PN 3635 which includes 2 x PN 3637 button-spring units along with the tip O-ring, adapter O-ring, and adapter spring for a complete syringe overhaul. ? DCI International Precision Comfort Syringe Button with Spring works through its Precision Touch button design and spring assembly where the button seats within the Precision Comfort syringe body at the button port and the spring provides the return force during button release after each air or water delivery activation. The Precision Touch button geometry and spring rate provide the 45% softer activation force compared to standard button designs, maintaining the reduced button depression resistance that Precision Comfort syringe users rely on throughout the clinical day for comfortable high-frequency syringe use. DCI's Instructions for Use confirm that only silicone-based lubricant using DCI PN 8032 should be used to lubricate Precision Comfort syringe button assemblies and O-rings during reassembly after cleaning, and that other lubricant types may cause O-ring deterioration and syringe malfunction. ? Dental assistants who perform minor syringe maintenance repairs and notice sticking or reduced spring return on a Precision Comfort syringe button find the single PN 3637 button-spring unit provides the targeted component replacement needed for restoring Precision Touch button function without requiring a full repair kit.

Equipment technicians servicing Precision Comfort syringes during dental unit maintenance calls include button-spring replacement as a standard component of the syringe service procedure when button wear or spring fatigue is identified during the inspection. ? DCI International Precision Comfort Syringe Button with Spring gives dental practices a single Precision Touch button-and-spring replacement unit for restoring air or water button function on DCI Precision Comfort syringes, providing the 45% softer Precision Touch activation feel that distinguishes the Precision Comfort platform from standard syringe button designs, for Precision Comfort syringes only, sold individually for targeted single-button replacement, 1 per pack.
