DCI 5684 Precision Comfort HVE Q.D. Swivel – 28 mm Swivel to 22 mm Barb Adapter

[AcmeDent sku="PE3556"]

Equip your dental evacuation system with the dependable DCI 5684 Precision Comfort HVE Q.D. (Quick Disconnect) Swivel, engineered for high-performance suction and optimal compatibility in clinical environments. This precision component features a 28 mm swivel coupling and a 22 mm barb connection for downstream tubing — ideal for connecting high-volume evacuation (HVE) lines with minimal turbulence and improved hose mobility.

Crafted for dental professionals, the swivel mechanism allows free rotation of the hose line, reducing kinks and strain on connections in operatory settings. A built-in O-ring seal ensures reliable vacuum integrity and helps maintain negative pressure during moist or debris-laden suctioning tasks. This part is particularly valuable when retrofitting or maintaining systems originally designed for brands such as A-dec® or DÜRR®, ensuring seamless integration with existing chairside tubing and holders.

Key Features & Benefits:

• 28 mm swivel coupling with 22 mm barb — standard fit for many HVE tubing systems.
• Quick-disconnect design allows fast installation or maintenance of the HVE line.
• Durable O-ring seal for sustained vacuum performance and reduced leakage.
• Improves hose manoeuvrability and operatory ergonomics, minimizing drag on suction tubing.
• Ideal for routine maintenance or upgrades of dental evacuation systems to maintain optimal suction for saliva, aerosols and patient comfort.
• Compatible with holders and tubing from multiple manufacturers, making it a versatile replacement part.

Suggested Use: Replace worn or inefficient swivel couplings in the high-volume evacuation arm of your dental unit. Regular maintenance of the swivel can help preserve suction strength, reduce noise or vibration in the tubing network, and enhance the overall clinical workflow.
