• Buna-n nitrile rubber; .799" I.D. x .103" cross-section width
• Different size from DCI 2240; confirm fit before ordering
• For evacuation, delivery, and syringe O-ring replacement
• DCI-manufactured; one of 30 common dental O-ring sizes
• Chemical and fluid resistant; suits dental unit environments
• Quantity: 12 per Pack

DCI International O-Rings, Buna-n, .799" I.D. x .103" Width are used for replacing worn, degraded, or failed O-rings at dental equipment connection points, valve seats, syringe component interfaces, evacuation system connections, and other dental unit sealing locations where an O-ring at the .799 inch inner diameter and .103 inch cross-section width dimension is required to restore the airtight or fluid-tight seal at the equipment connection point during dental unit operation.

O-rings at dental delivery and evacuation system connection points provide the sealing interface that prevents air and fluid leakage at equipment connection joints during clinical use, and worn or cracked O-rings at these locations can result in reduced suction performance, air leakage at delivery system connections, fluid leakage at syringe and handpiece connections, and dental unit performance issues that require O-ring replacement to restore normal equipment function. The .799 inch inner diameter and .103 inch cross-section width of DCI 2297 distinguishes this O-ring from other DCI O-ring sizes including the DCI 2240 Adec style at 2.114 inch inner diameter and .070 inch cross-section, confirming that the correct DCI part number must be verified against the equipment's O-ring seat geometry before ordering to ensure the replacement O-ring matches the dimensional requirements of the specific equipment connection point being serviced. Dental assistants, equipment technicians, and practice managers who maintain dental delivery and evacuation systems and require the DCI 2297 O-ring at .799 inch inner diameter and .103 inch cross-section width find DCI International the Buna-n 12-pack O-ring for their active dental equipment maintenance program. ? Each pack contains 12 individual DCI International O-Rings in Buna-n nitrile rubber at .799 inch inner diameter and .103 inch cross-section width, providing a per-pack O-ring supply for multiple replacement events across the dental unit's service life from a single pack purchase.

The 12-count pack provides a practical quantity of replacement O-rings for a dental practice to stock in their equipment maintenance supplies for planned and unplanned O-ring replacement needs as they arise throughout the year. The DCI 2297 O-ring is one of the 30 most common dental equipment O-ring sizes in the DCI range, confirming its application across commonly serviced dental equipment O-ring positions. ? DCI International O-Rings, .799" I.D. x .103" Width work through their Buna-n nitrile rubber elastomer construction where the O-ring seats within the O-ring groove at the equipment connection point and compresses against the mating sealing surface as the connection is assembled, creating the circumferential seal that prevents air and fluid from bypassing the connection joint during equipment operation under working pressure and vacuum conditions.

Buna-n nitrile rubber provides the chemical resistance, fluid resistance, and compression set resistance needed for O-rings used in dental unit environments where the O-ring is exposed to working pressure and vacuum, evacuated fluids including saliva and blood, handpiece lubricants, and cleaning agents during daily clinical use and maintenance cleaning cycles. Confirming that the .799 inch inner diameter and .103 inch cross-section width match the specific O-ring groove dimensions at the equipment connection point being serviced is essential before installation to ensure proper sealing contact and seal performance. ? Equipment technicians who service dental delivery and evacuation systems during scheduled preventive maintenance appointments and repair calls use DCI O-rings to replace worn or damaged O-rings at the specific connection points identified during the equipment inspection and service procedure. Dental assistants who identify O-ring failure symptoms such as air or fluid leakage at equipment connections during clinical use or during the daily equipment check procedure find the 12-count DCI O-ring pack provides an on-hand replacement supply for immediate O-ring replacement during minor equipment maintenance. ? DCI International O-Rings, Buna-n, .799" I.D.

x .103" Width give dental practices a 12-pack of Buna-n nitrile rubber O-rings at .799 inch inner diameter and .103 inch cross-section width for O-ring replacement at compatible dental delivery, evacuation, and syringe equipment connection points, restoring airtight and fluid-tight sealing performance at worn or failed O-ring positions across dental unit systems.
