Description
This part is a small, precision seal critical for the internal function of a high-speed dental handpiece turbine or the coupler that attaches the handpiece to the tubing. The term "Quad" indicates its unique cross-section shape.
Key Features and Function
-
Function
-
The seal is essential for separating and maintaining pressure in the air and water channels of the handpiece.
-
It prevents air and water leakage, which is critical for the handpiece to achieve its full speed (RPM) and deliver a consistent water spray for cooling.
-
Compatibility
-
Designed to fit various Midwest handpiece models, including those with 4-hole or 5-hole connections, such as the Quiet Air, Tradition, and XGT lines.
-
Material
-
Typically made from highly durable, autoclavable materials like Viton or Fluorosilicone to withstand high heat sterilization and exposure to cleaning solvents and oil.
-
Maintenance
-
Regular replacement of these O-rings is a key part of preventative maintenance for dental handpieces to ensure longevity and optimal performance.
