Anti-retraction (non-suck-back) valve: Helps prevent contaminated fluids from being drawn back into the supply hose, improving infection control.
Stainless‐steel body with titanium coating: Offers durability, corrosion resistance, and repeated sterilisation capacity.
Designed for the NSK “PTL” quick-coupling system (often for 6-pin/fibre‐optic handpieces) so compatibility with modern high-speed handpieces is facilitated.
Autoclavable / sterilisation‐friendly: The coupling system supports sterilisation (including 135 °C in some models) as part of NSK’s high-speed turbine/handpiece ecosystem.
Quick‐fit / release mechanism: The manual for PTL couplers shows the process for connection/disconnection (pull back retaining ring etc), meaning that the coupling is designed for easy handpiece changeover.
