The SmartQIC coupling is a one-hand operation coupling with high air flow performance. It is suitable for many types of applications and pneumatic tools; such as screwdrivers, assembly tools, drills and grinders. The coupling is strong and durable and is made of zinc-plated steel/brass. Designed with a unique safety venting feature the couplings vent the air before it is able to fully disconnect, thus minimizing risk of damage to the operator.
