1. Three-Handed Quick Change (3HQ5) tubes are a type of valve that uses a two-step process for connecting or disconnecting a tube connection. The process begins with a spring-loaded release button, which connects or disconnects the tube using a simple push-pull motion. The second step is an attached quick change valve that instantly seals off the connection with a single twist of the outer knob.
2. 3HQ5 tubes are used in a variety of different applications, such as medical equipment, pneumatics, building and automotive air conditioning systems, and HVAC equipment. They are composed of a combination of stainless steel and plastic, and they are noted for their excellent sealing capabilities and resistance to contamination.
3. While the 3HQ5 tube is not the most common type of valve on the market, it is highly valued for its ease-of-use and its ability to provide a reliable seal on a variety of applications. The tubes also come with a variety of different sizes, styles, and connection types to ensure that they are suitable for any particular application.
