World's smallest push-button non-spill coupling (joint connector) NS1 Compatible with diameters from 3.2 mm to micro tubes The NS1 series coupling is a non-spill type that prevents liquid dripping when disconnected. The air intrusion into the flow path is also extremely minimal. The NS1 is the smallest non-spill coupling, accommodating sizes from 3.2 mm to micro tubes. It features a rotation function that alleviates tube twisting. It is ideal for applications that require repeated connections and disconnections. Not only is it simple and easy to use, but it also allows for safe and reliable connections.

Closed system for overseas drums A closed system for high-purity chemicals such as chemicals for semiconductors and resists. It minimizes contact with the outside air. This joint system greatly enhances safety when filling and selling chemicals in drums or containers, or when processing waste liquids. It allows drums and containers to be closed (sealed) instantly without liquid spillage, thereby minimizing chemical exposure for workers transporting liquids from drums or containers and preventing contamination of the surrounding environment.

Motorcycle gasoline connector (joint, connector, coupling) Widely used in BMW (mass production) and domestic racing model motorcycles, with a long track record. It has valves on both sides, stopping the gasoline flow. It can be attached and detached under pressure. Maintenance becomes very quick. During maintenance, it prevents gasoline splatter, ensuring safety. If it accidentally disconnects due to improper operation, it is safe because of the valves. It prevents dirt and water from entering the engine line during maintenance. Plastic and metal options are available. Plastic is inexpensive, lightweight, and compact.

Blood circuit transfusion connector (joint, connector, coupling) There are numerous approval records in the US and Europe. It is made from plastics confirmed for safety, such as USP Class VI, and is economically priced even for single-use. The one-touch button allows for easy attachment and detachment with one hand while wearing gloves. It also prevents incorrect connections with luer locks. A clicking sound indicates a secure connection when attached. It is manufactured in a clean room.
