Instant attachment and detachment with air drive! Achieves labor-saving and reliable sealing with outer circumference locking, operating with factory air instead of lever operation.
The One-Touch Seal Coupler "EX Series" is a sealing fixture that employs an air-driven outer circumference locking mechanism, strongly supporting the automation and efficiency of work processes. It eliminates the manual operation of traditional lever-type couplers and automates the attachment and detachment actions using factory air. This significantly contributes to reducing operational errors and alleviating the workload. This product is available in various types, including outer circumference lock, inner circumference lock, and inner and outer circumference lock, allowing for optimal selection based on the shape and material of the workpiece to be connected. It is particularly suitable for handling soft materials such as resin pipes and rubber hoses, as well as large diameter sizes that are difficult to manage manually. It is compatible with a wide range of applications, including cooling piping in the automotive industry, around compressors in air conditioning equipment, and tank systems in industrial machinery, and is utilized in various processes such as leak testing, pressure testing, and airtight testing. Furthermore, it allows for easy and quick attachment and detachment without the need for processing the end face or outer circumference of the workpiece, significantly improving work efficiency on the manufacturing line. Custom solutions are also available upon request through dedicated design. *For more details, please download the PDF or feel free to contact us.*
