After installation, you can change the take-off angle of the resin body.
Allows centralized piping.
The triple types (PKD, PKG, PKJ) and twin triple types (PKVD, PKVG) enable compact, centralized piping.
We offer a clean washing specification suitable for various particle- and oil-averse production processes. (Optional setting for clean room packaging specification) The product is vacuum sealed after ultrasonic vacuum cleaning with HFE (hydrofluoroether) in a clean room.
The lock claw evenly grips the circumference of the tube. Even after many years, tubes still attach and detach like new.
Unique elastic sleeve design shuts out air leaks.
Industry-leading range of variations
A wide assortment of different-diameter sizes is available. One fitting can be used where traditionally two fittings were required.
By reducing the number of fittings used, you can reduce costs and space.
We offer a clean room packaging specification, which is suited to piping in a clean environment. (option)
The product uses fluorochemical grease and is cleaned with clean air before being packaged in a clean room (equivalent to ISO Class 6).
The seal part uses a unique elastic sleeve that shuts out air leaks.
When release ring has been pushed
Push the release ring to collapse and hide the lock claw.
Normal state
The lock claw evenly grips the circumference of the tube. Removal and refitting feels almost the same as the first insertion.
When you release your finger from the release ring, the fine ridges of the lock claw come into view.
