Clamp joint components

•Features and application
The clamp is made of aluminum die cast, and extremely robust to endure repeated use.
Combination of flange, tee, elbow, reducer, bellows, vacuum valve, etc. provides various vacuum exhausting systems easily at customers will.
Clamp joint components are made of SUS 304, and for O-ring material, fluoride rubber and nitrile rubber are available.
Nominal diameters of clamp joint components cover ф10 to ф100, with 7 kinds at maximum.
