• others

Two types of screws are available for the mounting part: pipe taper screws and metric screws!

• Sealing

The flange for mounting on the machine shaft or device is integrated with the body!

• Sealing

It is possible to supply fluid through two independent passages from the end of the shaft!

• Sealing

The outer circumference of the mounting flange has been machined with Rc1/2 threads, allowing it to be used as an external passage as well!

• Sealing

Since it is a flange type for mounting, installation on the shaft end is easy! All four passages can supply fluid directly into the rotating shaft.

• Sealing

All screws for the mounting part are metric fine thread! Introducing the OS type for medium pressure.

• Sealing

All screws for the mounting part are fine metric screws! Introducing the HOS type for high pressure.

• Sealing

Also usable as an oil circulation system! Can be used for different purposes.

• valve
• Sealing

All screws in the mounting section are pipe taper screws! Rotor seal for supplying one type of fluid to the rotating body.

• valve
• Sealing

It can also be used as a circulation cooling system for devices mounted on the rotating axis!

• valve
• Sealing

The V-ring seal, which excels in dust sealing effects at low torque and is easy to install retroactively, is offered at a reasonable price.

• Sealing

Introducing our achievements in valve flanges (wire/clamp method) and valves (box method)!

• Sealing

Developed for sealing applications in harsh environments where excellent chemical resistance is required!

• Sealing

It is suitable for use under harsh conditions such as high humidity, chemical plants, and high-speed rotation!

• Sealing

Use a backup ring to prevent overflow from gaps under high pressure!

• Sealing
