NICHIAS SOFT SEAL

TOMBO™ No. 9096

It is a soft gasket made of PTFE.
It is extremely soft, and the model with adhesive tape can easily be installed on sealed surfaces of complex shapes.
It is used for the likes of pipe sealant, tanks, casing, pressure containers, stress tanks, lining equipment, and large-diameter equipment.

GRASEAL™ GASKET

TOMBO™ No. 1200

It is more cost-effective than the other GRASEAL GASKET models.
As it is weaker and less workable than the steel sheet type, Nichias recommends using it only for nominal diameters of 4 inches or less.
It can be used for uniquely shaped flanges such as liquid level gauges, as well as various industrial pipe flanges, heat exchanges, and valve bonnets.

GRASEAL™ GASKET MI-A

TOMBO™ No. 1210-A

It is stronger than TOMBO No.1215-A due to its pronged steel plate.
Nichias recommends this product if TOMBO No.1215-A is not strong enough for you or if there are specification restrictions.

GRASEAL™ GASKET PM

TOMBO™ No. 1215

It has excellent workability and can be machined into complex shapes.
It is used for uniquely shaped flanges, valve bonnets, heat exchangers, etc.
Nichias also offers TOMBO No.1215-T, which has improved sealing performance against gas by undergoing treatment to make it impervious. (However, its maximum working temperature is 260°C.)

GRASEAL™ GASKET PM-A

TOMBO™ No. 1215-A

It has excellent workability and can be machined into complex shapes.
It is used for uniquely shaped flanges, valve bonnets, heat exchangers, etc.

CMGC GASKET

TOMBO™ No. 1880-GR

It is a gasket that, by adopting a corrugated design, concentrates the surface pressure and improves the sealing performance.
It can also be machined into unique shapes such as frames and flat faces.
It is used for uniquely shaped flanges, valve bonnets, and heat exchangers, and has also been used at many overseas oil companies.
The performance hardly drops from low temperatures to high temperatures (400°C).
It can be used for almost all fluids, except for strong oxidizing acids.
