CLINSIL™ Top

TOMBO™ No. 1120

Expanded graphite is its main material, and so it has excellent heat resistance, steam resistance, and corrosion resistance.
It is not susceptible to scratches and has excellent flexibility.
It is used for flanges, valves, and equipment in comparatively hot temperatures.
For low-temperature fluids such as liquefied natural gas (LNG), Nichias recommends TOMBO No.1120-LN, which undergoes special treatment.

CLINSIL™ Brown

TOMBO™ No. 1995

It is a standard grade joint sheet.
Nichias can manufacture large-diameter gaskets without joints at a maximum size of 3810 × 3810 mm (9S size).
It is used for flanges, valves, and equipment in comparatively low temperatures.

CLINSIL™ Super

TOMBO™ No. 1993

It has excellent heat resistance and steam resistance and is suitable for steam lines.

CLINSIL™ Clean

TOMBO™ No. 1133

It can be used for a wide range of fluids such as acids, alkalis, oils, petrochemicals, organic solvents, hot oils, heat-transfer gases, and steam. (Except for some strong alkalis and acids.)
It has the best heat resistance among fluororesin gaskets.
It can also be used for parts that need electrical insulation.

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.

VORTEX™ GASKET

TOMBO™ No. 1839R

It is a gasket with a large amount of filler outside the sealed surface and that enables a seal with less clamping force than regular GRASEAL™ and VORTEX™ gaskets.
It can also be used for low-temperature production lines such as liquefied natural gas (LNG), liquid nitrogen (LN2), and liquefied air.

VORTEX™ GASKET

TOMBO™ No. 1804-GR

It demonstrates excellent sealing performance even in strict conditions such as high temperatures and high pressures, ultra-low temperatures, and thermal cycles.
It offers better sealing performance than NA VORTEX GASKET (particularly sealing against gas).
As it has excellent corrosion resistance, it can be used for corrosive fluids if you choose an appropriate hoop material.
It has excellent sealing performance at low-temperature conditions.
It is a gasket that is particularly suitable for high-temperature and high-pressure steam applications such as pipe flanges, valves, pressure containers, heat exchangers, and valve bonnets of various industries, as well as low-temperature applications like liquefied natural gas (LNG).

VORTEX™ GASKET

TOMBO™ No. 1804-NA

A cost-effective VORTEX GASKET that uses NA paper as a filler.
It is suitable for parts where you want to avoid black filler.
It is used for pipe flanges, pressure containers, heat exchangers, and valve bonnets of various industries.
