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.
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.
TOMBO™ No. 1993
It has excellent heat resistance and steam resistance and is suitable for steam lines.
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.
Special filler filled PTFE cut gasket (low creep)
NAFLON™ LC GASKET
TOMBO™ No. 9007-LC
NAFLON LC GASKET has excellent chemical resistance and anti-staining properties, and is used as a gasket material in a wide range of industries such as fine chemicals, petrochemical industry, pharmaceuticals, food industry, and semiconductor industry.
Rolled PTFE gasket
TOMBO™ No. 9096-SGM
SGM Gasket is a PTFE soft type gasket made of high-strength expanded PTFE.
As it is soft and has excellent adaptability, it can easily seal slightly uneven surfaces.
It can be used for almost all fluids that do not corrode PTFE.
It can also be used as an electrical insulation gasket.
PTFE enveloped gasket
TOMBO™ No. 9010series
A PTFE-wrapped gasket that is made by covering the core material such as a joint sheet with a PTFE outer skin.
The sealed surface is completely covered in a PTFE membrane. It has excellent anti-staining properties and chemical resistance, and therefore it is used for a broad range of applications including fine chemicals, petrochemicals, the pharmaceutical and food industry, and general manufacturing.
Spiral wound gasket with expanded graphite filler
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).
Spiral wound gasket with NA paper filler
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.
Spiral wound gasket made of fluororesin filler
TOMBO™ No. 9090
Because it uses PTFE with excellent chemical resistance as a filler, it can be used for almost all fluids if you choose an appropriate hoop material.
It is one of the best VORTEX gaskets in terms of sealing performance, and it can also be used for vacuum applications.
It is used for pipe flanges, pressure containers, heat exchanges, and valve bonnets from various industries. It is suitable for sealing against corrosive fluids and oxygen that other VORTEX products cannot be used for, parts that especially require airtightness, and vacuum sealing.
For applications using pure liquid oxygen, Nichias also offers an OX type that removes PTFE oil components.
SUPER MANHOLE GASKET
TOMBO™ No. 1420-TH
It is a gasket in which woven fabric is coated in a rubber compound and sewn together into a manhole shape.
NA MANHOLE GASKET
TOMBO™ No. 1374
A gasket in which a glass fiber cloth is coated in a rubber compound and sewn together into a manhole shape.
This product is suitable for exhaust gas and hot air manholes, handholes, autoclaves, large-diameter flanges, diesel engine exhaust pipes, flue manholes, and boiler combustion openings.
