NAFLON™ ML GASKET

TOMBO™ No. 9007-ML

It is a gasket that is suitable for monomer lines.
In a radical polymerization environment, this product displays stable sealing performance over the long term by stopping monomer fluid from seeping into and remaining inside gaskets and causing the “flower blooming phenomenon” where the gasket breaks due to volume expansion.

ENVELOPE 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.

NA MANHOLE GASKET

TOMBO™ No. 1374/13781420-ST/-S/-TH/1400-NA9094

An endless gasket in which woven fabric is coated in a rubber compound and sewn together into various manhole shapes. This gasket has insufficient airtightness, so use it only for parts where some slight leakage is permitted.
It is best suited for applications in which the flange diameter is large, there is distortion, or a high clamping surface pressure will not occur.

PTFE MOLDED PACKING

TOMBO™ No. 9027

A self lip seal type packing that is made by molding PTFE resin into a cross-section VH type, VL type, and D type by machining with a lathe.

Rubber O-ring BLAZER NEXT™

TOMBO™ No. 2670-BNX

BLAZER NEXT is a perfluoroelastomer with excellent heat resistance, radical resistance, purity, and non-stickiness thanks to Nichias’ proprietary cross-linking technologies.
It seals in strict environments where other rubber materials struggle.

BLAZER™ O-ring-S2

TOMBO™ No. 2675-S2

BLAZER S2 is a perfluoroelastomer that shows stable sealing performance in environments with high-temperature steam and nucleophilic agents.
It is a product with significantly improved steam resistance, rapid decompression properties, and crushing properties thanks to Nichias’ newly developed, original cross-linking agent and its proprietary mixing technologies.

BLAZER™ O-ring-A

TOMBO™ No. 2675-A

It has excellent chemical resistance and demonstrates resistance against polar solvents such as amines and chemicals such as organic acids that cannot be used with other fluoroelastomers. It suffers little metal elution and is suitable for applications that require both chemical resistance and purity.

BLAZER™ O-ring-FC

TOMBO™ No. 2675-FC, 2685-FC

BLAZER O-ring-FC (BFC) and BLAZER O-ring-FE (BFE) are made of special fluoroelastomers (special FKM) that are plasma resistant and inexpensive. Thanks to Nichias’ blending technologies, the plasma reduces the weight of the rubber and reduces the occurrence of cracks, and at the same time, it is significantly less expensive than perfluoroelastomer (FFKM).

BLAZER™ O-ring-FE

TOMBO™ No. 2675-FE, 2685-FE

BLAZER O-ring-FC (BFC) and BLAZER O-ring-FE (BFE) are made of special fluoroelastomers (special FKM) that are plasma resistant and inexpensive. Thanks to Nichias’ blending technologies, the plasma reduces the weight of the rubber and reduces the occurrence of cracks, and at the same time, it is significantly less expensive than perfluoroelastomer (FFKM).

Rubber O-ring Perfluoro PFW

TOMBO™ No. 2670-PFW

It has excellent plasma resistance and is used in dry etching equipment to manufacture semiconductors.

Rubber O-ring Fluoro-Plus

TOMBO™ No. 2670-FA-F

Fluoro-Plus is a special fluoroelastomer that maintains the chemical resistance and heat resistance of a regular fluoroelastomer but has significantly improved wear resistance and non-stickiness.
Fluoro-Plus is different from outer membrane coatings and is a product that undergoes treatment by way of a surface improvement method. As a result, it maintains its attributes over the long term and it experiences no peeling of the surface layer.

Rubber O-ring Fluoroelastomer FB

TOMBO™ No. 2670-FB

Fluoroelastomer FB is a ternary fluoroelastomer with improved chemical resistance due to Nichias’ proprietary compounding technologies. It has excellent resistance against high-temperature acids and steam for which a general-use fluoroelastomer cannot be used. There is very little metal elution and it has excellent purity. A high-performance fluoroelastomer that is excellent value for money.
