Packings for rotating equipment


TOMBO™ No. 9077-L

It offers excellent heat resistance. <br>
Carbon fibers have excellent chemical resistance and can be used for almost all fluids except for strong oxidizing acids.

Self lip-seal type PTFE 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.

Rotary Shaft Packing

Oxidized PAN fiber Packing (for rotary shaft)

TOMBO™ No. 9039

Good seal performance under high revolutions.
Less shaft and sleeve abrasion than asbestos packing.
Economical among packing.

Heat and chemical-resistant perfluoro elastomer

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.

Steam-resistant perfluoro elastomer

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.

Chemical-resistant perfluoro elastomer

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.

Low-friction, non-cohesive fluoro elastomer

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.

Chemical-resistant fluoro elastomer

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.

Rubber O-ring

Rubber O-ring

TOMBO™ No. 2670

A self-seal type rubber O-ring that is made by putting various rubber elastomers into a mold and machining both ends together into a circular shape.
In addition to a shaft seal (packing), it is also fitted into grooves and used as a gasket. It adapts well even with a small clamping load, and can seal against a vacuum pressure up to a high pressure of 25 MPa.

Rubber molded gasket (PTFE-cladded)


TOMBO™ No. 9013/9013-D

A gasket that is made with rubber as its core material and molding a PTFE film before applying pressure and heat to bond them together. It is a gasket with excellent sealing performance that combines the elasticity of rubber with the corrosion resistance of PTFE. EBILON GASKET is best suited for the applications of parts that are not subject to much clamping force such as PVC pipes and glass-lined pipes.

Rubber molded gasket (solid rubber product)


TOMBO™ No. 9013-EP/DEP

A gasket made by pressure molding a single piece of rubber into a cross-section shape that offers an even lower surface pressure and stable sealing performance than a rubber seat gasket. Nichias recommends using this product for parts with mild usage conditions and that do not require much chemical resistance.

Rubber cut gasket


TOMBO™ No. 1050/1051

A low-pressure-use gasket that can seal at the lowest possible surface pressure thanks to the elasticity, recoverability, and adaptability of the rubber. TOMBO No.1051 is reinforced with polyester fabric and so there is less flange protrusion. It is, however, inappropriate to use TOMBO No.1051 when sealing against gas.
