METAL O-SEAL

TOMBO™ No. 9200V

A gasket made by molding thin metal piping into the shape of an O-ring, welding it at the ends, and then subjecting the surface to ultra-precision finishing. This gasket provides a very reliable, top-class seal across a wide range of conditions from high temperatures to low temperatures and high pressure to vacuum states.
TOMBO No.9200V has two or more small holes on the inside (for internal pressure) of the ring or outside (for outside pressure) and demonstrates top-class sealing even at high pressure due to fluid entering the inside of the ring and causing autofrettage to take place.
In the case of gaseous fluids, vacuumed fluids, and highly volatile fluids, Nichias recommends its PTFE coating or silver plating specifications.
It is used for various applications such as valve bonnets, high-pressure container flanges, equipment joints, pipe flanges, plastic processing machinery, rubber extruders, hydraulic equipment, air pressure equipment, vacuum equipment, nuclear vessels, aircraft engines, rocket engines, and automobile engines.

GRASEAL™ PACKING

TOMBO™ No. 2200

By using it in combination with adapter packing such as TOMBO No.2250-A, it delivers outstanding sealing performance.
The drop in performance from ultra-low temperatures to high temperatures is minimal.
Expanded graphite (GRASEAL) has chemical resistance second only to PTFE and can be used for almost any fluid, except for the prohibited fluids below.
It has little stress relaxation and so it demonstrates stable sealing performance over the long term.

GRASEAL™ PACKING M

TOMBO™ No. 2205

By using it in combination with adapter packing such as TOMBO No.2250, it delivers outstanding sealing performance.
The drop in performance from ultra-low temperatures to high temperatures is minimal.
Expanded graphite (GRASEAL) has chemical resistance second only to PTFE and can be used for almost any fluid, except for the prohibited fluids below.
It has little stress relaxation and so it demonstrates stable sealing performance over the long term.

SUPER SEAL PACKING

TOMBO™ No. 2280-S

It has fantastic sealing performance in comparison to fiber-braided packing.
Expanded graphite has chemical resistance second only to PTFE and can be used for various fluids (However, it cannot be used for oxidizing acids, oxidizing salts, halogen compounds, and combustion-supporting gases.)
It can be used on its own without using an adapter packing.
A string-like packing has a rectangular cross-section so that it can be easily installed into a stuffing box.
It is treated with Nichias’ proprietary anti-corrosive agent, and so demonstrates excellent anti-corrosive performance and can also be used well with valve rods made of 13 chrome steel.
It can be stored in a string-like form and so it can be used to address problems immediately in an emergency.

RF BOARD™

TOMBO™ No. 5461

RF BOARD is a product made by adding inorganic and organic binders to alumina fiber and then molding this into a board form.
As it is made of a fiber-based board, it has little heat storage volume. It can be used to design compact furnaces thanks to its excellent thermal insulation properties and workability.
Nichias has a lineup of various dense boards that are suitable for working temperatures of 1, 400°C to 1, 800°C or parts used in such an environment.
Therefore, it performs really well as a lining material for ultra-high-temperature electric furnaces and various high-temperature furnaces.

MARINETEX

TOMBO™ No. 8200

MARINETEX is a lagging cloth and tape for thermal insulation applications, made by weaving ultra-fine glass fiber with bulky yarn and subjecting it to repeated special treatment to eliminate the prickling sensation of the glass.
It provides excellent thermal insulation and is flexible and stretchy, making it suitable for bonding and sewing. It can be easily installed even in the most complicated of places.

INSULTEX

TOMBO™ No. 8400/8401/8402/8403

Thick glass cloth, tape and yarn for thermal insulation, made by weaving bulky, treated glass yarn. A special heat treatment is applied to the product, and thus it has high strength and maintains its flexibility even at high temperatures unlike conventional glass cloth.
It is suitable for applications that require a cloth that is thicker than our TOMBO No. 8200 MARINETEX.

ALUMINIZED CLOTH

TOMBO™ No. 8982

It is a product that is made by welding aluminum foil onto MARINETEX Cloth or INSULTEX Cloth or bonding an aluminum metallized film to the cloth.

Silica Textile

TOMBO™ No. 8250

This is a silica cloth developed for severe conditions in high temperature ranges for which glass cloth is not compatible. Due to the high purity of the SiO2 fiber, there is little deterioration in the silica cloth even when used at high temperatures, making it particularly suitable for applications requiring heat resistance, acid resistance, and electrical insulation.

FIRE PROOF CLOTH

TOMBO™ No. 8300

Shipyards and construction sites are constantly exposed to the risk of fires due to spatter and slag produced during welding and cutting. There may also be cases where vital equipment such as computers could be damaged. Our Fire-Proof Cloth is a dedicated spark-protection cloth developed to withstand such severe conditions.

ENETHERMO™ R

TOMBO™ No. 4500-R

It is an attachable thermal insulation material that can be used repeatedly.
Nichias assists in environmental conservation and improvements through energy saving initiatives at buildings and plants.
