METAL O-SEAL

TOMBO™ No. 9200P

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.
It is used by fitting it onto the grooves and fully clamping it to enable a high-pressure seal with little clamping force.
If the internal pressure is 7 MPa or more, please use TOMBO No.9200V (model with holes).
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.

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.

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.

SUPER MANHOLE GASKET

TOMBO™ No. 1400-NA

It is a gasket in which woven fabric 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.

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.

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.

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.
