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.

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.

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.
