Cloth gasket
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.
Cloth gasket
NA MANHOLE GASKET
TOMBO™ No. 1374
A gasket in which a glass fiber cloth 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.
Cloth gasket
NA TADPOLE GASKET
TOMBO™ No. 1378
TOMBO No.1368 is a gasket that is machined into a ring shape and is suitable for the doors of furnaces, heaters, and dryers, as well as dampers and exhaust gas, hot air, and dust manholes.
Cloth gasket
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.
Cloth gasket
NAFLON™ MANHOLE GASKET
TOMBO™ No. 9094
It is a manhole gasket made by using PTFE dispersion for the joint material.
It is used for ducts that require chemical resistance and solvent resistance and corrosive gases such as acidic exhaust gas.
Valve packing
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.
Valve packing
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.
LOW TORQUE ADAPTER PACKING
LOW TORQUE ADAPTER PACKING
TOMBO™ No. 2250
By using it in combination with TOMBO No.2205_P, you can expect sealing performance and a significant reduction in sliding friction equivalent to that of the conventional GRASEAL PACKING combination (TOMBO No.2205_L + TOMBO No.2930, etc.).
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 various fluids (However, it cannot be used for oxidizing acids, oxidizing salts, halogen compounds, and combustion-supporting gases because they oxidize away the expanded graphite.)
It has little stress relaxation, and so demonstrates stable sealing performance over the long term.
Valve packing
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.
