Spiral wound gasket with expanded graphite filler

VORTEX™ GASKET

TOMBO™ No. 1804-GR

It demonstrates excellent sealing performance even in strict conditions such as high temperatures and high pressures, ultra-low temperatures, and thermal cycles.
It offers better sealing performance than NA VORTEX GASKET (particularly sealing against gas).
As it has excellent corrosion resistance, it can be used for corrosive fluids if you choose an appropriate hoop material.
It has excellent sealing performance at low-temperature conditions.
It is a gasket that is particularly suitable for high-temperature and high-pressure steam applications such as pipe flanges, valves, pressure containers, heat exchangers, and valve bonnets of various industries, as well as low-temperature applications like liquefied natural gas (LNG).

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.

Valve packing

ALMETAL PACKING

TOMBO™ No. 2788-AF

It is a metallic packing with a particularly high level of flexibility and elasticity as well as superior heat dissipation properties.
Please use it together with TOMBO No.2200 (or TOMBO No.2205-P, etc.).

Valve packing

GRAPHITE FIBER PACKING

TOMBO™ No. 2940(バルブ用)

It is a packing with excellent heat resistance and chemical resistance.
It can be used for almost all fluids, except for strong oxidizing acids.

Valve packing

PLASTIC GRAPHITE PKG

TOMBO™ No. 2996-NA

It has excellent flexibility, and so it adapts well to valve rods and has outstanding sealing properties.
A packing for exclusive use with bronze and cast iron valves for water, hot water, low-pressure steam, oil, and gas.

Packings for rotating equipment

NAFLON™ FIBER PACKING-G

TOMBO™ No. 9042-S(回転機器用)

It is easy to cut, and as the cut opening is unlikely to fray, it is easy to handle.
The PTFE base material achieves outstandingly low sliding.

Valve packing

NAFLON™ FIBER PACKING-T

TOMBO™ No. 9033(バルブ用)

PTFE has extremely good chemical resistance and can be used for almost all fluids from strong acids to strong alkalis.
It is made of PTFE, and so there is no melting or extraction from solvents or fine chemicals.
The self-lubricating properties of PTFE can reduce the torque of valve rods.

Valve packing

NAFLON™ FIBER PACKING-T

TOMBO™ No. 9034(バルブ用)

PTFE has extremely good chemical resistance and can be used for almost all fluids from strong acids to strong alkalis.
The self-lubricating properties of PTFE can reduce the torque of valve rods.
