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.

LOW TORQUE ADAPTER PACKING
![](/cms/nichias/img/products/item/seal/packings/571724c9b9520.jpg)
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.

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.

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.
