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.
