Bellows Seal for Process Chemical
Superb corrosion resistance makes this seal applicable to any chemical liquids.
This product ensures ideal corrosion resistance. PTFE is used for all the rotating parts that come into contact with liquids. Carbon and PTFE containing fillers are used for the sliding materials.
Corrosion-resistant metallic materials are used for parts that do not come into direct contact with fluids. This product can handle any chemical liquids including reducing agents, strong acid/alkaline liquids, salts, and concentrated acids.
PTFE bellows type seal for low pressures (used as an outside seal)
* The Y8K is an outside seal and does not meet ISO standards.
A quenching device is required for the flange.
