ソーワ工業 List of Products and Services

This catalog introduces our gland packing products. It includes "gland packing (white, yellow, black)", "packing for rotating equipment", "packing for valves", and "PTFE-impregnated special aramid fiber packing". Since we weave them with our own braiding machine, we can adjust to the desired dimensions, lengths, and hardness, and it is possible to braid thicker than standard sizes to match the wear condition of the sleeve.
