The HEXA PLUG is used to shut & open at end of pipes during pipe works for preventing contaminate of foreign materials into pipe, such as liquids, gases and solid object.

Sapotex" is a pipe end sealing device that effectively utilizes the elasticity of rubber to solve various problems such as electric conduction and rust caused by contact between main and sheath pipes in double plumbing, as well as earth and sand flowing into the gap between main and sheath pipes.

This is a double-pipe sealing device that prevents the inflow of earth and sand from flowing through the gap between the main and sheath pipes in double piping and also prevents electrical corrosion caused by contact between the main and sheath pipes.

It is composite products of synthetic rubber and chemical fiber,
which have been used by Japanese domestic gas meter manufacturers since the 1960s.Also, the products have been adopted by major international gas meter manufacturers who are in Europe, the Middle East and Asia and had a good reputation in terms of the assured accuracy and durability required of measuring diaphrams for gas meters.

This, one of the most important part of the gas meters, is made in thermosetting material. The dimensions of these parts have to remain constant over time despite temperature or humidity of the gas. In addition, the part is rarely be affected by the impurities such as water, zinc, brick rubbish which are sometimes in the gas.
It has been used for various volume of gas meters.
