High precision with cold forming processing! A plug with a level seal type that also enables miniaturization of machines.
The "GM type plug" is a product designed so that when the plug is screwed into a PT thread defined by JIS B 0203 (pipe tapered thread), the large end face is nearly on the same plane as the mounting surface, with the reference diameter set close to the large end face. The plug is made using cold working, which ensures high precision, and it is heat-treated, allowing it to be used under high pressure. As a level seal type, it is flush with the embedded main body when installed, providing a smart appearance and enabling miniaturization of the machinery. In addition, we also handle the floating type "GJ type plug." 【Features】 ■ Level seal type (flush type) ■ Enables miniaturization of machinery ■ Includes tightening allowance ■ High precision due to cold working ■ Usable under high pressure *For more details, please refer to the PDF document or feel free to contact us.
