GOSHO plug (GM)【1-500 Pieces Per Package】
GOSHO WORKS
[Features]
· The GM type plug is a level seal type (flush type) developed by Gosho. When the plug is screwed into PT (pipe taper) female threading specified in JISB0203, a reference diameter is established near the large end face so that its large end face is almost flush with the mounting face.
· It recently has become the indispensable primary plug for hydraulic and pneumatic equipment.
· It has the advantages of a GM type plug and is a level seal type, so it becomes flush with the embedded and installed main body for a pleasing external appearance and also facilitates miniaturization of machinery
· Comes with a tightening interference, which enables substantial tightening, allowing it to withstand great internal pressure.
· The plug is subject to cold plastic working for high precision, and is heat processed to allow it to be used under high pressure.From: ฿ 18.97 Days to Ship:
