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.Standard Price: MYR 2.47- Days to Ship: 5 Day(s) or more -

[Features]
·Material: Structural carbon steel.
·Hardness: HRC32 to 42.
·Since it is a level seal type, it is flush with the main body that is embedded and installed, making it possible to make the device smaller and smarter in appearance.
·Since the screws are NPTF, excellent strength and tightness can be obtained without using a sealant.
·The taper of the plug is 1/13.714 (7/8" per 1ft), so it bites into the NPTF female thread with a pick and provides excellent tightening.Standard Price: MYR 4.04- Days to Ship: 5 Day(s) or more
