Tapered Thread Plug With Hex Socket Head, GJ Type

GOSHO WORKS

Taper plug usable in high pressure (high airtightness) conditions developed for reliability.

[Features]
· The GJ type plug is referred to as a "float type" (JIS type), so when it is screwed into the PT or PS female thread specified in JISB0203, the standard diameter of the taper thread is established near the center of the length (I) so that the large end service is higher than the mounting surface.
· Conventionally, a PT plug with a square hole is specified by JIS in place of a hex hole for the GJ type, but recently in order to improve the safety and work efficiency of tightening, hex socket head GJ plugs capable of reliable tightening have come to be used in various quarters.
