トルクレンチの精度管理
トルクレンチは計測器ではありませんが、ねじ締めトルクを一定にするため設定値（トルク値）の管理をする。
これは毎月実際のトルク値をトルクテスターによって測定し、基準値内（設定値の±７％）にあることを確認する。
ホース管体にアルミパイプを挿入し、円筒状のスリーブをかしめて結合される。
カーエアコンのコンプレッサやコンデンサなどの各機能部品を連結する冷媒の通路であり、ホースは車の振動を吸収し、機能部品を保護する役目も担う。

Accuracy control of the torque wrench
The torque wrench is not a measuring instrument, but the set value (torque value) is controlled to maintain the screw tightening torque constant.
It is to verify that the actual torque is within the standard value (within +/- 7% of the set value) by the torque tester every month.
It is combined by swaging the cylindrical sleeve after inserting an aluminum pipe into the hose tube.
It is a pathway of refrigerant which combines each functional part of the compressor and the condenser etc. of the car air-conditioner and the hose absorbs vibration of the car and also acts to protect each functional part as well.
Quality defects to be expected
Difference of bending angle of the pipe

Accuracy management of a torgue wrench.
A torgue wrench is not a measuring instrument, but manages with the setting value (torgue value) to stabilize a setscrew torgue.
In other words, the torgue value is checked by a torgue tester every month, and confirmed if it is within a reference ( +/- 7% of the setting value.)
Combined by inserting an aluminum pipe into a hosepipe as well as caulking with a cylindrical sleeve.
It is a cooling path connecting each functional part of a compressor, a condenser and as such for the car air conditioner. Also, the hose is responsible for absorbing vibrations from the car and protecting the functional parts.
The possible defect of the quality
Wrong bending angle of the pipe.
