Series 19 Leader Hose 3/8" x 3/8" - LH19/17K ‘Leader Hose' is a length of flexible hose which should be fitted between an air tool & the connecting coupling. By absorbing the impact of a pneumatic impact tool, a leader hose will significantly increase the life expectancy of the coupling. • WARNING • – Leader Hoses The Health & Safety Executive guide states - "the plug should not be screwed directly into the inlet port, but should be fitted onto a short isolation hose, thus isolating the plug & coupling from the tool vibration" .
