It was an inconvenience to connect the air hose to the straight shape plug which is standard equipped with a heavy 25.4 mm impact on the floor. Easy to connect if you change this rotary plug! The hose does not get in the way because the connection moves during work! It is a gem that I recommend by all means.
It purchases to use for 1/4 and 3/8 impact wrench used for motorcycles and cars with Sunday mechanic, it is a serious plug without torsion or entanglement of hose after installation. There was a case that air leaked from the part where just two purchased and one got rounded. I am giving up as if there is no choice when thinking of COSPA. However, we are pleased that the product was very convenient and the price was cheaply available. I think that it is good to reorder at the time of free shipping together with other goods because it is a waste to purchase separately and bear the postage.
Although it is used for the impact wrench which is used most frequently among air tools, since the coupler part rotates freely freely, freedom is helpfuled in handling the hose. If the price is a little cheaper then I would like to equip it with other air tools.
