Due to the heavy typhoon attacked to Japan on Sep/4/2018,
Items will be shipped from Narita International Airport(NRT) or Chubu Centrair International Airport(NGO),
which normally should have been shipped from Kansai International Airport(KIX).
It may cause delay on shipment. Sorry to have kept you waiting and thank you very much for your understandings.
I used to remove the ring because the socket attaching / detaching is hard from the time of purchasing a new article of Ingasoll's impact. I was looking for something inconvenient for the socket to fall. Fit perfectly when you bought this product and trying O-ring. It is very satisfying because it seems that desorption of the socket can be done smoothly.
I bought it because the old NPK Impact Wrench socket will fall out. Because it looked thinner than what was attached from the original appearance, though I thought that it failed, I could exchange it without problems. I am satisfied as I got to secure the socket firmly.
