I currently have an Odyssesy Torrid and I blew the o-ring around the hammer. This o-ring is not a regular o-ring. It is kinda hard to explain what it looks like but its not an orginary o-ring that you can get from the store. I call odyssey to see if they have any of this type of o-ring but the guy told me that they didnt have any in and he didnt know when they where getting more in. SO if anyone has any information on where to get special types of o-rings or know what type of o-ring i am talking about it would be helpful.
Find out the dimensions on it. O-rings have specs. Then you can call different supply houses and see if you can find one. Check Ace hardware and other places.
