For every piece of dive gear, there seems to be an o-ring. The Blue Steel SCUBA Tank O-Ring is no different. So ensure you have all the air you can hold with the Blue Steel SCUBA Tank O-Ring. Using the proper size tool, pull out the insert, and check the Inner O Ring, making sure it still has its shape, and no cracks. It's just like checking the o-ring before you connect your first stage to the tank. For any questions regarding the Blue Steel SCUBA Tank O-Ring, contact a professional at Divers Direct.
