Nitrox Tank Inspection O-rings

Tired of paying high prices for Scuba Tank Neck O-rings?  I was too, so went out and found a reliable source for genuine DuPont Viton® O-rings.  Each of the o-rings listed below is made from virgin material and has been tested by an independent engineering laboratory to verify that they are the correct hardness.  These o-rings have been tested to meet the ASTM specification for 90 durometers of hardness on the "A" scale, which is correct for the static o-rings used on scuba tanks.

Viton o-rings are typically used for Nitrox tanks or Oxygen Service.
