A Type 10 fitting with 1/4" thread nut and stem for the MKIII/MK4 Regulator.
This nut and stem suits Oxygen, Argon, and Helium tanks. The MK4 Regulators comes standard with a Type 30 thread which is suitable only for CO2 cylinders. Remove the existing Type 30 Nut and Stem and replace with the Type 10 to fit to Oxygen, Argon or Helium cylinders. We recommend using a ratchet gun or socket set to do this.
Note: Regulator not included.
