XS Scuba PVD Pro Valve X-Series Steel Cylinder

  XS Scuba's Physical Vapor Deposition (PVD) Finish Pro Valve has the same type of long lasting finish you find on expensive faucets, high-end door lock sets and premium watches. PVD is not only a beautiful finish, but is also extremely durable. Before assembly the finished marine grade brass with triple bright chrome plating parts receive the PVD finish process. The parts are placed in a vacuum chamber, where a high power electric arc is discharged at the source material blasting away some into a highly ionized vapor which is deposited on the parts. XS Scuba's black colored PVD finish is accomplished with the use of Titanium Nitride. It provides the following advantages: Significantly harder exterior finish of 250 HV, a coating thickness of 0.2 to 0.3 micrometers, incredible resistance to salt water corrosion, increased scratch resistance and a very cool tech look.Precision machined from high tension brass and chrome plated the valve stems will give years of service and corrosion fr
