Concoa Precision Gas Controls
Concoa is the market leader in the USA, with a large number of different regulators, switchover panels and other types of gas blending products.
Concoa has been using Hy-Lok accessories for its panels for many years, and this has made a broader cooperation natural. If the surface smoothness is insufficient or if aggressive media are used, it is possible to obtain regulators with a Dursan treatment.
Dursan is a "glaze" that provides an extremely smooth surface. This may be appropriate when you want to get very accurate measurements on the gas or work with aggressive gases where materials like monel or hasteloy may typically be used.
Dursan is many times stronger than these materials and therefore should not need to be repaired or replaced with the traditional frequency, if ever!
