It is usually made of carbon steel with nickel-plated on the surface or brass with acid pickling, and the internal element is made of brass as well. This series of quick couplings are designed with 4 steel balls, and its maximum working pressure is between IH20 and IM20 series.
If replace its sealing with FKM, it can also work under high temperature conditions. The regular IK20 is designed with a 1/4" flow rate body. If needs a larger flow rate, you are recommended to choose IN30, IN40 series.
