FLATFACE HONA QPQ – QF

Series Q flat face couplings are innovative product which finds ideal application in medium corrosive environmental conditions. The Q series is a special version of F serie where the carbon steel components are treated with QPQ. In situations where the traditional surface treatments do not allow an acceptable performance but stainless steel can not be adopted, series Q offers an excellent performance/price relation together with all the advantages linked to the flat face design. Typical applications are: insecticides, diathermic oils, air conditioning fluids, water, etc.
