The aviation hydraulic fitting is one of the most important components which directly affects the safety and reliability of aircrafts.A comprehensive overview was intended to introduce the general features of the aviation hydraulic fittings.The performance of three main types of aviation hy-draulic fittings was demonstrated,including permanent fittings,separable fittings and boss fittings. The structure,principles,applications,design standards and suppliers of each type were illustrated. The characteristics of each main type fitting such as pressure resistance,pull-off strength,weight and installation,were analyzed and compared.The recommended selections of aviation hydraulic fittings for different pressure levels were summarized.Finally,the developing prospect of aviation hydraulic fittings was given,and the large distance in the aviation hydraulic fittings between China and the in-ternational advanced level was pointed out.
