Hose fittings are highly dependent on the applications they are designed for. Considerable applications would be hydraulic applications and Pneumatic applications. Fittings used in hydraulic applications have to be resistant to the fluids they are transporting. Important features would be rust free and non-corrosiveness to chemicals. Fittings in Pneumatic applications require tight seals and need to be resistant to chemical corrosion as well as high pressures.Fittings can be differentiated for their connection types and functionality. Fittings can be connected to tubes through several means: Ball and Sleeve Fittings, Barbed Fittings, Cam-Lock Fittings, Crimp Fittings, Compression Fittings, End Fittings, Flange Fittings and Threaded Fittings. The types of fittings used are in turn affected by their functions. Fittings used to lengthen or shorten tube sizes comes in forms of coupling, union, cap and plug. Fittings altering the directions of tubes can be seen as elbow fittings, Tee, Wye and Cross Fittings. Fittings that interconnect tubes of varied sized come as reducers, and fittings providing specific connections take the form of nipple and valve fittings.Common materials for fittings are Aluminum (for its light weight and ability to resist corrosion), Brass (for its strength, grit, adaptability to high temperatures and good conductivity), Steel (its strength and heat resistance) and stainless steel (its high threshold to chemical and corrosion). 더 읽기 읽기 안 함
