The metal hydraulic adaptors joint classification

Metal hose bellows are two, one is a spiral-shaped bellows; another annular bellows.hydraulic hose assemblies
Spiral corrugated pipe
Helically corrugated tube is corrugated Movement spirally arranged cylindrical housing, a helix angle between two adjacent corrugated, all of the corrugations can be connected by the coil.hydraulic hose cutting machine
Bellows
Closed annular bellows the corrugated tubular housing between the wave and wave annular corrugated series. Bellows molding seamless pipe processing. Processing limitations, single pipe length is usually shorter than the spiral bellows. The advantages of the annular corrugated tube is a good flexibility, rigidity is small.metric hydraulic fittings
