What Are Hydraulic Hose Swivels? Why Hydraulic Hose Swivels?

Most hydraulic engineers are well aware that proper hose routing usually means adapting to the movement of the machine without putting too much pressure on the hose. It will not cause friction and wear out other hoses or machine components. Otherwise, hoses may fail prematurely, resulting in leaks, machine damage, downtime, costly environmental pollution, and possible danger to nearby personnel.

The design of the swivel-type fitting allows the coupling to be connected to the hose, thereby preventing twisting, kinking, and excessive bending. This can extend the life of the hose and reduce maintenance requirements. It can also improve the efficiency of the system. The use of swivel joints can shorten the length of the hose required between connections, no need to bend the pipe to accommodate the angle connection, and it can usually be directly connected to the hose without an adapter.

Because swivel joints move, they can compensate for hose length changes when the system pressurizes and absorb hydraulic surges and shocks in a line.

Therefore, the use of hydraulic hose swivel joints can benefit many applications. These components allow a wide range of articulation and movement during device operation. At the same time, it also eliminates torque and distortion in hydraulic hoses. Hydraulic hose swivel joints can also simplify hose installation and maintenance.

Hydraulic swivels are widely used in rotary applications. Typical examples include grabs, forestry attachments, cranes and multi-lift trucks, railway maintenance equipment, demolition shears, and mobile excavators. The cost of a swivel joint can be more than offset by cost-reduction benefits such as greater system design flexibility, improved system routing with less hose, simpler and quicker installation, fewer adapters and tube fittings, and longer service life.
