Hydraulic couplings Cheap MLB Jerseys From China , also known as fittings,play an important role to hydraulic equipment. Couplings are the devices that are used to connect the hoses to the hydraulic system. The hydraulic machinery will not be able to perform without a secure connection for the fluid to be pushed through. Generally couplings are made out of metal and are attached to hydraulic hose assemblies. There are two components to a coupling, a stem end and a thread end. The stem end attached to the hose and thread end is joined to the hose assembly and hydraulic equipment.Depending on the type of hose and fluid pressure passing through it, different coupling are used. There are a variety of ways to attach couplings when making hydraulic hose assemblies. Thread configurations on couplings come in two types: male and female. To establish conformity in the industry, thread ends were standardized. Today there are three principle types of hydraulic seals that thread end designs can conform to: thread seals, mated angle seals and “O-ring” seals. The first two use metal-to-metal contact to seal and the latter Cheap MLB Jerseys China , “O” Rings, use a rubber-to-metal seal. The easiest couplings to install are ones used with low-pressure hoses. These couplings are simply lubricated and pushed into the hose end. As the hose tightens under pressure, the angled ridges on the coupling grip the hose. Hoses that are designed for high pressure use both reusable and permanent couplings. |
