Hydralics fittings

High pressure hoses – flexible pipelines, which transfer energy by means of transportation of oils, emulsions and other hydraulic liquids. For connection of high pressure hoses with counterparts are used hydraulic fittings.

Fittings for high pressure hoses

Fitting for high pressure hoses – is a connecting piece of pipeline elements, being installed in the spots of bends, increasers and connections of tubes with different diameters.

Types of hose fittings

As a rule, systems with hose fittings can operate in temperature range from -20 up to +120°С for carbon steel and form -60 up to +200°С for stainless steel.
Hose fittings come under three series, depending on the tail type:

• Universal series – is used with all types of high pressure hoses (except spiral hoses).
• Interlock series – is used for crimping spiral hoses, however it is necessary to skive internal and external layers of the high pressure hose;
• CS series – is intended for crimping spiral high pressure hoses; there is no need to skive the internal and external layers of the hose.
