We are professional hydraulic fittings manufacturers. Hydraulic fittings are the part connecting high-pressure oil pipe and high-pressure oil pipe in the hydraulic system. Hydraulic fittings can be divided into the hydraulic hose, high pressure ball valve, quick joints, pipe connector of cutting sleeve type, welded pipe, high pressure hose, transitional type pipe, pipe fittings, non-standard type three-pass pipe joint, flaring pipe, rectangular pipe joints, rotary pipe joint, quick joints, stainless steel pipe, copper connectors.
Hydraulic Welded Fittings
Use nozzles to weld pipes. The O-ring end seal is used between the fittings body and the nozzle. Simple structure, easy to manufacture, good sealing, the accuracy of the pipe size is not high. High quality welding requirements, inconvenient assembly, and disassembly. Working pressure up to 31.5mpa, working temperature -25 ~ 80℃, suitable for oil as the medium of the pipeline system.
Ferrule-type Compression Hydraulic Fittings
This type of fittings needs high level hydraulic fittings manufacturers to process . Using the clamping sleeve deformation stuck pipe and seal, advanced structure, good performance, light weight, small volume, easy to use, widely used in the hydraulic system. The working pressure can be up to 31.5mpa, requiring high precision of pipe size, cold-drawn steel pipe is required. The accuracy of the sleeve is also high. Suitable for oil, gas, and general corrosive medium pipeline system.
Flare Fittings
This type of fittings needs good hydraulic fittings manufacturers to process it. Use the pipe end flaring for sealing, no other seals. Simple structure, suitable for connecting thin-wall pipe fittings
Suitable for oil, gas medium for low pressure pipeline system, allow the use of pressure.
Insert Welded Hydraulic Fittings
Insert the pipe with the required length into the fittings until the end of the pipe contacts the inner end of the hydraulic fittings, and weld the pipe and the pipe joint into a whole, thus eliminating the need to take over, but the pipe size is strictly applicable to the pipeline system with oil and gas as the medium.
Cone-sealed Welded Hydraulic Fittings
One end of the pipe is the outer cone surface with an o-ring sealing ring matching the inner cone surface of the joint body, screwed. Working pressure up to 16 ~ 31.5mpa, working temperature -25 ~ 80℃ Suitable for pipeline system with oil as a medium.
Crimp Type Hose Fittings
Easy to install, but added a tightening process. After the rubber hose is damaged, the joint coat can not be reused, and the steel wire braided rubber hose form a complete set. Can be used with an o-ring seal welded pipe joint. Suitable for pipeline system with oil, water, and gas as a medium. Medium temperature: oil: -30 ~ 80℃; Air, -30 ~ 50℃; Water, below 80℃.
Three-flap Hydraulic Hose Fittings
It is not necessary to strip the outer rubber layer of the hose during assembly. The hose with a slightly different outer diameter is compensated by the amount of pre-compression of the hose by the fittings jacket. The pre-compression of the hose in the range of 31% ~ 50% can ensure no leakage under working pressure, no glue pulling, no fracture of the outer rubber layer. It is suitable for a pipeline system with oil, water, and gas as a medium. Its working pressure and medium temperature are limited by the connected hose.
Quick Release Fittings (both Ends Open and Closed)
After the pipe is disassembled, it can seal itself and the liquid in the pipe will not be lost, so it is suitable for frequent disassembly occasions. The structure is complex and the local resistance loss is large. Suitable for pipeline system with oil and gas as a medium, working pressure below 31.5mpa, medium temperature -20 ~ 80℃.
Quick Change Connector (open at Both Ends)
Suitable for pipeline systems with oil and gas as a medium, its working pressure medium temperature is limited by the connected hose.
