Type of hydraulic connector
Hydraulic pipe fitting are divided into two types: hose fittings and hard pipe fittings.
Each of these two categories can be divided into several subcategories:
1)Hose fittings are divided into integrated hose fittings, buckle hose fittings and internal lock hose fittings.
Hose connectors, detachable hose connectors, etc.
2) Hard pipe fitting, also known as transition fittings, is divided into DIN card sleeve, metric thread fittings.
British thread fittings, American thread fittings, welding flange, mining fittings, etc.
There are several thread conventions for hydraulic fittings.
Type A is A flat cut.
The H-type is an internal magnification of 26 degrees.O type is flat head can put O ring
Type C is the 60 degree Angle of the inner cone, commonly known as the concave, also known as the expansion.
Type D is the outer ball head.
Specializing in the production of various specifications of rubber hose fittings (metric, British, American), large fittings (metric, British, American), coal mine fittings, engineering machinery fittings, welding pipe fittings, sleeve fittings, mine accessories, hydraulic fittings, oil, all kinds of processing parts. S special connector, according to user needs to produce a variety of non-standard products
We are hydraulic hose fittings manufacturer.
Leakage prevention of high pressure rubber pipe fittings
In hydraulic systems, there is a simple leakage problem in both metal and hose fittings. For jacketed pipe fittings, due to the larger external force or impact, most of the fittings leak, resulting in jacket loosening or pipe end deformation. At this time, it should be checked whether the jacket is out of circle, whether the edge is defective, whether the tube end is defective, whether the jacket nut is pressed, and so on. At the same time, the external pressure of the pipeline should be eliminated. For flaring pipe fittings, due to the flaring is too large, poor quality or repeated disassembly, most of the leakage, resulting in flaring deformation or crack. At this fittings, the front end can be truncated and flattened from scratch. If the male cone and female cone top pressure seal, the leakage is mainly due to the damage of the two cones. The cone can be polished with a scrub. In some cases, the “” ring is sealed by the end face or outside diameter.
