Hydraulic hose fittings fall into various types, one of which is the coupling. Couplings can extend the length of a pipe’s run or even change the size of a pipe. The most basic couplings are categorized as permanent or reusable. They can come with female threads or be unthreaded. When looking at hose couplings, you quickly become aware that the three most common types are
- Threaded
- Mated angle
- O-ring
The choice of one type over the other depends upon the specifications of the coupling and the environment. The same is applicable to the material composition of the coupling. In fact, like any other type of fitting, the right choice depends upon several factors, including environmental ones. This is valid whether the company operates in Texas or Singapore.
Specifying Your Requirements
When looking for the right coupling for your hydraulic hose, engineers in Texas caution you to look beyond the correct size. When talking to a supplier, you need to supply the following information:
- Seat angle
- Type of seat: Is it inverted or flat?
- Thread pitch
- Maximum temperature
- Maximum pressure: This refers to the demands of the actual application. For example, higher pressure hydraulic hose systems most frequently use reusable over permanent couplings
- Flow
Overall, consider the configuration and the size while looking at what is the right coupling. The choice of material is also important when looking at hydraulic hose fittings. Connectors can be of metal or rubber, yet various durable plastic types are possible.
Hydraulic Hose Fittings: The Choice of Couplings
It is impossible not to stress the importance of choosing the right coupling for a job. Studies in Texas and research elsewhere indicates among the greatest number of hydraulic leaks are those resulting from employing the wrong type of fitting. Always talk to a knowledgeable supplier and engineer about what type of hydraulic hose fittings are the best fit for your equipment.
