High-quality high-pressure hoses offered by the link https://ukrrezina.com.ua/g90928292-rukava-vysokogo-davleniya by the" Ukrgum Plant "company, they consist of reliable chemical-resistant rubber and several layers of metal braid (it can also be wound), and are completed with special metal fittings. Since the high pressure hoses are designed to work under heavy load, the connecting fittings are crimped using special equipment. This ensures that the fitting won't fail at a critical moment.
However, craftsmen claim that you can squeeze the high-pressure sleeve with your own hands. How to do it and whether it is worth it you will learn from this article.
Metal Braided High Pressure Hose Clamps
Jack of all trades use universal clamps for crimping hoses with a metal braid:
There is also a demand for a power clamp fixed on two bolts. It is recommended for use when it comes to a particularly rigid high-pressure hose with a multi-layer winding. The very principle of pressing in with the help of these improvised means is quite obvious.
However, this is unacceptable in industry, since it contradicts safety regulations.
Ideally, you should have: a suitable machine (or die), a press nipple and a special ferrule. We insert the nipple into the hose, put on the coupling and perform the compression with a hydraulic machine. Moreover, it is enough to correctly insert the element into the equipment jaws and gradually pump it up. The machine will do everything by itself.
You can also simply order a finished product that meets the requirements of GOST 6286-73 in the Ukrgum Plant catalog.
Is it worth it to crimp hose fittings with winding with your own hands
Although there are several ways to crimp metal braided high pressure hoses, experts strongly advise against doing this. The fact is that it is almost impossible to achieve an ideal result without the use of special equipment. That is, "on the knee" it will not be possible to do it. Of course, if a winding hose is used not for a hydraulic installation operating under high pressure, but, say, for garden irrigation (where the pressure is low), a few clamps will really be enough. But this:
misuse of specialized hoses;
extra financial costs.
And if you need to crimp the hose fittings for the subsequent pumping of engine fluids under high pressure, doing it yourself is not only unproductive, but also very dangerous.
