Hose fittings classification and installation how to prevent leakage of hose fittings

When we use different types of hoses, we need to have a special connector for it to work properly. Among them, our daily household washing machines also use the hose joints to separate the waste water. Then, what are the hose connector classifications ? In the process of installing it need to pay attention to what issues? How can we buy a better quality hose fitting product? In fact, as long as the manufacturer of hose fittings on the line. In order to facilitate the purchase of hose fittings in the future, we will introduce to you the classification of hose fittings .

Hose fittings size

1. Pitch t=1.814

2. Thread outer diameter d=20.956

3. Thread diameter d2=19.794

4 thread diameter d1=18.632

5. Contour height h=1.162

Hose fittings classification

First of all, we classify hose fittings as assembly joints. There are sealing rings for contact surfaces with welded pipe fittings, and 24° flared snap fittings, spherical fittings, or angled taper fittings, and Card-type pipe connection fittings, with inch or US threaded connection, connection with 60° taper angle, hollow tube screw connection, with sealing groove and without sealing groove, etc. These are some of the common connector types in the industry. In life, we can also refine them into the form of diameter hose fittings for tubing and water pipes.

  

Hose connector price

Due to different brands and manufacturers of hose fittings, of course, the price of hose fittings will also vary. Hose fittings prices in more than ten dollars.

Note: This price is for reference only! Due to geographical differences, of course, the price will be different. For more details on the prices, please refer to the local distributors!

Hose fitting leakage prevention how to do

It should be noted that whether it is a metal joint or a hose joint, it is very easy to cause leakage problems. In most cases, the pipe is loose or deformed due to a large external force or impact force, so we must check the card frequently. Whether the sleeve is out of round and if the cutting edge is worn out, if the pipe end and the clamping nut are not pressed tightly, the external force of the pipeline will be in a state of tension, so that an over-expansion situation will occur. If it is because of the leakage of the hose joint caused by the damage of the two cone surfaces, the grinding surface needs to be ground with the grinding sand.

Hose connector installation precautions

For all types of hose fittings, we have to adopt different installation methods. Among them, when the hose is moving or stationary, we cannot allow it to bend excessively. We must bend it 1.5 times its diameter if the hose is During the installation process, it was pulled to its extreme position. We want to keep it loose. Too tight will make it distorted. If you are installing a high-pressure hose, remember to keep it away from the heat-radiating components, and if necessary, install insulation boards.

Editor's summary: In the process of using the hose, we must remember that do not let the surface of the same component be rubbed for a long time. The external damage caused by this will shorten the service life of the hose. We must know that only careful protection can make the hose. The service life of the connector is even longer!
