Frequently asked questions about the use of polyester/cotton woven sleeves

The stress-bearing capacity of polyester/cotton braided sleeves mainly lies in the inner layer and the middle braided layer (polyester fabric extension layer). If the installation is not reasonable during the use process, the airflow will enter the inner layer between the inner layer and the outer layer. At this time, the rubber hose mainly relies on the outer layer to bear the force, which will greatly reduce the stress-bearing capacity of the Polyester/Cotton Braided Sleeve, and cause the tube body to crack (such cracks are usually caused by the outer layer being damaged while the inner layer is intact).

If the Polyester/cotton Braided Sleeve is used with a jacket-type quick connector, or a threaded joint/hose hoop with burrs or burrs, it may cause the polyester/Cotton Braided Sleeve to be delaminated and cracked.
We can see that when the jacket-type quick connector is used to insert the polyester/cotton Braided Sleeve, the key is to rely on the tightness of the outer layer. In such a case, gas can easily escape from the inner layer, causing the outer layer to explode and tear down the pipe body.
Minimize the use of polyester/cotton braided sleeves with jacket-style quick connectors that are sealed by the outer layer.
If you find that the outer layer of the polyester/cotton braided sleeve is cracked or the tube part is cracked during use, please check whether you have used a coat-type quick connector and whether there are burrs and burrs on the connector and hose hoop.
If you want to use a coat-type quick connector, it is recommended to use a single-sided double-headed PU tube if the working pressure is allowed.
Common problems when installing polyester/cotton braided sleeves:
1. When inserting the threaded joint, please do not apply vegetable grease or heat it with fire on the threaded joint of the hose. Please use a small amount of warm water to heat the hose before installation.
2. Please use a connector with a suitable hose specification, cut the wound and insert the hose as much as possible. Be careful not to use connectors with burrs, burrs or scars or rust.
3. Please use a hose clamp of appropriate size, do not use fake and inferior hose clamps with burrs and burrs.
4. Avoid using steel wire instead of hose hoop, and prevent excessive tightening of the hose.
5. Do not use jacket-type quick connectors for polyester/cotton braided sleeves, otherwise it is easy to cause the rubber hose to be delaminated and cracked.
