Technology Question
1.What is the working pressure(W.P.) and burst pressure(B.P.)?
Working pressure is the pressure you can operate with for a given specific type of hose. The burst pressure is usually, depending on material, usually 3 to 4 times the working pressure and is the amount of pressure a hose would be able to withstand if there were a pressure surge on the air line. Both the working pressure and burst pressure are given at  specific temperatures.
a), Suggest that the hose be used within its recommended temperature and pressure range. Consult with the company when it is necessary.
b),  A hose expands and contracts according to the change of its internal pressure and temperature. Cut the hose slightly longer than it is needed.
c), When pressurizing, slowly open or close any vales to avoid impact pressure and protect the hose from being damaged.
d), Choose a suitable hose according to the applications and conditions of  the hose when used under minus pressure. Consult with the company when it is necessary.
2.Is there any difference between flexibility and durometer?
Flexibility is a subjective characteristic, impacted not only by durometer but also by the bend radius (which is a function of wall thickness and material properties). In other words, a softer durometer does not always equate with higher flexibility.
3.How about the bending of your hose?
a), Never use a hose at less than its minimum bend radius, which is fours times of the diameter of the hose. If using a hose at too small bend radius, it may break or short the lifetime of the hose.
b), When transferring powers and particles, enlarge the bending radius as much as possible according to the situation.
c), Do not use a hose at its extreme bend radius when fixing metal fittings.
