Making quick coupling with the material of what?

Quick coupling most is made of copper to do, of course, also have part use a stainless steel or carbon steel, the major is hydraulic quick coupling. And some have iron to do, the surface has electroplating, but is easy to rust, but cost is lower, to pay attention to choose suitable products. Choose quick coupling and rapid water mouth, if is better products, copper plane is smooth, no sand holes, color is more bright. Of course, there are the general quality, this should see his own need to decide. Stainless steel quick coupling than copper high cost, this is mainly because production process complex and production speed is slow. Use quick coupling and rapid water mouth, joint and water mouth connection can't have sundry, so as not to affect the service life, often can add some grease facilitate connection.

1, material: said the mother of quick die joint production of male connector and joint material.

2, sealing material: say quick die union seal parts of the o-rings material, general is with butyl, have always used a fluoride apron (high temperature resistant 200 degrees)

3, temperature: used for quick die on joint said o-rings material to the highest temperature and minimum temperature.

4, automatic open closed: said connection of valve automatically switch structure. Open-said female head and male head no valve structure; Enclosed-said female head and male head have valve structure, in case of female head and male head apart tube fluid flow won't.

5, pressure: said in the use of die quick coupling, the pressure range of allowing value.
