JGD flexible rubber joint

Introduction

JGD flexible rubber joint is also called shock absorber,pipe shock proof box and soft joint etc.
It use the advanced foreign productive skill,and its working pressure is bigger than the general rubber joint .Due to the inner glue received the high presurre and made the nylon combined with the glue.The characteristic : the inner and outter glue is one integrated mass, none-sealing , the label grave on the rubber body.The rubber joint is soft connector of metal pipe.It is make up of inner glue,jinlun curtain thread, outer glue and floating metal flange.It can resistance the high temperature ,good felxibility, huge displacement, reduce the noise , easy installate and so on. Beacause its integral function ,felxible rubber joint can be wildly used in chemical industy, construction, water supply, drainage,petroleum, weight and light industry, refrigeration, health,water heating.fireproof , power and so on. The general rubber joint just use to -15`C ~ 115`C tomsphere, water, sea water, petroleum,acid,alkaliand so on.The special style rubber joint can used to all the refer meduim or oil,strong acid and alkali.
