| Four simple steps to teach you to select rubber joints: | 
| 1. Look: whether there are depressions in the inner wall, no depressions can not achieve the expansion effect | 
| 2. smell: excellent rubber joints do not have a pungent smell | 
| 3. Weight: excellent joints are heavy, with sufficient materials | 
| 4. Sturdiness: when stepping on it, a small rubber joint can support the weight of an adult and will not collapse | 
| Basic information of rubber joint products | ||
| Product Name | Double sphere rubber expansion joint | |
| Characteristics | 1.The form: this product consists of rubber pipe, made of inner glue, multi-layerproofinf and cord fabric and outer glue abd metal woggle joint. 2. Small size ,light weight,good elasticity,easy to install. Characteristics 3.lt can absorb lateral, axial and angular displacement caused by pipe vibration after instalation,and is not limited by pipe's non-concentric and non-parallel flange. 4 .When working,the structure can be reduce noise transmission and strong vibrationabsorption ability. | |
| Application | It is applicable for the connection of inlet and outlet pipes of various fancoil sets of airApplication in the guest rooms of hotels and restaurants. | |


Double sphere rubber bellows coupling is generally consist of the inner and the outer rubber
layer and fabric reinforced layer (the enhancement layer has a multilayer spreading cord fabric),
vulcanization molded in high temperature and high pressure , then assembly together with rubber
tube and metal flange or parallel joint sleeve.It is mainly used for pipeline, pump and valve
connection etc,applicable media could be air,compressed air,water,sea water,hot water,oil,acid
and alkali etc.
