Product Description

Double Sphere Rubber Bellows/ flexible rubber expansion joint,2018 most popular ball rubber expansion joint fittings bellow coupling

 

 

Product Feature

• The rubber joint can greatly reduce pipeline system vibration and noise, can solve the problem of joint displacement, axial expansion, etc.

• According to different materials, it can be made into many kinds, adapt to many mediums and different environment.

• Good sealing rubber, light weight, easy installation, long service life, and avoid contacting with sharp metal device.

• If use overhead, can match with elastic support.

• If pipeline pressure is high, should use bolt connect the flange both ends.

Why Choose US





We test leakage of each roll before braiding, then we cut 300mm and crimp it to test
burst pressure after brading.

We use CNC Lathes Machine for end fittings production. Machine system, knife and inspection
tools are all imported from Japan.

We use Techmaflex Crimping Machine which is imported from France. This machine has
accurate and stable performance for crimping because it is produced for PTFE hose crimping only.
