Product Description

WRAS Single Sphere Rubber Bellows,2018 most popular ball rubber expansion joint fittings bellow coupling

 

Rubber expansion joint advantage:

 

A: 15 minutes zinc plating, high pressure resistance, high temperature resistance, oil resistance, wear resistance, corrosion resistance, acid and alkali resistance. 

B:Connect with pump, valve, fire fighting equipment, pipe which vibrate big, pipe which hot and cold change frequently.

C: Natural rubber content of forty-seven percent, can continue to use for 15 years without aging.

 

 

The form: this rubber expansion joint consists of rubber pipe, made of inner glue, multi-layer proofinf and cord fabric and outer glue abd metal woggle joint.
It is applicable for the connection of inlet and outlet pipes of various fancoil sets of air conditionings in the guest rooms of hotels and restaurants.

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.
