EPDM Flexible Single Sphere Rubber Expansion Joint Outstanding Pressure Resistance

Plumbing fittings single sphere ansi flange neoprene flexible rubber joint


ADVANTAGES of rubber joint

1.Outstanding pressure resistance

It excels in pressure resistance by the combination of spherical structure with super stability against internal pressure and strong special reinforcing nylon.JINGNING flexible connector display an outstanding pressure resistance of bursting pressure.


2.Superior absorption of vibration-noise-shock

JINGNING single sphere flexible rubber joint are engineered to reduce vibration ,noise and movenment inherent in piping systems.JINGNING will enable the isolated equipment to move freely ,eliminating vibration and repelling sound which is prevalent in metallic type joint.


3.Compensate greater elongation, compression , lateral and angular movement

Equipment such as pump ,chillers,cooling tower,compressors and piping systems move out of alignment due to wear,load stress and during the setting of foundation blocks.JINGNING flexible connector for lateral ,torsional and angular movement to prevent damage ,which elimate costly downtime in plant operation.


Expansion joints for piping systems are flexible connectors, made out of PTFE, natural or synthetic elastomers, with combinations of rubber, fabric and metal reinforcement. Expansion joints installed into piping systems will help solve problems such as:

  • Stresses - expansion joints absorb movement due to thermal expansion and contraction of pipes, wear, load stresses and settling of supports and foundations
  • Misalignment - custom expansion joints can be manufactured with offsets to account for installation errors in pipe alignment, or for movement and settling over time
  • Abrasion - with proprietary elastomers such as ABRA-LINE, abrasion can be significantly reduced compared to other rubber or metallic connectors
  • Vibration - rubber expansion joints significantly reduce vibration when installed in proper locations and are not subject to metal fatigue failure
  • Noise - transmission of sound is reduced as the expansion joint acts as a dampener and absorbs the noise levels
  • Shock - effects of pressure surges, water hammer, or pump cavitation are resisted
  • Corrosion - no metal to metal contact eliminating electrolysis between dissimilar metals
  • Space - greatly reduced space required compared to expansion bends or loops
