Rubber Expansion Joint for Pipelines – Flexible, Chemical-Resistant & Durable

Rubber expansion joints are ideally suited to protect the pipeline from temperature stresses as well as vibrations and thus help to avoid annoying defects or a cost-intensive system standstill. Our OG series rubber expansion joints are universally applicable and absorb lateral as well as angular and axial vibrations and reliably dampen them. In addition to our standard expansion joints with bellows made of EPDM or NBR in conjunction with galvanised steel flanges or also socket connections, we can also offer special combinations. For example, our PTFE or Hypalon-coated expansion joints with stainless steel flanges are almost indispensable for the chemical ...

Rubber expansion joint: flexible pipework accessories

A rubber expansion joint is an indispensable component in pipework systems that compensates for movements, vibrations and thermal expansion to prevent damage to the pipework. With flanges made of stainless steel or steel for secure fastening, the EPDM or NBR sleeves offer high resistance to various media. Thanks to its flexibility and durability, the rubber expansion joint is available in various sizes from DN20 to DN400 and is often offered wholesale to B2B customers looking for a reliable and long-term solution.

Socket Rubber Expansion Joint – compact flexibility for pipelines

The socket rubber expansion joint quietly protects your system from vibration, stress, and thermal movement. Its two-convolution design absorbs motion effectively, while BSPP female threads make installation straightforward—no special end prep required.

With a compact overall length of 203 mm, it fits tight spaces with ease. The EPDM bellows, nylon-reinforced, offers excellent resistance to hot water, steam, and many process media, yet stays elastic enough to handle axial, lateral, and angular deflection.

Ductile iron (nodular cast iron) flanges, electro-galvanized, provide a sturdy, corrosion-protected connection. That means steady performance at a max. operating pressure of 16 bar and temperatures from −10 °C to +110 °C.

In short: compact, easy to install, and built to last—just the kind of component that takes real stress off a pipeline.
