Short-Length Pipe Test Plug for Confined Spaces – PUK Series - Inflatable Bypass Plug

These compact inflatable pipe test plugs are ideal for use in confined spaces. They are particularly well suited for inlets with short spigots or for installation in complex, angled separator systems. In bypass applications, the integrated flow‑through allows wastewater to pass safely while the pipe section is securely isolated, enabling maintenance, inspection or cleaning work to be carried out without interrupting operation. For this reason, pipe plugs from the PUK series are our first choice for temporary isolation with controlled bypass flow. The shut‑off bladders are manufactured from high‑quality rubber with fabric reinforcement. All metal components are corrosion‑resistant. Various sizes are available for pipelines with diameters ranging from 50 mm to 400 mm. For special requirements, we also offer an oil-resistant version of this sealing cushion. Our pipe stoppers and shut-off plugs are made of expandable material and can be filled with liquid or air.
