Short Flow Pipe Sealing Cushions, Oil-Resistant PUOEL
Flow pipe sealing cushions designed for use in confined spaces. Especially at inlets with short pipe sockets or in complex separator systems, the PUOEL flow pipe sealing cushion is the first choice. PUOEL flow pipe sealing cushions are made from high-quality rubber material with fabric reinforcement. All metal components are corrosion-resistant.
Versions are available with diameters ranging from 50 mm to 300 mm. Our pipe sealing cushions and blocking bladders are made of stretchable material and can be filled with either liquid or air.
