Ring Flexible Coupling
Key Features
The Ring Flexible Coupling is designed to join plain-end steel pipe with ring grooves, fittings, and valves in mining and industrial piping systems.
Its flexible pipe joint design allows controlled expansion, contraction, and deflection, helping accommodate movement within the pipeline while maintaining a reliable, leak-tight connection.
GOLDDRILL supplies Ring Flexible Coupling in DN50-DN250 (2"-10"), with ductile iron housings and standard epoxy powder coating for demanding industrial and mining applications.
