Marine Straub Pipe Coupling Flex Type NBR 40A (47-50mm Pipe OD)

The Marine Straub Pipe Coupling Flex Type is a versatile pipe joint designed for rapid, weld-free connections in shipboard piping systems. Featuring a durable NBR (acrylonitrile-butadiene rubber) sleeve, this coupling is ideal for handling oil and organic gas media. The Flex-type design provides excellent pipe alignment flexibility and vibration absorption, ensuring reliable performance in demanding marine environments.

Constructed with a robust housing (available in stainless steel SUS 316 or SUS 304), bolts, nuts, and washers, this coupling delivers a secure, leak-proof connection without the need for specialized tools or welding. Suitable for nominal size 40A pipes with an outside diameter range of 47-50 mm, it operates at a working pressure of 10 bar (max 16 kgf/cm²). Perfect for quick repairs, system expansions, or vibration isolation in engine rooms, fuel lines, and other critical ship systems.
