100TONG RK-001 Threaded Rigid Coupling 5″
Leak-proof, fixed pipe connections for high-pressure and high-temperature systems.
The 100TONG RK-001 Threaded Rigid Coupling delivers a leak-proof, fixed connection solution for 5″ pipes. In addition, it mounts easily onto threaded pipe ends. Moreover, its rigid structure prevents axial movement between pipes.
The EPDM gasket maintains flexibility between -50°C and +150°C, providing reliable sealing. Furthermore, a PN25 nominal pressure rating allows safe operation up to 25 bar. The rigid body ensures the connection stays fixed even under vibration and impact. As a result, assembly is quick and requires no special tools.
