100TONG RK-001 Grooved Rigid Coupling 4″
Rigid, pressure-tight pipe connections built for demanding fire safety and process lines.
The 100TONG RK-001 Grooved Rigid Coupling delivers a safe connection solution with high pressure and temperature resistance. In addition, it mounts easily on grooved pipes, and its rigid structure prevents axial misalignment. Consequently, compliance with ISO 6182 and UL 213 standards makes it a preferred choice in fire safety systems, operating from -50°C to +150°C.
The body is made of GGG 40.3 ductile iron, providing high impact and corrosion resistance. Moreover, the EPDM gasket keeps its flexibility across the -50°C to +150°C range. Therefore, the rigid design resists vibration and misalignment while the maximum application pressure reaches 300 psi (20.7 bar) with high sealing performance.
