Recommended Bolt Torque

View recommended bolt torque specifications for KLAMFLEX couplings, including M12 and M16 bolts up to PN16. GRP pipe torque ratings require supplier consultation.

Recommended torque values based on coupling size and pipe type

Coupling Size Bolt Size Recommended Torque Pressure Rating
Up to 324mm OD M12 65–80 Nm PN16
Over 324mm OD M16 80–120 Nm PN16

GRP Pipe Connections

Torque ratings for GRP pipe connections are to be decided on after consultation with the specific GRP pipe supplier, as each supplier develops pipe with its own specific glass filament configuration.
