Product catalog summary

Tightening Torques for Screw-in Threads

This document provides the specified tightening torques for screw-in plugs made of steel, applicable to both imperial and metric threads as per DIN EN ISO 9974 and ISO 1179 Form E standards.

Imperial Thread Specifications

The table lists the tightening torques for various pipe outer diameters and thread sizes, with values provided for steel and different aluminum grades (F22, F28, F38, F45).
For example, a G 1/8 A thread with a 6 series pipe has a torque of 18 Nm for steel and varies for aluminum grades.

Metric Thread Specifications

Similar to the imperial section, this table provides torques for metric threads, such as M 10x1 for a 6 series pipe, with corresponding values for steel and aluminum grades.
For instance, a M 10x1 thread has a torque of 18 Nm for steel and varies for aluminum grades.

General Notes

The values are applicable only for galvanized steel couplings and specified counter-materials.
Screw-in plugs must be greased before installation.
Assembly torques have a permissible tolerance of ±10%.
Using reduced or higher torques can affect the maximum operating pressure and may require securing the coupling against external loosening torques.
