Product catalog summary

Tightening Torques for Screw-in Threads

Imperial Thread (DIN 3852 Form A)

The document specifies the tightening torques for screw-in plugs with imperial threads, applicable to steel materials. The torques are categorized by series and pipe outer diameter:

Series L: Ranges from 10 Nm for G 1/8 A to 320 Nm for G 1 1/2 A.
Series S: Ranges from 40 Nm for G 1/4 A to 320 Nm for G 1 1/2 A.

Metric Thread (DIN 3852 Form A)

The document also provides tightening torques for screw-in plugs with metric threads, applicable to steel materials:

Series L: Ranges from 10 Nm for M 10x1 to 320 Nm for M 48x2.
Series S: Ranges from 25 Nm for M 12x1.5 to 320 Nm for M 48x2.

Notes:

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