Product catalog summary

Tightening Torques for Screw-in Threads

This document provides the recommended tightening torques for screw-in plugs made of steel, applicable to various thread types including metric, UNF, and imperial threads with O-ring seals. The torques are specified for different series and pipe thread sizes.

1. Metric Thread with O-Ring Seal

Series L: Torque values range from 15 Nm for M10x1 to 260 Nm for M48x2.
Series S: Torque values range from 35 Nm for M12x1.5 to 420 Nm for M48x2.

2. UNF Thread

Series L: Torque values range from 19 Nm for 7/16-20UNF to 340 Nm for 1 7/8-12UN.
Series S: Torque values range from 21 Nm for 7/16-20UNF to 430 Nm for 1 7/8-12UN.

3. Imperial Thread with O-Ring Seal and Chamber Ring

Series L: Torque values range from 25 Nm for G 1/8 A to 600 Nm for G 1 1/2 A.
Series S: Torque values range from 50 Nm for G 1/4 A to 600 Nm for G 1 1/2 A.

4. Metric Thread with O-Ring and Chamber Ring Seal

Series L: Torque values range from 15 Nm for M10x1 to 260 Nm for M48x2.
Series S: Torque values range from 35 Nm for M12x1.5 to 420 Nm for M48x2.

General Notes:

The specified values apply only to steel couplings (galvanized) and the mentioned counter-materials.
Screw-in plugs should 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 require securing the coupling against external loosening torques.
