Product catalog summary

Tightening Torques for Screw-in Threads

1. Introduction
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 B standards.

2. Imperial Thread Specifications
2.1. Series L
- Pipe outer diameters range from 6 to 42.
- Pipe threads include G 1/8 A to G 1 1/2 A.
- Torque values vary based on material: Steel, Aluminium F22, F28, and F45.
2.2. Series S
- Pipe outer diameters range from 6 to 38.
- Pipe threads include G 1/4 A to G 1 1/2 A.
- Torque values are specified for Steel and Aluminium variants.

3. Metric Thread Specifications
3.1. Series L
- Pipe outer diameters range from 6 to 42.
- Pipe threads include M 10x1 to M 48x2.
- Torque values vary based on material: Steel, Aluminium F22, F28, and F45.
3.2. Series S
- Pipe outer diameters range from 6 to 38.
- Pipe threads include M 12x1.5 to M 48x2.
- Torque values are specified for Steel and Aluminium variants.

4. General Notes
- Values apply only for steel couplings (galvanized) and specified counter-materials.
- Screw-in plugs must be greased before installation.
- Assembly torques have a permissible tolerance of ± 10%.
- Deviations in tightening torques can affect maximum operating pressure.
- Reduced torques require securing against external loosening forces.
