Swivel Coupler – P1137
48,3mm - 70mm

The swivel coupler, also known as thread coupling, RM or ERREM coupling. Connects two scaffolding tubes together. Tubes with a diameter of 48,3-70mm will fit in this Coupler.

With a coupling you can temporarily connect two pipes:

Universal joint: connecting two pipes at right angles to each other
Swivel joint: connecting two pipes at an angle
Welded couplings: connecting two pipes lengthwise
Beam couplers: Attaching a pipe to a steel beam

The connection is achieved by clamping the coupling to the pipes and striking the keys.

Standards

Van Thiel couplings comply with the standard NEN-EN 74-1:2005 / -2:2008 / -3:2007 couplings and accessories for steel tube scaffolding or have been subjected to comparable tests in-house.

Requirements and test methods:

Class B for universal joints, certified for use as a BB coupling
Class B for swivel joints
Class B for welding couplings Values obtained
by testing for beam clamps

Raw material

The raw materials used must meet the requirements set in the applicable Eurocode and/or the values as stated in NEN-EN-12811-2.

The raw materials are subject to controls according to the ISO 9001-2000 system.

Swivel coupler Uniqueness

Van Thiel couplings are recognizable by the stamped “EN74 B CU” mark in the coupling key.

Quality

The Van Thiel quality department checks the quality of the couplings through continuous process control and daily testing of the couplings.

Corrosion protection

The couplings are hot-dip galvanized and therefore protected against rust for life. Corrosion protection according to:

Sherardizing: NEN-EN 13811:2003 and NEN-EN-ISO 14713-1 and -3:2010
Galvanizing: NEN-EN-ISO 1461:2009

Swivel coupler Usage

Only use links to connect:

Two steel scaffolding tubes with an external diameter of 48.3 mm and a wall thickness in accordance with NEN-EN 39 or comparable
Two aluminum scaffolding tubes with an external diameter of 48.3 mm and a minimum wall thickness of 4 mm.

You must hit couplingswith a (500 grams van Thiel) hammer up to the ‘dead blow’ (NEN-EN 74-1).

Strike with normal force between one and three strokes.

You should inspect couplings visually before each use. Do not use the couplings if there is visible damage or deformation.
