Temperature Couplings

Safety without Compromise for Temperature Regulation Applications

Plastics processing companies rely on particularly robust, resilient and temperature-resistant couplings and fittings. The reason: They are used to cool and heat moulding units during injection moulding or pressure casting and have to withstand extreme temperatures.

LÜDECKE offers an extensive product range for these demanding temperature regulation applications, consisting of quick connect couplings (European and International plug profiles), SoftFlow material conveying quick connect couplings, screwings and components, manifolds as well as hose clamps and hose clips.

The highlight: with the patented TempSecure by LÜDECKE® program, we guarantee simple and effective protection against unintentional decoupling under pressure.


  • High-class material (brass, stainless steel)
  • Robust, safe and reliable
  • Completely leakage-proof and durable
  • Easy to couple
  • Various sizes, connection and valve types
  • Particularly safe and flexible solutions for temperature regulation applications (especially for high temperature applications)
  • TempSecure by LÜDECKE®: patented coupling system

TempControl by LÜDECKE® - Intelligent Technology for Maximum Safety

The new TempControl quick connect coupling system features an innovative thermo colour coding.
It warns the operator of hot media as well as high surface temperatures of the coupling and thus offers reliable protection against injuries.

Presenting the new TempControl quick connect coupling system, LÜDECKE is offering an additional innovation for the temperature regulation technology and high-temperature applications.

The TempControl system is based on the tried and tested TempSecure principle: It prevents unintentional disconnection and unlocking using an automatic safety locking mechanism.
However, the safety coupling has now been added by a revolutionary feature: a thermo colour coding.
This not only indicates correct and secure connection (plain = disconnected, colour = connected), it also warns the operator of hot media as well as high surface temperatures of the coupling and thus offers reliable protection against potential injuries.

How is that possible?
The colour coding of the TempControl by LÜDECKE® quick connect coupling system indicates the current temperature of the coupling surface. When the temperature falls below +40°C, the colour coding turns blue - the coupling can be touched without any precautions. When the tempera¬ture rises above +40°C the coating reacts. The dark blue surface turns red warning against potential burns.*

This coupling is especially suited when using critical media as well as for extreme temperatures between -20°C and +220°C (subject to media). High-quality FKM O-rings prevent leakages in high-temperature applications.
The TempControl system can be transferred to almost all LÜDECKE temperature regulation series and is available in various sizes, materials, types of connections and valves.

*Important note: The colour coding represents the surface temperature of the coupling and serves as visual aid. However, the temperature of the media is not measured. At all times, it is the operator/ user who is responsible for safe and proper use of the product. In case of couplings with free passages, please turn off the media flow before disconnection.
