Universal Tricoise Wrench 3929.781 - Non-sparking copper alloy DN 20-65
This universal wrench is made from a non-sparking copper alloy, making it suitable for use in potentially explosive or spark-sensitive environments. It covers nominal diameters from DN 20 to 65, and its universal spiral shape means it can be used on a wide range of fittings quickly. Ideal for fire-fighting supplies, maintenance work or industrial fluid installations.
Technical specifications
- Part no.: 3929.781
- Type : Universal wrench
- Material : Spark-proof copper alloy

- Standards / environment : Suitable for explosive or spark-sensitive environments
Benefits
- Increased safety: non-sparking material reduces the risk of ignition in environments with delicate atmospheres.
- Versatility: covers a wide range of DN 20-65 fittings, one wrench for several diameters.
- Reliability: designed for professional use (fire department, fluids, industrial maintenance).
- Ease of use: universal braid shape for good tightening/loosening torque on standardized fittings.
- Explosion-proof: non-sparking copper alloy, ideal for ATEX zones
- Corrosion-resistant: suitable for wet, salty or chemical environments
- Robust and durable: excellent wear resistance, even in intensive use
- Industrial compliance: meets the requirements of high-risk sectors
Application
This wrench is particularly suitable for :
- Fire-fighting operations where DN 20 to 65 fittings need to be handled.
- Maintenance of hydraulic or fluid transfer installations requiring non-sparking equipment.
- Industrial or sensitive environments (ATEX zones, potentially explosive atmospheres) where safety is paramount.
How to use: Select the correct fitting size within the DN range covered, position the wrench on the fitting, apply the appropriate torque to loosen or tighten, then check the installation for tightness before re-commissioning.
Fields of application:
Oil and gas industry Refineries and ATEX zones Industrial maintenance Chemical and pharmaceutical industry Marine, offshore and naval environments Power plants (thermal, nuclear, etc.)
