WEICON Frost-Proof Leak Detection Spray 400 ml

WEICON Frost-Proof Leak Detection Spray 400 ml is an aerosol technical spray developed to make gas leaks in pressurized lines visible quickly and safely. It works by creating foam/bubbles on the application area, making it easier to visually identify the leak point. Its frost-resistant formula supports continuity during field inspections at low temperatures. The product is developed by WEICON GmbH & Co. KG, based in Germany.

Frost-resistant leak detection with the WEICON leak detection spray
This technical spray has a special formulation aimed at making even “micro leaks” visible, especially in gas lines and pressurized systems. If there is a leak on the treated surface, bubble formation can be observed and the leak point can be marked quickly. The frost-resistant structure helps the spray maintain its function during inspections carried out at low temperatures. Being non-flammable provides an important framework for safe use in maintenance environments.

Temperature range, certification, and technical framework
In the technical documents, the product’s temperature resistance is given as -15°C to +50°C, which is a clear limit supporting usability outdoors and in cold environments. Information on DVGW certification and suitability notes for use with gases such as oxygen provide an advantage where selection is made based on technical criteria. Physically, the product is described as “white, milky” in appearance and “almost odorless,” which is a practical detail that facilitates application control. A minimum shelf life of 24 months at room temperature is stated, making stock management easier in periodic maintenance plans.

Application method and field precautions
In application, the main method is to spray the product directly onto the connection area to be tested and observe bubble formation. Since the formulation is focused on creating bubbles even with very small leaks, results are intended to be obtained quickly. After application, thorough rinsing with water is recommended especially for plastic and copper pipes; this step helps reduce the risk of unwanted residue on the surface. Because it is a pressurized aerosol, it should be protected from direct sunlight and not exposed to temperatures above +50°C.

Compatible systems, areas of use, and key advantages
This technical spray can be used to check points such as pipes, hoses, fittings, soldered/screwed/welded joints, valves, and adapters in systems where compressed air and various gases are used. In addition to gas lines, it offers rapid screening capability in areas where leak risk is critical, such as cooling and HVAC circuits. It is stated to be safely usable with gases such as carbon dioxide, propane, butane, acetylene, oxygen, town gas/natural gas, nitrogen, N2O, and hydrofluorocarbon gases, which helps standardize different processes with a single product. Being frost-resistant and non-flammable are two standout advantages, especially for outdoor maintenance and low-temperature inspections.
