Can FW-1661 leak detector be safely used on heated exhaust pipes and maintain effectiveness across its -15Â°C to +70Â°C operating range?

Yes. FW-1661 leak detector can be safely used on heated exhaust pipes and will remain effective within its specified operating range of â15Â°C to +70Â°C. The product description explicitly states it is suitable for exhaust pipes and forms an active, bubble-producing film to indicate leaks. Its special formulation allows adhesion on vertical surfaces and piping, and because it is non-corrosive and non-flammable, it is appropriate for use on metal (steel, copper) and plastic exhaust components so long as the pipe temperature stays within the stated â15Â°C to +70Â°C range. Precautions: avoid applying to surfaces hotter than +70Â°C, ensure proper ventilation when working on hot exhaust systems, and allow the detector to cool into its operating range if pipes exceed the limit before relying on consistent performance.

Is FW-1661 leak detector safe for use on painted or coated pipes without damaging the surface?

Yes. FW-1661 leak detector is safe for use on painted or coated pipes. It is non-corrosive and non-flammable, formulated for use on steel, copper and plastics, and leaves an active film that reveals leaks by bubbling without attacking surfaces. Its special ingredients allow application on vertical surfaces and exhaust pipes, and it works between â15Â°C and +70Â°C. As with any product, test a small inconspicuous area first if the coating is delicate or of unknown composition.

Can FW-1661 leak detector be used on pressurized gas cylinders and fittings without impairing seals?

Yes. FW-1661 leak detector in spray form is formulated to be non-corrosive and non-flammable and is specifically designed for use on gas lines, compressed air and other gases, including pipe joints, valves and fittings. It forms a stable active film that reveals leaks by producing bubbles and works on steel, copper and plastic surfaces (including vertical and exhaust piping). Within its operating temperature range (â15Â°C to +70Â°C) FW-1661 can be used on pressurized gas cylinders and fittings without impairing seals, provided the seals and cylinder materials are compatible with typical non-corrosive detector fluids and the system is depressurized or handled per safety procedures when applying spray near high pressures or critical threads. If in doubt, test a small inconspicuous area or consult the cylinder/seal manufacturer for specific chemical compatibility.
