Stop Leaks EXTERNAL

ERRECOM Stop Leaks EXTERNAL (Reference: 081110) represents ERRECOM's innovation in the field of emergency repair for air conditioning and refrigeration systems. This professional product offers a high-performance external sealing solution, specifically designed for rapid on-site interventions without disassembling components.

Applications and professional benefits

EXTERNAL is aimed at refrigeration technicians, professional HVAC engineers and informed end-users dealing with leaks in their installations. This external leak stopper excels at repairing leaks up to 5mm in diameter on condensers, evaporators, rigid and flexible pipework.

Ideal for emergency interventions on automotive air conditioning systems, residential heat pumps, commercial cold rooms and industrial systems. External application eliminates the risk of contaminating the refrigerant circuit while ensuring lasting sealing performance.

Particularly effective on connection joints, porous welds, condenser micro-cracks and sealing defects in aged rubber components.

Technology and technical compatibility

EXTERNAL's advanced formulation guarantees exceptional resistance to synthetic and mineral lubricants used in refrigeration compressors. Compatible with all refrigerant gases: R134A, R410A, R32, R290, R404A, R407C and new eco-friendly refrigerants.

Its thermal resistance allows it to operate across extreme temperature ranges, from cryogenic applications to high-temperature condensers. The product retains its sealing properties even under significant vibratory stress.

EXTERNAL adheres perfectly to metal surfaces (copper, aluminium, stainless steel) and elastomers (EPDM, neoprene, butyl) without altering their mechanical properties.

Application method and implementation

Applying EXTERNAL requires careful surface preparation: cleaning, degreasing and complete drying of the leak area. Switch off the system and wait for pressure to stabilise.

Apply the product in uniform layers over and around the leak, ensuring a minimum overlap of 10mm. Polymerisation time varies depending on ambient humidity and temperature (15 to 45 minutes).

For larger leaks (3-5mm), apply a first coat, allow to dry for 20 minutes, then apply a second cross coat. Carry out a progressive leak test before full recommissioning.

The repaired area can be repainted after complete polymerisation for aesthetic integration.

Expert tips and optimisation

To maximise EXTERNAL's effectiveness, combine its use with ERRECOM internal additives during full service procedures. This bi-directional approach ensures optimal protection against re-leaks.

Store the product in a temperate environment (5-25°C) away from moisture to preserve its qualities. Shake vigorously before each use after prolonged storage.

Avoid common mistakes: applying to wet surfaces, under-dosing on large leaks, re-pressurising too quickly. For critical systems, plan the intervention during periods of low thermal load.
