SET OF 3 HOSES 90CM - 336RYB-S

Set of 3 Hoses 90cm - 336RYB-S (Reference: 080503) represents the essential professional solution for all your air conditioning and refrigeration work. These high-performance hoses with standardized Red-Yellow-Blue colors facilitate circuit identification and guarantee fast and secure intervention on air conditioning systems with R134a refrigerant gas.

Professional applications and usage sectors

These hoses are specially designed to meet the requirements of refrigeration technicians, automotive mechanics and industrial air conditioning professionals. The standardized color code facilitates circuit identification: red for high pressure, blue for low pressure and yellow for recovery or service. This colorimetric organization respects international standards and prevents handling errors.

Application sectors include automotive air conditioning, commercial refrigeration systems, residential heat pumps and industrial air conditioning installations. The 90cm length offers optimal flexibility to access hard-to-reach components while maintaining a safe distance from rotating engine elements.

Technical construction and high-performance materials

Each hose is manufactured with a synthetic rubber inner tube specially formulated to resist R134a refrigerant gases and compressor oils. The high-strength textile braid reinforcement ensures exceptional mechanical strength against high service pressures, typically up to 35 bars for high-pressure applications.

The colored outer casing is not just aesthetic: it offers UV protection and remarkable abrasion resistance. The 1/4 female fittings are precision-machined to guarantee perfect sealing and quick connection with measuring and service equipment. The anticorrosion surface treatment of the fittings ensures maximum durability even in aggressive environments.

Installation and optimal use

Installing these hoses requires some essential precautions to guarantee safety and performance. Before each use, visually check the condition of the hoses: absence of cuts, cracks or abnormal deformations. The fittings must be cleaned and free of foreign bodies to ensure a tight connection.

During connection, tighten firmly but without excess to avoid damaging the seals. The 90cm length allows maintaining sufficient distance from hot engine elements and avoids excessive mechanical stress. After use, completely purge the hoses and store them in a dry place, away from direct light and extreme temperatures.

For maintenance, regular cleaning with mild detergent and rinsing with clean water is sufficient. Avoid aggressive solvents that could alter the rubber properties. Periodic leak-tightness control with an electronic leak detector is recommended for critical applications.
