Flexible corrugated metal connection hose Perfexim PHA-250/2 DN12 Typ1 WW L-750 for water installations

Perfexim PHA-250/2 DN12 Typ1 WW L-750 is a flexible corrugated metal connection hose designed for water installations. The hose features a corrugated internal tube with an external metal braid that provides flexibility and mechanical protection. It is intended for use where a pressure-resistant, adaptable connection is required between water supply lines and fixtures or appliances. The construction complies with industry safety standards for flexible water connectors.

Advantages

The corrugated design combined with a metal braid ensures both flexibility and resistance to pressure and mechanical damage while maintaining a compact profile. Its DN12 nominal diameter and 750 mm length allow it to bridge moderate distances without additional fittings. The materials used provide reliable performance in typical hot and cold water systems and reduce the risk of kinking compared to rigid pipes.

Suitable for

• Connecting faucets, mixers and sanitary fixtures to water supply lines
• Linking household appliances such as dishwashers and washing machines to inlet valves
• Temporary or permanent connections in tight installations requiring flexible routing

Key specifications

• Nominal diameter: DN12
• Length: 750 mm
• Construction: corrugated internal hose with external metal braid
• Application: potable water systems, hot and cold water
• Type designation: Typ1 WW (suitable for water)

How to use

Ensure the water supply is turned off and the system is depressurized before installation. Verify compatibility of connection ends with the fixture and supply fittings. Fit the hose between the supply valve and the appliance or fixture, making sure the hose is not twisted or overly bent; avoid sharp bends and compression at the connection points. Tighten fittings to the recommended torque for the mating threads to ensure a leak-free seal. After installation, slowly restore water pressure and inspect all joints for leaks.

Usage recommendations

Use the hose within its intended temperature and pressure range, avoid exposure to corrosive chemicals or direct sunlight for extended periods, and periodically inspect the braid and fittings for signs of wear or damage. Replace the hose immediately if any visible deterioration or persistent leakage occurs.
