Flexible metal connection hose Perfexim PHA-250/2 DN12 Typ1 WW L-2000 — corrugated EN14800

Perfexim PHA-250/2 DN12 Typ1 WW L-2000 is a corrugated flexible metal connection hose designed for domestic and light commercial water installations. With a nominal diameter of DN12 and an overall length of 2000 mm, this hose complies with EN14800 and is intended for hot water supply (Typ1 WW). Its metal corrugated construction provides flexibility for routing between fixed pipework and fixtures while maintaining pressure resistance and leak-safe performance.

Advantages

The corrugated stainless-steel construction combines flexibility with mechanical strength, allowing the hose to bend around obstacles without kinking. Compliance with EN14800 ensures compatibility with standard plumbing systems and recognised safety requirements for flexible connectors. The 2 m length reduces the need for additional fittings or extensions and simplifies installation in locations where a longer reach is required. The hose’s internal design and materials are suitable for use with potable hot water systems.

Suitable for

• Connecting hot water fixtures such as faucets, boilers, and water heaters to supply lines
• Extending supply lines where a 2 m flexible connection is required
• Installations in bathrooms, kitchens, utility rooms, and light commercial settings

Key specifications

• Nominal diameter: DN12
• Nominal length: 2000 mm
• Type: Typ1 WW (hot water)
• Standard: EN14800
• Construction: corrugated metal hose for flexible connections

How to use

Before installation, verify that the hose dimensions and type match the system requirements and that operating temperatures and pressures are within the hose’s rated limits for hot water use. Ensure thread types and connection ends on fixtures or adapters are compatible. Hand-tighten the fittings first, then use appropriate tools to secure connections to the manufacturer’s recommended torque to avoid over-tightening. Route the hose without sharp bends or contact with abrasive surfaces and avoid twisting during installation. After installation, pressurise the system and inspect all connections for leaks.

Usage recommendations

For durable performance, schedule periodic visual inspections for abrasion, corrosion, or deformation, and replace the hose if any damage is observed. Use suitable sealing materials on threaded joints only where required and compatible with potable water systems. Keep the hose accessible for maintenance and avoid permanent compression or kinking.
