Flexible hose set Famas DN20 with NO1/NO1 fittings, length 500 mm, pack of 2

Pack of two Famas flexible hoses DN20 with NO1/NO1 fittings, each 500 mm long, designed for plumbing and heating installations. These ready-made connectors are intended to link valves, appliances and pipework where a DN20 nominal diameter and standard NO1 threaded fittings are required. The hoses are supplied as a pair to cover parallel connections or for use as spare components during maintenance.

Advantages

The flexible hose set offers a compact, preassembled solution that reduces installation time compared with cutting and fitting rigid pipe sections. With standard NO1 end fittings and a nominal diameter DN20, the hoses provide consistent flow capacity for domestic and commercial systems. The 500 mm length balances reach and flexibility, allowing for alignment adjustments without stressing connections. Supplied as a pack of two, the set supports dual connections or replacement needs.

Suitable for

• Connecting boilers, water heaters or pumps to existing pipework
• Linking shut-off valves to appliances or radiators
• Temporary or permanent connections in residential plumbing
• Service and maintenance replacements for DN20 connections

Key specifications

• Nominal diameter: DN20
• End fittings: NO1 on both ends
• Length: 500 mm per hose
• Quantity: pack of 2 hoses
• Intended use: fluid connections for plumbing and heating systems

How to use

Ensure the system is depressurized and drained before disconnecting existing connections. Fit each hose by hand-threading the NO1 fittings onto the corresponding male or female threads, then tighten to manufacturer-recommended torque using appropriate wrenches. Position hoses to avoid sharp bends or kinks and verify that the length allows comfortable alignment between connection points. After installation, restore system pressure and inspect all joints for leaks. If any leakage is detected, depressurize again and retighten fittings or replace the hose if necessary.

Usage recommendations

Use the hoses only within the operating temperature and pressure limits of the overall installation; consult system specifications for compatibility with water, glycol mixtures or other fluids. Replace hoses showing visible wear, corrosion, or damage and follow local plumbing codes for installation and periodic inspection intervals.
