NMC hose set DN25 with 1"/1" fittings, UV-insulated 9 mm, length 1.50 m, pack of 2

Set of two NMC hose assemblies designed for DN25 plumbing and heating connections. Each flexible hose is 1.50 m long and terminated with 1" threaded fittings at both ends. The hoses are fitted with 9 mm UV-resistant insulation to reduce heat loss and protect the exterior from solar degradation. These hoses provide a flexible, insulated link for pumps, boilers and piping sections where DN25 connections are required.

Advantages

The NMC hose set combines flexibility and thermal protection in a compact assembly. UV-insulated jackets help maintain fluid temperature and extend service life in outdoor or sun-exposed installations. Standard 1"/1" threaded fittings permit straightforward connection to common DN25 components without special adapters, while the 1.50 m length offers reach for typical pump and boiler setups. Supplied as a pack of two, the set supports paired supply and return line installations.

Suitable for

• Connecting circulator pumps to DN25 piping or manifolds
• Linking boilers, water heaters or heat exchangers to DN25 lines
• Replacing rigid sections where flexibility is required for alignment or vibration isolation
• Outdoor or sun-exposed runs where UV resistance improves longevity

Key specifications

• Connection size: DN25 with 1" threaded fittings at both ends
• Hose length: 1.50 m per hose
• Insulation thickness: 9 mm UV-resistant jacket
• Pack quantity: 2 hoses
• Material type: flexible hose with protective insulation (manufacturer standard)

How to use

Verify that system shutdown and pressure relief procedures are followed before installation. Select the correct orientation and thread the 1" fittings onto compatible DN25 male threads, ensuring proper sealing with an appropriate sealing method (thread seal tape or approved joint compound) according to local codes. Tighten fittings to a recommended torque consistent with the connected component specifications to avoid overtightening. Route hoses to avoid sharp bends, kinking, or contact with hot surfaces that could damage the jacket. After installation, perform a leak test and inspect the insulation for correct seating and continuity.

Usage recommendations

Use the hoses as paired supply and return connections for small to medium hydronic circuits. For long-term outdoor exposure, periodically inspect the UV-insulated jacket for signs of wear or ultraviolet aging and replace if degradation is observed. Do not exceed the pressure and temperature limits specified by the system components to which the hoses are connected.
