NUAGAS Extend (Extensible Gas Hoses)

These innovative hoses offer a unique combination of flexibility and extensibility, making them the perfect solution for installations where the connection distance is variable.

Features:

  • Closed-pitch corrugated structure for exceptional flexibility.
  • Extensible design allows the hose to stretch to the required length (from 90mm up to 2000mm).
  • Undergoes a special heat treatment to relieve manufacturing stress, which increases corrosion resistance and enhances service life.
  • Available with a non-flammable Polyolefin shrink cover for added protection against chemical and mechanical damage.
  • Applications:
  • Connecting cookers, stoves, fireplaces, barbecues, combi-boilers, and heaters.
  • Benefits:
  • Minimizes installation time and cost by adapting to various connection distances.
  • Can be bent to a tight radius without reducing the internal flow area.
  • Guarantees a high degree of safety and reliability.

NUAGAS Flex (Non-Extensible Gas Hoses)

A dependable and straightforward solution for standard gas appliance connections where extensibility is not required.

Features:

  • Flexible body with secure, factory-tested screwed fittings.
  • Applications:
  • General natural gas connections in household and commercial settings.
  • Benefits:
  • Cost-effective, quick, and easy installation.
  • Durable design ensures a long and trouble-free working life.

System & Installation Gas Hoses

This range covers specialized hoses for building infrastructure, system components, and industrial gas applications.

NUAGAS Pipe (CSST System)

Corrugated Stainless Steel Tubing (CSST) represents a modern, innovative approach to indoor gas installations, offering a flexible and efficient alternative to traditional rigid black iron pipe.

Features:

  • A semi-rigid, corrugated stainless steel hose system.
  • Connects easily to various thread types using high-quality mechanical fittings.
  • Available in standard sizes DN15, DN20, DN25, and DN32.
  • Applications:
  • Complete indoor natural gas and LPG installations for residential and commercial buildings.

Benefits:

  • Significantly saves on assembly time and labor costs.
  • Much lighter and easier to handle and route than traditional pipe.
  • Allows for rapid, safe, and efficient project implementation.

Component Connection Hoses

We offer a range of flexible hoses for connecting specific gas system components, all designed for easy installation and reliable service.

  • Regulator Connection Hoses: For domestic, commercial, and system regulator connections.

Seismic & Expansion Hoses for Gas Lines

These assemblies are engineered to protect gas piping systems from structural movement and mechanical stress.

Features:

  • Flexible design absorbs deflection, thermal expansion, vibration, and seismic movement.
  • Applications:
  • Used at building dilatation points and across seismic gaps to protect the integrity of the gas line.
  • Benefits:
  • Safeguards the gas system from mechanical stress and movement.
  • Reduces vibration transfer between building sections.

Hoses for Technical and Medical Gases

High-pressure hose assemblies designed for the safe, pure transfer of industrial, cryogenic, and medical gases.

Features:
