Chimney liner WADEX 120 mm diameter, length 0.5 m

Chimney liner WADEX 120 mm diameter, length 0.5 m is a stainless-steel flue liner section designed to provide a smooth, heat-resistant passage for exhaust gases from heating appliances to the chimney. This 0.5 m segment fits into a modular system of liners and is intended for repair, replacement or extension of existing chimney flues where a 120 mm internal diameter is required. The product is compatible with appliances that need a 120 mm liner connection and is suitable for installations that require corrosion resistance and stable geometry under elevated temperatures.

Advantages

The liner offers consistent internal diameter and a smooth inner surface to support efficient flue gas flow and reduce soot accumulation. Constructed from heat-resistant materials, it is designed to withstand the thermal conditions typical of solid-fuel and gas-fired appliances. Its modular 0.5 m length allows flexible configuration when assembling a chimney liner system or making targeted repairs without replacing longer sections.

Suitable for

• Repairing or extending existing chimney flues with a required 120 mm internal diameter
• Connecting compatible solid-fuel boilers, stoves or fireplaces to a chimney
• Connecting compatible gas-fired appliances that specify a 120 mm liner
• Creating or rebuilding a lined chimney system in residential installations

Key specifications

• Internal diameter: 120 mm
• Length: 0.5 m
• Material: heat-resistant stainless steel (smooth inner surface)
• Construction: modular liner section for insertion into chimney flue
• Suitable for use with solid-fuel and gas-fired appliances that accept a 120 mm liner

How to use

Measure the existing flue and confirm that a 120 mm internal diameter liner is appropriate for the appliance and chimney conditions. Insert the 0.5 m liner section into the flue or adjoining liner pieces, ensuring proper alignment and secure jointing according to the chimney liner system instructions. Seal and support connections as required by local building codes and manufacturer guidance, and ensure correct chimney draft before regular use. Installation should follow applicable safety standards and, where required, be performed or inspected by a qualified technician.

Usage recommendations

Use this 0.5 m liner segment as part of a continuous, properly supported liner system; avoid leaving unsupported or unsealed joints. Regular inspection and cleaning of the flue are recommended to maintain safe operation and efficient exhaust flow. Confirm appliance compatibility and local regulatory requirements prior to installation.
