Gimex Katownik 100/70 MKSC KL.2 Inox – stainless steel chimney elbow 100/70

Gimex Katownik 100/70 MKSC KL.2 Inox is a stainless steel chimney elbow engineered to connect circular flue sections with a diameter transition from 100 mm to 70 mm. Made from Inox material, this angled adapter offers corrosion resistance and dimensional stability for domestic and light-commercial venting systems. It enables a compact directional change in the flue line while adapting pipe sizes to ensure secure exhaust routing for appliances and chimneys.

Advantages

The stainless steel construction provides resistance to corrosion and high temperatures, extending service life in exhaust ducts. The tapered 100/70 geometry creates a smooth diameter transition that reduces turbulence and maintains effective draft. The component is prefabricated for straightforward installation and delivers a reliable mechanical connection between different pipe sections without need for custom welding or complex modifications.

Suitable for

• Residential chimney and flue systems where a 100 mm to 70 mm diameter reduction is required
• Connecting boilers, stoves, or water heaters to existing venting runs
• Light-commercial exhaust installations with stainless steel flue components
• Situations that require a fixed angled transition in confined installation spaces

When it may not be suitable

This chimney elbow is intended for circular flue systems with the specified 100 mm to 70 mm diameters; it will not fit systems with significantly different pipe sizes or rectangular ducts. It is optimized for gravity- or fan-assisted exhaust of typical residential appliances and may not be appropriate for specialized high-pressure industrial exhaust systems or where specific certified materials are required by local regulations.

Key specifications

• Material: stainless steel (Inox) for corrosion resistance
• Diameter transition: 100 mm to 70 mm
• Component type: angled chimney elbow / diameter reducer
• Application: exhaust/gas venting for residential and light-commercial use
• Connection: prefabricated mechanical joint for pipe coupling

How to use

Install the Gimex stainless steel elbow where a directional change and diameter reduction are required in the flue run. Ensure both mating pipe ends are clean and free of debris, then insert and align the elbow so the larger and smaller ends match the respective pipe diameters. Secure connections according to the flue system design—using approved clamps, seals or brackets as required—and verify alignment and slope for proper draft. After installation, perform a leak and draft test following appliance and local safety guidelines.

What to consider before purchase

• Verify that your flue pipe diameters are 100 mm and 70 mm to ensure compatibility
• Check local building codes and appliance manufacturer requirements for approved materials and clearances
• Confirm whether additional seals, clamps, or support brackets are needed for a compliant installation
• Assess whether the elbow angle and physical dimensions fit the available installation space

Usage recommendations

For safe and durable performance, use this Inox elbow with stainless steel flue components and follow manufacturer and local regulations for chimney installation. Regular inspection of joints and corrosion-prone areas is advisable, and any installation involving combustion appliances should be tested by a qualified technician to confirm correct draft and leak-free operation.
