A TRADITION OF EXCELLENCE

For over 50 years, Security Chimneys has been an innovator in the venting field and a market leader in North America. Instrumental in the company’s growth has been an ongoing focus on product improvement and the introduction of new, innovative products. This drive for excellence has given rise to the Tubinox venting system, a line of high-quality products that deliver optimal performance.

FOR YOUR SAFETY

Time and wear can crack clay liners. Under these conditions, your liner can quickly become a nest for creosote deposits. Should this be the case with your masonry chimney, it would be wise, for safety reasons, to consider the advantages of a TUBINOX stainless steel liner. The accumulation of creosote inside a chimney can become dangerous. As it is inflammable, creosote is the cause of chimney fires which can spread to become a real danger. The stainless steel liner impedes the adhesion of creosote.

FOR GREAT PERFORMANCE

Controlled combustion stoves are designed accordingly to highly efficient heat transfer and combustion technologies. Their rate of performance increases when they are installed with a chimney of suitable diameter. Clay liners are often too large. Consequently, they remain too cold and do not allow gas to be completely consumed, a situation that leads to gas condensation, thus the formation of creosote.

As some other reviews have said the plastic does feel a little fragile, but I've never cracked one. I have three for my 1900 watt system and they have worked excellent for my application.

I'm very happy with these I normally buy Knukonceptz they have great product and always have one of their fuses. But I needed to pinch pennies more so in decided to buy these. These are really really solid. Some said the plastic was junk but I think they must not know what they're doing bc they snapped to place properly. They are super solid my 0 gauge fit in it like a glove as should, screwed in well. And is doing its job. Would buy again for sure!
