Duro-Line Steel Line Sets Change the HVAC Game

Why SolderWeld and Lance Are All In on Duro-Line Steel Linesets

If you’ve been in the field long for any length of time, you know that not all line sets are created equal. As supporters of the tradespeople in the field, we are always excited when there is an innovation that lights up the the scene, a game changer if you will.  We always keep our eyes out for solutions that perform better, last longer, and make your work easier. That’s exactly why SolderWeld is 100% behind Duro-Line Steel Linesets.

This isn’t a gimmick, it's the next level, and here’s why:

Proudly American Made with a 20-Year Warranty

When you stand behind quality, you stand behind your country and Duro-Line delivers both. These steel line sets are manufactured right here in the USA and are backed by a 20-year warranty, proving how confident Duro-Line is in their durability and performance.

This isn’t imported mystery metal. It’s engineered, tested, and built with the end-user in mind.  This is not a new concept, just new to HVAC.  Low Carbon steel line sets have been used in the automotives and refrigeration industries for years.  

No New Tools Required

You don’t need to reinvent your toolbox. Duro-Line mimics the dimensions and feel of copper, meaning you can swage, flare, and bend with the tools you already trust. No extra spend. No new learning curve. Just grab it and go.

And it bends and brazes like a dream.

More Precision, More Rigidity, Less Hassle

Duro-Line’s steel tubing is more precision round than many copper or aluminum alternatives. That means your flares are tighter and your installs are cleaner.

The rigid structure gives you better bending control, reducing kinks, crimps, and frustrations. Whether you’re doing long runs or tight turns, Duro-Line holds its shape and finishes clean.

Corrosion Resistant & Built for the Long Haul

Unlike copper, which can pit, or aluminum, which can fatigue over time, Duro-Line is engineered to resist corrosion, even in harsh environments. That means fewer callbacks, fewer replacements, and more time doing the work that pays.

Built for the Trades. Backed by SolderWeld.

We don’t put our name behind products easily. At SolderWeld, we field-test everything before we stand behind it. We have been there for the real world tests.  We've seen it bent, brazed, pressure tested and we've been there for the follow ups.  We have seen these products get put through the ringer and we remain nothing less than impressed.

Duro-Line Steel Line Sets passed with flying colors.

“Duro-Line is exactly what the trade has been asking for.  No gimmicks, no fluff. Just straight-up performance with no compromises.”
– Lance Robinson, CEO, SolderWeld
