Tough, Accurate Heated Lines

At Atmo-Seal, Inc., we know that heated hoses and heated sample lines are stretched, dropped and slammed every day.  Our Enduro-Flex Heated Emissions Sample Lines are designed for their environment: Dynamometer Labs and Test Cells, On-Road Certification, CEMS Sites, etc.,

No one in the industry can touch our accuracy of temperature. Independent studies have shown that the temperature resolution of an ASE heated hose is unmatched by ANY in the industry.

Our heated hoses and heated lines all feature light-weight end treatments made from either tough, high-temperature phenolics or plated steel, all with operational temperatures in excess of 200 C. There are no epoxy-potted ends- which break, crack and burn; no cumbersome heat shrink ends - which melt and become brittle in time; just a high-quality end - is suitable for ovens or other high-temp situation - on every hose.

We offer a choice of sample line exteriors to make your heated sample line  suitable for even the most extreme environments. We offer exteriors that are suited for direct burial, outdoor use, hazardous locations, cold rooms, the desert and the tundra, or just being pulled through your factory or lab.  Wherever you need a tough, accurate heated sample line, we can provide it.

Another advantage of our heated hoses and heated sample lines is that they are designed to be easily repaired! In most cases, our heated lines may be repaired easily in the field by our staff or yours!  Our lines feature user-replaceable sample tubes, end cap and end fittings. Our heated hoses carry a full 18 month limited warranty, too!

And, of course, your hoses will have the Most Accurate and Verifiable Temperature Resolutions in the Industry! With  25 years of Precision Heated Hose Design and Emissions Sampling Experience, our staff has the technical ability to meet all of your specifications.
