A legacy in Producing Exhaust Flex Pipe and Flexible Metal Tubing.

We have been manufacturing quality flex pipe since 1956, in fact, we patented our unique tooling that ensures the tightness of the wrap. This patented roller allows us to guarantee the pipe you buy from us does not unravel when cutting. (handling instruction link). Before our patented tooling we couldn’t make the claim that our pipe would not unravel. But, for more than 40 years we have led the industry in flex pipe, in fact, a common comment from customers has been,

“your HQ Flexatube brand flex pipe does not unravel!”

Used in a Variety of Applications

Flex pipe is used for a variety of applications from heavy-duty truck and commercial vehicles to industrial & mining ventilation to agricultural applications. The leak-resistant and tough nature of the pipe make it appropriate for the toughest environments.

Variety of Steel Options all from the USA.

Our flex pipe is available in galvanized, stainless steel 409 (product link) and the premium no rust option stainless steel 304 (product link). We buy the highest grade steel available from our USA and Canadian providers.

Galvanized Most Affordable Option

Galvanized exhaust flex pipe is our most affordable option and comes in a variety of weights including light weight, standard weight, and heavyweight (gauge or thickness). It’s common for the standard weight (0.018-0.020″) to be used in most applications but those in the toughest use cases often prefer the heavyweight gauge, it comes in a hefty 0.023-0.025 thickness.
