Atcoflex, Inc. was formed in 1978 as a spin off of Atco Rubber Products, Inc. Atco Rubber Products began making specialized hose in 1961 and became one of the largest suppliers of HVAC and clothes dryer vent hose.

In 1978 Atcoflex, Inc. began making air duct for the automotive industry, being one of the first to incorporate thermoplastic rubber for such purposes. The hose was originally  designed to replace friction tape hose, which had been widely used by the automotive industry.

Atcoflex has designed and constructed it's own unique machinery for the manufacture of flexible ducting and has also supplied small assemblies to the big three automakers. Due to this in-house machinery construction, coupled with a large tooling inventory, Atcoflex has been able to quickly design and build specialty hoses or make very fast changes to specifications.

With quality as a watch-word, Atcoflex began using Statistical Process Control in the early 1980's and was one of the first company laboratories to be GP-10 Approved by General
Motors.

In 1991 Atcoflex earned Ford's Q1 Award and Chrysler's QE Award in 1992. In 1994 Atcoflex was one of only three companies to be given the Partners in Excellence Award by United Technologies Automotive. In 1997 Atcoflex, Inc. achieved registration to QS-9000 and ISO-9002 and is ISO-14001 compliant. In November, 2004, Atcoflex, Inc. achieved registration to
ISO/TS 16949..
