Aerofit Products was founded in 1969 by Robert F. Peterjohn and began production in a 5,000 square feet (460 square meter) building. He started with a single Clausing engine lathe but soon added turret lathes, mills and other equipment. The first major product development was a metal port seal fitting used on the DC-10 aircraft. Aerofit qualified and received their first long term contract in 1969.

In March 1972 APT laboratories was established as a hydro-mechanical testing laboratory and in 1976 Aerofit Products received its first Boeing approval. In 1999 Aerofit acquired the Shape Memory Alloy (SMA) fitting system, which includes the copyright names CryoFit®, CryoFlare®, and CryoLive®. The Aerofit site grew into six buildings totaling 47,000 square feet (4,400 square meters).

Aerofit Products and APT remained in the Peterjohn family until 2004 when they were sold to Jordan Law and Dave Werner. In 2005 the new company was renamed Aerofit, Inc. and moved into a 67,000 square feet (6,200 square meters) modern building in Fullerton, CA.

In 2013, Aerofit, LLC became part of Consolidated Aerospace Manufacturing (CAM). Today the company operates from two buildings totaling 92,000 square feet (8,500 square meters) and is a world-class provider of specialty components and related services.
