Marli was founded in 1980 in rented warehouse space in Johnson City, NY.  The original line was traditional engine fasteners and rocker arm components.  Oil drain plugs and gaskets were added in 1983 and engine head bolts in 1984.

All lines continue to expand even today, and Marli added rubber expandable nuts in 2006. In December 2010 Marli acquired MasterPlug®, a specialty line of rubber expandable nuts with a wide variety of industrial applications.

In 1993 a warehouse was purchase in Binghamton, followed by a building expansion in 1994, and a further expansion in 2008.  ISO 9001:2000 certification was obtained in 2003, with an update to ISO 9001:2008 in 2009.

Today Marli is looking to continue growing existing lines to offer complete coverage and expand to other parts where exemplary service can be provided.
