APG: Pioneering American Excellence in Coupling Solutions Since 1933

July 7, 2025

Behind the Coupling: The Legacy of EVER-TITE® and APG’s American-Made Excellence

For over 90 years, American Packing & Gasket (APG) has stood at the forefront of coupling innovation, setting industry standards with its commitment to quality, performance, and American manufacturing. From the groundbreaking EVER-TITE® cam and groove coupling to a diverse portfolio of industrial solutions, APG's legacy is one of resilience, ingenuity, and unwavering dedication to excellence.

A Legacy Forged in Innovation

The story begins in 1933 when John T. Krapp introduced the EVER-TITE® coupling, revolutionizing the way industries approached quick-connect solutions. Its unique internal locking mechanism ensured superior resistance to loosening, addressing a common challenge with traditional fasteners. This innovation quickly gained traction across sectors like heavy machinery, transportation, and oil drilling, earning a reputation for reliability and durability.

During World War II, the U.S. military recognized the strategic advantage of EVER-TITE® couplings. Their ease of use and robust performance led to widespread adoption. To meet the surging demand, the U.S. government requested the release of the EVER-TITE® patent, allowing other manufacturers to produce these vital components for the war effort. This move not only underscored the coupling's significance but also cemented its place in industrial history.

APG’s Origins and Growth

Founded in Houston in 1943, APG began as a modest fabrication shop supplying soft gaskets to Southeast Texas. As global demands shifted, especially during wartime, APG diversified its offerings, expanding into various industries and solidifying its reputation as a reliable partner. In 2003, APG acquired EVER-TITE®, integrating its innovative couplings into APG's extensive product lineup.

Today, APG ensures every coupling meets rigorous quality standards – delivering the reliable performance our customers depend on.
