Manufacturing At APG

APG (formerly American Packing & Gasket) is a fabricator, manufacturer, and an expert distributor of custom sealing, industrial couplings, and plastic products. Roughly half of our Houston-based, 85,000 square feet, facility is dedicated manufacturing space filled with dozens of specialized machinery and equipment to ensure quality and consistency in our manufacturing processes.

History of APG Manufacturing

APG is a leading manufacturer and distributor of fluid sealing and conveyance products which support markets and industries globally. We began as a small fabrication shop in the Houston metropolitan area in 1943. During this time, World War II was in full stride. Many of our employees and suppliers joined the war effort leaving APG with little product to sell. This led to the company to diversify its product line and branch off into various industries. APG’s manufacturing capabilities originated with hand-cutting gaskets, packing materials, and glass products.
