Elkhart Products Corporation (EPC) is located in Elkhart, Indiana – the heart of the Midwest. From its start in 1940 as a small manufacturer of screw machine products, EPC has built a reputation for quality products and quality personnel. As the company began to expand in the early 1950s and became a fabricator of various copper and aluminum tubular components, it also became known for its innovation and service. Over the last five years, EPC has branched into engineered fittings. EPC engineered push-fit fitting brands include TECTITE™ and CopperLOC™. In 2011, we introduced APOLLOPRESS® press-fit fittings and valves. APOLLOPRESS® products are manufactured in the USA by EPC and Apollo Valves. Together, we bring you the most extensive line of quality American Made press-fit products.
