Industrial Couplings

APG proudly offers cam and groove couplings in three primary grades: EVER-TITE®, TOUGH-TITE®, and U-TITE®, available in a wide variety of end style configurations.

Founded in 1937 by architect Herbert J. Krapp, the EVER-TITE Coupling Company started as an idea for a simple garden hose fitting. With the onset of World War II, EVER-TITE couplings gained traction and acceptance within the United States military because of the coupling’s ease of use compared to existing pneumatic couplings. EVER-TITE couplings are considered the first modern cam and groove quick disconnect coupling device. Herbert’s son, John, improved the design with what would become the modern-day Basic 8. This new style of coupling design integrated an internal gasket, quickly detachable couplings, utilizing engageable socket member cams, and a fluid-tight seal.
