Camlock Couplings

Product Overview

Camlock couplings, also known as cam and groove fittings, are high-efficiency quick-connect connectors used to join hoses and pipes without the need for tools, threads, or complex bolting. The system operates on a simple manual lever mechanism: a male 'adapter' is inserted into a female 'coupler', and two cam arms on the sides of the coupler are pressed down simultaneously. This action pulls the adapter tight against an internal gasket, creating a leak-proof, vibration-resistant seal in seconds. Because they do not rely on threads that can be damaged by dirt or grime, they are exceptionally durable for use in 'dirty' environments like construction sites or oil fields.

These couplings are classified into standard types (A through F) based on their end connections, such as threaded ends or hose barbs, allowing them to integrate into virtually any piping architecture. For instance, Type C features a hose shank for direct attachment to flexible lines, while Type A provides a male adapter with a female thread for stationary equipment. To ensure safety under pressure, many modern camlocks include locking pins or 'self-locking' handles that prevent the arms from accidentally opening due to surge pressures or dragging along the ground.

Material selection for camlock couplings is dictated by the specific fluid being transferred and the operating environment. Aluminum is the go-to for water and petroleum due to its lightweight and cost-effective nature, whereas Stainless Steel (316) is mandatory for hygienic food processing or corrosive chemical transfer. For agricultural irrigation and fertilizer handling, Polypropylene or Nylon variants offer excellent chemical resistance at a lower price point. It is important to note that while they are incredibly versatile, camlock couplings are typically rated for low to medium pressures and are not suitable for steam applications, as the sudden release of high-temperature vapor could be catastrophic.
