Shank Type
Shank Type couplings are typically used in medium pressure, water or liquid applications and are secured to a hose via external clamp or crimp sleeve/ferrule.  Most common configurations will be Pipe Thread (NPT/IPT), National Standard Thread (NST), and Victaulic Grooved (Vic). Hose Shanks are most versatile for attaching to hose, can be made from Brass, Aluminum, Polypropylene, Stainless Steal, or Iron. Shank types are available in both male & female types, stocked in standard sizes of ¼" up to 8".

Cam and Groove
Cam and Groove couplers and adapters are used as a means of quickly coupling small to large hose assemblies. They connect hose to hose or hose to a pipe system for the purpose of transferring liquids or dry bulk products. They are used in a wide range of applications such as petroleum handling, chemical processing, and dry bulk handling. Cam and Groove couplings are made from aluminum, brass, stainless steel, ductile iron, polypropylene, or nylon, and are stocked in standard sizes ¾” to 6”. They are available in both locking and non-locking arm designs.

Ground Joint & Air Quick Connect
Ground Joint Couplings are specially designed for high pressure air, water, and steam applications up to 600 psi depending on the size and application, stocked in standard sizes of ½" to 4".

Quick Couplings are commonly used in various applications where ease of attachment and detachment is critical.  They are available with various seals and in various styles to fit your application, stocked in standard sizes of ¼- ½".
