Cam & Groove Couplings

Product catalog summary
Cam & Groove General Information
This section provides an overview of Dixon's Cam & Groove couplings and accessories, detailing various types of adapters and couplers such as Type A, B, C, D, E, F, DC, and DP. It emphasizes safety by advising against using dust caps and plugs in pressure applications and notes that these couplings are unsuitable for compressed air or steam service.
Specifications
Dixon's Cam & Groove couplers and adapters are designed to interchange with products conforming to Commercial Item Description A-A-59326D. There are no standards for 1/2", 5", and 8" fittings, which may not interchange with other manufacturers' products. Pressure ratings for various sizes are provided, with recommendations for ambient temperature use and guidance to consult Dixon for elevated temperatures or unusual conditions.
Features of Dixon Cam & Groove Styles
The brochure highlights precision machining and durable construction, including stainless steel cam arm pins, a gasket recess for proper placement, and a long shank design to prevent hose damage. The Boss-Lock and EZ Boss-Lock styles offer additional safety features like locking mechanisms and guaranteed stainless steel cam arms.
Vent-Lock® Safety and EZLink® Armless Features
Vent-Lock® couplings allow for the safe release of static pressure, protecting operators from hazardous fluids. They are not interchangeable with standard cam & groove products. EZLink® armless couplers provide a push-to-connect feature, ensuring a reliable connection that cannot be disconnected under pressure. The Venting EZ Boss-Lock system offers a unique method for safely venting systems under pressure, enhancing user safety and ergonomics.
Crimp Fittings
The document lists several styles of crimp fittings, including Dixon type C couplers, EZ Boss-Lock type C couplers, and Global type C couplers. Sizes range from 1" to 6", and materials include 356T6 aluminum, brass, 316 stainless steel, and unplated ductile iron.
Sleeves and Ferrules
Available in sizes from 1" to 6", these components are made from carbon steel, 304 stainless steel, and aluminum. It is crucial to use crimp style shanks with corresponding sleeves and ferrules for safety reasons.
Swivel Couplings
These couplings feature a live swivel capable of 360-degree rotation under pressure and include nitrile rubber X-ring seals. They are available in 356T6 aluminum and 316 stainless steel.
Venting EZ Boss-Lock Cam & Groove
Designed for safe disconnection during fluid and solid transfer, these couplings feature a venting system that retains the coupling and allows pressure to vent off safely. They are made from 316 stainless steel and 356T6 aluminum.
EZLink® Armless Couplers
These automatic couplers are push-to-connect and provide a reliable connection for fuel transfer. They are compatible with standard cam & groove adapters and come with a lifetime warranty on stainless steel tabs. The maximum working pressure varies by size and attachment method.
Vent-Lock® Safety Cam & Groove Couplings
These couplings allow for the safe release of static pressure during disconnection. They are rated to 250 PSI and are available in 316 stainless steel and aluminum. They feature safety orange cam arms and require Dixon L-style fittings for compatibility.
Specifications and Safety
The document emphasizes the importance of using compatible components and provides detailed specifications for pressure ratings and temperature ranges. It also highlights the need for consulting Dixon for specific material availability and unusual operating conditions.
Product Types
Includes Vent-Lock® Type E Adapters, Vent-Lock® Safety Cam & Groove Type DC Dust Caps, EZ Boss-Lock Type H Dust Caps, and Type A, B, C Couplers.
Additional Notes
Replacement inserts and other materials are available upon consultation with Dixon. Specific instructions for use with Dixon Vent-Lock and EZ Boss-Lock couplers are provided.
Materials and Part Numbers
The document lists part numbers for different sizes and materials, including aluminum, brass, and stainless steel. It highlights that no standard exists for certain sizes, which may not interchange with other manufacturers' products.
Pressure Ratings
The pressure rating for adapters is based on the seal of the mating part. Maximum operating pressures are specified for different sizes and materials, with recommendations based on the use of mating Dixon fittings at an ambient temperature of 70°F (21°C).
Additional Components
The document also covers handles for couplers, safety clips, and adapters with ANSI and TTMA flanges. It notes that handle assemblies are specific to global Dixon parts and do not interchange with other manufacturers' products.
Polypropylene Cam & Groove
This section details the specifications for polypropylene cam & groove fittings, including maximum operating pressures and compatibility notes. It emphasizes that these should not be mixed with metal fittings and are not recommended for use with PTFE gaskets.
Warranty and Liability
Dixon warrants products to be free from defects in material and workmanship for one year from the date of shipment. The warranty does not apply to products not manufactured by Dixon, products subject to abuse, or products altered by others. Dixon disclaims all other warranties, express or implied, including merchantability or fitness for a particular purpose.
Safety and Compliance
Dixon products are not recommended for potable water service unless specifically approved. Products contain lead, a chemical known to cause cancer and birth defects.

Size represents the coupler or adapter and hose or pipe end (i.e. 200 = 2"). If the coupling is a jump size, the coupler or adapter is the first size (i.e. 4030-C is 4" coupler to 3" hose shank). 1. To make connection, slide the adapter into the coupler and, with normal hand pressure, press the cam levers down. 2. Uncoupling is as quick and simple as coupling. Just lift the cam levers and remove the adapter. • Dixon, Boss-Lock, and EZ Boss-Lock cam & groove couplers and adapters are produced to interchange with all product produced to Commercial Item Description A-A-59326D. • No standard exists...
