DIXON VALVE & COUPLING
Frequently asked questions
Common questions about DIXON VALVE & COUPLING from 3G Electric.
What materials are available for Dixon Valve & Coupling cam and groove fittings?
Dixon Valve & Coupling cam and groove fittings are manufactured in forged brass, 316 stainless steel, and steel. Forged brass fittings are suitable for applications requiring corrosion resistance in non-aggressive environments, while 316 stainless steel provides higher corrosion resistance for chemical and marine applications. Steel fittings are typically used in industrial air and water systems. The specific material for each fitting is indicated in the product specifications, such as the Type D forged brass coupling (MPN G200-D-BR) or the Type C stainless steel coupling (MPN G250-C-SS).
What is the maximum working pressure for Dixon stainless steel cam and groove couplings?
Dixon stainless steel cam and groove couplings have a maximum working pressure of 150 psi at 70°F for Type C couplings, as seen in the G250-C-SS model. Type AL stainless steel adapters, such as the 150-AL-SS, are rated to 250 psi at 70°F. Pressure ratings vary by fitting type, size, and material; always verify the specific product's pressure rating from the manufacturer's documentation before installation.
What gasket material is standard in Dixon cam and groove fittings?
The standard gasket material in Dixon cam and groove fittings is nitrile (Buna-N). Nitrile provides good resistance to petroleum-based oils, fuels, and water, with a typical temperature range of -20°F to 180°F. For applications requiring different chemical compatibility or temperature ranges, alternative gasket materials such as EPDM, Viton, or Teflon may be available; consult the product specifications or Dixon's catalog for options.
Are Dixon dust caps compatible with cam and groove couplings from other manufacturers?
Dixon dust caps, such as the Type DC 316 stainless steel dust cap (MPN RH600EZ), are designed to meet industry-standard cam and groove dimensions, making them interchangeable with couplings and adapters from other manufacturers that comply with the same dimensional standards (e.g., MIL-C-27487). However, always verify the coupling size and gasket compatibility to ensure a proper seal and locking arm function.
What is the thread specification for Dixon forged brass cam and groove couplings?
Dixon forged brass cam and groove couplings use NPT (National Pipe Taper) threads. For example, the 2 in coupling (MPN G200-D-BR) has a thread size of 2 in -11-1/2, and the 1 1/4 in coupling (MPN BD125EZ) has a thread size of 1-1/4 in -11-1/2. These threads are standard for pipe connections in North America and are compatible with NPT female fittings.
