DIXON VALVE & COUPLING

Dixon Valve & Coupling is a manufacturer of industrial fluid and gas transfer components, with a product history dating to the early 20th century. The company's catalog centers on hose couplings, cam and groove fittings, quick-connect pneumatic couplings, and related accessories used to join, terminate, and protect hose and pipe lines. Dixon products are commonly specified in compressed air systems, fluid transfer, chemical handling, and general industrial plumbing where repeated connect and disconnect cycles are required. 3G Electric supplies 447 Dixon SKUs, spanning cam and groove fittings in Type E, Type DP, and other configurations, as well as industrial interchange quick-connect air coupling plugs and bodies. The line includes forged brass cam and groove adapters and dust plugs, zinc-plated steel Bowes-style quick-connect air coupling bodies, and brass quick-connect plugs with sleeve locking. These components are available in coupling sizes from 1/4 in through 4 in, with thread types including FNPT and MNPT, and pressure ratings that vary by size and material. For technical buyers, Dixon fittings are selected based on coupling size, thread standard, body material, and locking mechanism. Cam and groove fittings rely on a gasket and cam arm closure for a seal, while quick-connect couplings use a push-to-connect or sleeve-lock interface for pneumatic tools and air lines. Dust plugs are used to seal open coupling ends during storage or idle periods, preventing ingress of dirt, debris, and moisture. 3G Electric supports the Dixon line by stocking a broad range of these SKUs and providing specification-level data for each part, including body size, hose fitting size, thread dimensions, overall length, and maximum working pressure at 70°F. This allows maintenance and procurement teams to match replacement fittings to existing installations without guesswork. The catalog includes both common and less-common sizes, such as 2 1/2 in and 3 in cam and groove components, as well as 1/4 in pneumatic quick-connects. Because Dixon fittings are used across plant air systems, fluid transfer lines, and washdown or chemical applications, material selection matters: forged brass offers corrosion resistance for many fluid and pneumatic duties, while zinc-plated steel is often used in air coupling bodies where a harder wearing surface is beneficial. 3G Electric's listing covers these material options and provides the dimensional and pressure data needed for cross-referencing. For buyers working with existing Dixon installations, the MPN and SKU structure allows direct lookup of parts such as G300-E-BR, D2M2-B, or G400-DP-BR. The product data includes UNSPSC classification for procurement systems and manufacturer part numbers for verification. 3G Electric ships these Dixon components globally, serving plant engineers, maintenance managers, and procurement specialists who need to specify or replace fittings in industrial air, fluid, and gas systems. The catalog is structured to support both one-off replacement orders and larger project requirements, with each SKU carrying the technical attributes necessary for engineering review.

Frequently asked questions

Common questions about DIXON VALVE & COUPLING from 3G Electric.

What sizes and thread types are available in Dixon cam and groove fittings from 3G Electric?

Dixon cam and groove fittings in the 3G Electric catalog include coupling sizes from 1 in to 4 in, with examples such as the Type E forged brass adapter in 3 in (MPN G300-E-BR) and Type DP forged brass dust plugs in 1 in, 2 in, 2 1/2 in, and 4 in. Thread types vary by part; the Type E adapter uses a hose fitting size of 3 in, while other cam and groove components may have FNPT or MNPT threads. Pressure ratings range from 100 psi to 250 psi maximum working pressure at 70°F, depending on size and configuration. Buyers should verify the specific coupling size, thread standard, and pressure rating required for their application against the individual product data.

What is the difference between Dixon Type E and Type DP cam and groove fittings?

Dixon Type E cam and groove fittings are adapters, typically used to connect a hose to a pipe or equipment. They have a male adapter end and a hose fitting end. Type DP fittings are dust plugs, which are used to seal open cam and groove coupler ends when the line is disconnected or idle. Dust plugs prevent dirt, debris, and moisture from entering the coupling. In the 3G Electric catalog, Type E is represented by forged brass adapters such as G300-E-BR, while Type DP is represented by forged brass dust plugs such as G100-DP-BR, G200-DP-BR, G250-DP-BR, and G400-DP-BR. Both types are available in forged brass.

What are the pressure ratings for Dixon Type DP forged brass dust plugs?

Dixon Type DP forged brass dust plugs in the 3G Electric catalog carry maximum working pressure ratings at 70°F that vary by coupling size. The 1 in, 2 in, and 2 1/2 in sizes are rated to 250 psi, while the 4 in size is rated to 100 psi. These ratings reflect the pressure-holding capability of the plug when properly installed on a compatible cam and groove coupler. Actual working pressure in a system may be limited by the hose, coupling, or other components. Always confirm the rating of the complete assembly and consider temperature derating for applications above 70°F.

What locking types are available on Dixon quick-connect air coupling plugs?

Dixon industrial interchange quick-connect air coupling plugs in the 3G Electric catalog feature a sleeve locking type. This means the plug is secured by a sleeve mechanism on the mating coupler. Examples include the D2M2-B plug with 1/4 in body size and 1/4"-18 MNPT male thread, and the D2F2-B plug with 1/4 in body size and 1/4" FNPT female thread. These plugs are designed for compressed air systems and pneumatic tools. The sleeve locking design allows for quick connection and disconnection. Buyers should match the plug body size and thread type to their existing coupler and hose or pipe connection.

What materials are used in Dixon cam and groove fittings and quick-connect couplings?

Dixon cam and groove fittings in the 3G Electric catalog are available in forged brass, which offers corrosion resistance for fluid and pneumatic applications. Quick-connect air coupling bodies, such as the Bowes steel body (MPN 4NF6), are made from zinc-plated steel for durability in compressed air systems. Quick-connect air coupling plugs are available in brass. Material selection should consider the media being transferred, operating temperature, and compatibility with other system components. Forged brass is common in general fluid transfer, while zinc-plated steel is often used in air line couplings where a harder surface is beneficial.

How do I identify the correct replacement Dixon fitting for my existing installation?

To identify the correct replacement Dixon fitting, start with the manufacturer part number (MPN) if it is visible on the existing component. The 3G Electric catalog lists MPNs such as G300-E-BR, D2M2-B, and G400-DP-BR, which can be cross-referenced directly. If the MPN is not available, measure the coupling size, thread size and type (FNPT or MNPT), and hose fitting size. Also note the body material and locking mechanism. For cam and groove fittings, the coupling size is the primary dimension. For quick-connect couplings, the body size and thread type are critical. The product data in the 3G Electric listing provides these specifications to help match the replacement part.
