CAMPBELL FITTINGS

Campbell Fittings is a manufacturer of cam and groove couplings, with a product line centered on the Insta-Lock series. The company produces fittings in a range of configurations, including Type C (male hose shank) and Type DC (dust cap) variants, constructed from stainless steel. These components are designed for quick-connect/disconnect applications in fluid transfer systems, commonly used in industrial, agricultural, and chemical processing environments. The Insta-Lock design incorporates a locking arm mechanism that secures the coupling halves, with nitrile gaskets providing a seal suitable for a variety of fluids. Campbell Fittings products are rated to a maximum working pressure of 250 psi at 70°F, as indicated on the dust cap models. The Type C fittings are available in sizes from 1 inch to 4 inches, with corresponding thread sizes and overall lengths that vary by model. The stainless steel body material offers corrosion resistance, making these fittings appropriate for use in harsh or washdown environments. 3G Electric stocks a selection of Campbell Fittings cam and groove components, including both Type C and Type DC configurations, in multiple sizes. These products are supplied with nitrile gaskets and include locking arms as standard. 3G Electric supports global logistics for procurement and delivery of these fittings, enabling plant engineers and maintenance managers to source replacement or new-installation components for fluid handling systems. The product range covers common coupling sizes, allowing for integration with existing hose assemblies and equipment. Technical specifications such as coupling size, thread size, overall length, and material composition are provided for each SKU to facilitate selection. Campbell Fittings products are intended for use in applications requiring reliable, repeatable connections for liquid or dry bulk transfer, where quick coupling and uncoupling is needed without tools. The stainless steel construction and nitrile gasket material are selected for durability and compatibility with a range of media. 3G Electric offers these components as part of its industrial equipment catalog, with availability for international shipment.

Frequently asked questions

Common questions about CAMPBELL FITTINGS from 3G Electric.

What is the maximum working pressure for Campbell Fittings Type DC dust caps?

The Campbell Fittings Type DC stainless steel cam and groove dust caps, such as the QCG-DC150-SS, are rated to a maximum working pressure of 250 psi at 70°F. This rating applies to the coupling assembly when properly connected and locked. The pressure rating is based on the body material and gasket performance; for applications at higher temperatures or with aggressive media, consult the manufacturer's guidelines for derating factors.

What gasket material is used in Campbell Fittings cam and groove couplings?

Campbell Fittings cam and groove couplings, including both Type C and Type DC configurations, are supplied with nitrile gaskets. Nitrile (Buna-N) is a synthetic rubber with good resistance to petroleum-based oils, fuels, and hydraulic fluids, as well as water and some chemicals. It operates effectively within a temperature range typically from -20°F to 250°F, making it suitable for many industrial fluid transfer applications.

Are Campbell Fittings Type C couplings available in sizes other than 1 to 4 inches?

Based on the product range stocked by 3G Electric, Campbell Fittings Type C stainless steel cam and groove fittings are available in coupling sizes of 1 inch, 1-1/2 inches, 3 inches, and 4 inches. These correspond to thread sizes of 1 inch, 1-1/2 inches, 3 inches, and 4 inches respectively. The overall length varies by size, from 4-1/4 inches for the 1-inch model to 7-7/32 inches for the 4-inch model. For other sizes, check with 3G Electric for availability.

What is the difference between Type C and Type DC Campbell Fittings?

Type C Campbell Fittings are male hose shank couplings designed to connect to a hose end, providing a male thread or shank for attachment. Type DC are dust caps, which are used to cover and protect the coupling end when not in use, preventing contamination and damage. Both types are part of the Insta-Lock cam and groove system and share the same body material (stainless steel) and gasket material (nitrile). The dust caps include a locking arm to secure them in place.

Can Campbell Fittings stainless steel couplings be used with other cam and groove brands?

Campbell Fittings cam and groove couplings are designed to the standard cam and groove profile, which is an industry-standard configuration. This means they are generally interchangeable with couplings from other manufacturers that conform to the same dimensional standards, such as those specified in MIL-C-27487 or A-A-59326. However, for critical applications, it is recommended to verify compatibility by checking dimensions and gasket seating to ensure a proper seal.
