Pipe coupling types: how to choose the right connection

The Pipe Coupling Type range includes aluminum joints with iron caps, aluminum joints with iron outer screws, O-Ring connections, Flare connections, and Quick Joint configurations. Available geometries include straight, 45-degree, and 90-degree versions. The listed sizes include #5/16, #6, #8, #10, and #12, with UNF screw specifications shown for many configurations.

What pipe coupling types are available?

The range includes female O-Ring fittings, female Flare fittings, Quick Joint fittings, male O-Ring fittings, and male Flare fittings. The product list also separates configurations by connection angle: straight, 45 degrees, and 90 degrees. For example, FT2001 is a #5/16 straight female O-Ring fitting with a 9/16-18UNF screw specification, while FT2002 and FT2003 are the 45-degree and 90-degree versions for the same size and connection family.

How do I choose between an O-Ring, Flare, and Quick Joint connection?

Start with the connection style required by the mating hose or pipe assembly. O-Ring and Flare fittings are listed in female and male configurations, while Quick Joint fittings are listed as straight, 45-degree, and 90-degree options for #6, #8, #10, and #12 sizes. Match the fitting type, gender, size, angle, and screw specification to the existing assembly. If the line needs a change in routing, compare the straight, 45-degree, and 90-degree versions before ordering.

Which sizes and thread specifications are listed?

The range lists #5/16, #6, #8, #10, and #12 sizes. Examples include 9/16-18UNF for #5/16 female O-Ring fittings, 5/8-18UNF for #6 female O-Ring and Flare fittings, 3/4-16UNF for #8 female Flare fittings, 7/8-14UNF for #10 female O-Ring and Flare fittings, and 1.1/16-14UNF for #12 female O-Ring and Flare fittings. Male configurations are also listed with their own UNF specifications, so the mating thread should be checked against the selected part.

What information should I provide when ordering?

Provide the required size, connection family, angle, gender, and mating thread specification. State whether the assembly needs an O-Ring, Flare, or Quick Joint configuration, then identify a straight, 45-degree, or 90-degree layout. A part number such as FT2001, FT2002, or FT2003 can also identify the required configuration when it matches the intended assembly. Send a drawing or the existing fitting details when the thread, angle, or connection style needs confirmation.
