Tube fittings catalogue simplifies selection and use

Keywords Parker Hannifin, Catalogues

Parker Hannifin has published a free 80-page catalogue detailing twin-ferrule tube fittings and accessories for fluid instrumentation applications. The publication provides designers with an easy-to-use product guide combined with useful engineering information including a report detailing assembly and remake procedures, and a gauging procedure to verify correct assembly.

Tube fittings are available in both metric and imperial sizes, and in an extensive range of materials and configurations. Using a visual index grouped by component category, selecting the right part from the choice of around 2,000 individual components is made easy. Technical data pages contain engineering diagrams with full dimensional data. Additional information includes a useful visual sizing chart for US and ISO threads and tube ends.

The components in the catalogue make up Parker's A-LOK tube fitting range, and all material options are listed in a raw material specification table, which details chemical requirements.

Standard fittings are available in 316 stainless steel. Other options include steel, brass, aluminium, nickel-copper (alloy 400), Hastelloy C, alloy 600, titanium, 6Mo, and Incoloy 625 and 825. Straight fittings are machined from cold finished bar stock, and shaped bodies (elbows, tees etc.) are machined from close grain forgings. For nuclear and other critical applications, stainless steel fittings are available with documented heat code traceability.
