Construction and Materials
D-lok tube fittings are sequential phase-controlled action, sealing and gripping devices. Superior design, rigid manufacturing tolerances, and strict
quality assurance programs produce an all-metal sealing and holding device which performs leak-free when properly installed. D-lok tube fittings
consist of a body, a nut, and ferrules and are constructed of one of the following materials: brass. 316/304 stainless steel, steel, nickel alloy, monel,
or inconel. Straight fittings are machined from cold finished bar stock and shaped bodies are machined from close grain forgings. The materials used,
fully conform to the chemical requirements of one or more of the specifications listed in Table 5 on this page. Nut internals are supplied standard with
silver plating. For nuclear and other critical applications, stainless steel D-lok tube fittings are readily available with documented heat code traceability.
