Advanced Couplings manufactures ferrules in accordance with the relevant British and European standards, as itemised in the detailed ferrule section. Pharmaceutical grade Ferrules are produced by machining from 316L stainless steel bar stock. To comply with customer specifications, we can produce from certified bar to, (but not limited to);
ASTM A 182/SA 479/SB 574 etc
The surface finish is equal to or more often better than those quoted in the relevant standards. Ferrules are also available with enhanced surface finish to 0.38 um Ra, this being achieved by electro polishing, (also providing a passivated layer to the ferrule).
3.1 Material certification is available online and all ferrules are laser marked with the material grade, mill heat number and the fitting size and type. A Declaration of conformity is issued as standard.
Ferrules can also be supplied as specials in a variety of non-standard materials such as special stainless steels, titanium, hastelloy, AL6XN etc.
As well as the extensive range of standard stock ferrules, we can supply customised ferrules to a wide range of requirements. We have many years’ experience of producing special ferrules and can offer a quick turn-around on such items, all produced to the same high quality as our standard range.
