Advanced Couplings manufactures ferrules in accordance with the relevant British and European standards, as itemised in the detailed ferrule section. Ferrules are produced by turning from 316L (ASTM A240-78) or 316S11 (BS970 PART 1: 1983) {both low sulphur grades offering good weld ability} stainless steel bar stock.

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).

Material certification is supplied as standard and all ferrules are part marked with the material grade, mill heat number and the fittings size and name. Certificates of conformity are also issued on request.

Ferrules can also be supplied as specials in a variety of non-standard materials such as special stainless steels, titanium, hastalloy, AL6XN etc.

As well as the extensive range of standard stock ferrules we can supply customised ferrules to virtually any 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.
