DK-LOK Compression Fitting Twin Ferrule Set, 1/2" Tube OD, SS316, DFS-8-S

Swagelok SS-810-SET

Swagelok Tube Fitting Ferrule Set ("-SET"), Gaugeable Tube Fittings, catalogue MS-01-140

Swagelok SS-810-SET is Swagelok's 1/2 in. 316 stainless steel ferrule set — one front ferrule and one back ferrule — for Swagelok tube fittings, and Swagelok supplies it in multiples of ten. The part listed on this page is DK-LOK DFS-8-S, the equivalent 1/2 in. 316 stainless steel twin-ferrule set for DK-LOK tube fittings, offered as a single set. Ferrules are body-specific: each manufacturer specifies its ferrules for use only in its own fitting bodies, and Swagelok's catalogue advises against mixing ferrules, nuts and bodies from different manufacturers. DFS-8-S is therefore a like-for-like alternative set for DK-LOK fittings, not a service part for a Swagelok body.

Hy-Lok CFS-8-S316

Hy-Lok CFS Ferrule Set — spare parts for Hy-Lok two-ferrule tube fittings

Hy-Lok CFS-8-S316 is a ferrule set for 1/2 in. (12.70 mm) tube OD in 316 stainless steel, comprising one front ferrule and one back ferrule (Hy-Lok catalogue H-200TF, p. 69). indSpare stocks the DK-LOK DFS-8-S twin ferrule set, which matches it on tube OD, material and set composition. The two are listed as equivalents, not as interchangeable components: Hy-Lok's catalogue cautions against intermixing components of other manufacturers, so each brand's ferrules should be used with that brand's fitting body and nut.
