Product Overview
The Swagelok SS-103-1 is the front ferrule for 1/16 inch Swagelok tube fittings, the small cone that seats against the fitting body and forms the seal in Swagelok's two-ferrule design. This pack is listed and sold as ten pieces. The material is 316 stainless steel per the bag label, which also carries batch R1NEH0337S, a US country of origin, and Qty 10; the label backs the material, the batch, the origin, and the count alike. Front ferrules are consumables in a working lab or process line: they go on the shelf with the nuts and back ferrules, which are separate part numbers, and they get pulled whenever a 1/16 inch connection is remade. At roughly 3 mm long each, these are easy to lose and easy to run short of, which is the usual reason someone goes looking for a small pack instead of a full box.

Frequently Asked Questions
Is this the front ferrule or the back ferrule?
Front ferrule only. SS-103-1 is the piece that seats against the fitting body. The back ferrule and the nut are separate Swagelok part numbers and are not included here.
How many ferrules ship?
Ten. The bag is Swagelok's original packaging and its printed label reads Qty 10, which is the count in this pack. The ferrules lie loose and overlapping inside the bag, so they are easier to count in the hand than on screen, but ten is what goes in the box.
What is actually confirmed about the material and origin?
The bag label reads 316 Stainless Steel Front Ferrule for 1/16 in. Swagelok, batch R1NEH0337S, CoO US. That is the confirmation we have. Anything beyond what the label prints is not confirmed - check the current Swagelok documentation for your fitting before use.
Will these work with the 1/16 inch fittings already on my bench?
They are the standard front ferrule for 1/16 inch Swagelok tube fittings, and in that system the nut, front ferrule, and back ferrule work as a matched set. Verify the fitting you are assembling against Swagelok's own installation guidance before making up the connection.
Why buy ten pieces here instead of a full box of ferrules?
Because ten is usually the number you actually need. A ferrule this small is a consumable, and most benches burn through two or three at a time when a line gets remade - not fifty. This pack is photographed, counted, and priced on its own, so you can restock the drawer without carrying a box you will still be opening in five years. Shipping is $8 flat rate and free once your order passes $28, and orders leave our Idaho warehouse the same or next business day.
Three millimeters of 316 stainless, and the whole leak-tight joint depends on it. The next 1/16 inch connection you make up is the one these were saved for.
