This 10N28 collet body kit is a small set of TIG torch consumables: five 10N25 collets and five 10N28 collet bodies, sized for 1/8 in (3.2 mm) tungsten. The 10N-series parts fit the common 17, 18 and 26 style TIG torches. Buy it if your torch uses these parts and 1/8 in tungsten; skip it if you run smaller tungsten or a gas lens setup.

What the 10N28 Collet Body and 10N25 Collet Do
The collet grips the tungsten electrode. The collet body threads into the torch head, holds the collet and routes shielding gas to the cup. Retailers list the 10N28 as the standard collet body with a 1/8 in bore for 17, 18 and 26 series torches, and the 10N25 as the matching 1/8 in collet.
Both are wear parts. A collet that no longer grips, or a body with damaged threads or a gas leak, makes the arc wander and the tungsten slip.
Check Fit Before You Order
- Confirm your torch is a 17, 18 or 26 style torch that uses 10N-series consumables.
- Confirm you run 1/8 in (3.2 mm) tungsten. Smaller electrodes need different collets and bodies.
- If you use a gas lens, you need gas lens collet bodies, not this kit.
- Match the part numbers (10N25 and 10N28) against your existing consumables.
The listing mentions a 150 A to 350 A range and other brands. Those claims are not supported by manufacturer data here, so check your torch rating in its manual and do not exceed it.
When to Replace Collets and Bodies
- The tungsten slips or will not stay centered when you tighten the back cap.
- Threads feel rough or the body will not seat firmly.
- You see discoloration, cracks or heat damage.
- You hear or suspect a gas leak around the head.
Tighten parts by hand or only snugly. Overtightening can strip threads and crush the collet.
