This TIG ceramic cup kit set bundles alumina-style nozzle cups in sizes 12#, 14#, 16# and 24# for compatible TIG torches, with a stainless steel filter screen for gas flow. Per the listing it fits WP9, WP20, WP25, WP17, WP18 and WP26 style torches. It is a consumables kit, not a torch, and this page is based on the listing rather than hands-on testing, so match your torch model and cup size before buying.

The quoted 2.4 mm inner diameter cannot be the cup opening, because cup numbers refer to the opening size. Treat it as a bore dimension and confirm what it applies to on the listing.
Which TIG Ceramic Cup Size Should You Use?
A common convention is that the cup number is the opening diameter in sixteenths of an inch, so a 12# cup is about 3/4 inch and a 16# cup is about 1 inch. Check the listing for the actual dimensions of each cup.
- Smaller cups (12#, 14#): better access in tight corners and joints, with a narrower gas shield.
- Larger cups (16#, 24#): a wider shielding gas envelope for open joints, aluminum or longer stick-out. They need more gas flow and are bulkier.
Fit Checklist Before You Buy
- Identify your torch model (WP9, WP17, WP20, WP25, WP26 and so on) from the body or manual.
- Confirm the cups thread or seat onto your collet body or gas lens. A gas lens and a standard collet body use different cups.
- Check the tungsten diameter and collet size you use match the rest of your consumables.
- Make sure the kit includes the parts you need; the listing is the source for contents.
Use and Care
- Hand-tighten cups gently. Ceramic cracks if overtightened or knocked against the workpiece.
- Inspect for cracks and chips before each session, and replace any damaged cup.
- Let cups cool before swapping them, and wipe off spatter or contamination.
- Clean with a dry cloth or soft brush. Avoid abrasives that can scratch the inside.
- Wear a proper helmet, gloves and clothing, and ventilate your work area.
Pros and Limitations
Pros: multiple cup sizes in one kit, a filter screen included per the listing, and several torch styles named.
Limitations: ceramic is brittle, cup dimensions and kit contents are not independently verified here, and the kit is for TIG only.
