This 10-pack of TIG gas lens cups (ceramic) is meant for WP-9/20 and WP-17/18/26 style torches when paired with the matching gas lens collet bodies. A gas lens smooths the shielding gas flow so you can stick the tungsten out farther and still get clean coverage. The cups only help if the rest of your gas lens parts match.
Quick Facts

| Torch series | WP-9/20 and WP-17/18/26 |
| Matching parts named | 45V gas lens collet body and 13N collet for WP-9/20; 17GL stubby gas lens and 10N stubby collets for WP-17/18/26 |
| Not included | Collets, gas lens bodies, tungsten, back caps |
What TIG Gas Lens Cups Do
The cup directs shielding gas around the tungsten and puddle. A gas lens sits behind the cup and uses a fine screen to turn rough gas flow into a smooth column. That gives better coverage when you need longer stickout, like on pipe, inside corners or joints with poor access.
The ceramic cup is the consumable. It cracks, chips or collects spatter and eventually needs replacing.
Make Sure the Cups Fit Your Setup
- Identify your torch series. The listing names WP-9/20 and WP-17/18/26.
- Check that you have gas lens collet bodies. A standard collet body will not work with these cups as intended.
- Compare the cup diameter and length (listing: 12.5 x 25.5 mm) with the cup you use now.
- Confirm the cup seats and seals on the gas lens O-ring with no wobble.
The listing also mentions Lincoln, Miller and ESAB torches. Treat that as a loose hint, and confirm with your own torch parts.
Tips for Using Ceramic Cups
- Hand-tighten only. Ceramic cracks if overtightened or dropped.
- Inspect for chips before each session. A cracked cup can leak gas or fail.
- Set gas flow for your cup size and job; larger gas lens setups can use more flow.
- Keep the lens screen clean. A clogged lens defeats the purpose of the upgrade.
Pros and Limitations
Pros
- Ten cups cover heavy use or training use.
- Ceramic handles arc heat for normal TIG work.
- Pairs with a gas lens kit for better control over coverage.
Limitations
- Fit depends on matching gas lens parts, which are not included.
- Brand, warranty and exact ceramic grade are not clear on the listing.
- Ceramic is fragile and not suited for high-impact shop use.

Frequently Asked Questions
What does a gas lens do for TIG welding?
It smooths the shielding gas into a steady column. That protects the weld better, especially with longer tungsten stickout.
Are gas lens cups interchangeable with standard cups?
Not always. Gas lens cups are used with gas lens collet bodies, so match them to your torch parts.
How much gas flow should I use with a gas lens?
Start with your torch maker’s guidance. Gas lenses often work well with a lower flow than standard cups, but conditions vary.
Why do ceramic cups crack?
Overtightening, drops, heat shock or contact with the weld can crack them. Hand-tighten and replace chipped cups.
Bottom Line
A sensible spare-parts pack if you already run a compatible gas lens torch. Do not buy it as a first gas lens upgrade because it does not include the lens bodies.
