The CK 2P18GSLD replacement Pyrex cup is the clear glass cup used with CK’s 2 Series large-diameter Gas Saver assemblies. It replaces the cup on an existing compatible setup rather than supplying a complete gas-distribution kit.
Replacement cup details
- Part: 2P18GSLD
- System: 2 Series large-diameter Gas Saver
- Material: clear glass
- Nominal opening: 1-1/8 inch
- Manufacturer-listed length: 1-9/32 inch

Match the complete Gas Saver assembly
This push-on cup is intended for the matching large-diameter components used on compatible CK9/CK20-style setups. It is not a direct substitute for a threaded standard ceramic cup, and it does not include the heatshield, collet body or tungsten adapter screen.
Order by the complete part number. The cup opening does not identify the tungsten diameter; the installed collet and adapter must match the electrode. Follow CK’s fitting instructions and check the existing components before replacing a damaged cup.
Complete kits and other cups
Matching complete kits are available for 1/16 inch, 3/32 inch and 1/8 inch tungsten. For the separate 4 Series large-diameter system, see 4P18GSLD. Contact Justram with your kit reference if you need a fit check.
