Ultra-High-Polish Gasket Fittings for Stainless Steel Tubing
- For Use With: Argon, Helium, Nitrogen
- Temperature Range: -420° to 1000° F
- Tubing: Use with 316/316L stainless steel
- Compatible With: Swagelok® VCR
The 15 Ra finish on the interior of these fittings creates an ultra-smooth surface. Also known as ultra-high-purity fittings, they are packed in a Class 100 clean room to prevent contamination. They are commonly used in semiconductor applications. Fittings use a metal gasket (sold separately), which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Fittings are 316 stainless steel for excellent corrosion resistance.

| 1/2" | 0.049" | 1 1/8" | 316L Stainless Steel | 3,500 psi @ 72° F | 10 -11 torr @ 72° F | 0000000 | 000000 |
Use a female nut to connect a threaded adapter or a Yor-Lok adapter with a butt-weld adapter.
Nuts for Ultra-High-Polish Gasket Fittings for Stainless Steel Tubing
- For Use With: Argon, Helium, Nitrogen
- Temperature Range: -420° to 1000° F
- Tubing: Use with 316/316L stainless steel
- Compatible With: Swagelok® VCR
Nuts are 316 stainless steel for excellent corrosion resistance.
To connect two butt-weld adapters, use a male nut and a female nut. To connect a threaded adapter or a Yor-Lok adapter with a butt-weld adapter, use a female nut. Nuts and adapters are sold separately.

Vibration-Resistant Ultra-High-Polish Gasket Fittings for Stainless Steel Tubing
- For Use With: Argon, Helium, Nitrogen
- Temperature Range: -420° to 1000° F
- Tubing: Use with 316/316L stainless steel
Polished to a 7 Ra finish on the inside, these fittings have an ultra-smooth interior surface. Also known as ultra-high-purity fittings, they are packed in a Class 100 clean room to prevent contamination. They are commonly used in semiconductor applications. Fittings use a metal gasket, which generates fewer particles than a rubber gasket and creates a strong seal in high-pressure and high-vacuum applications. Two anti-torque rings further reduce particle generation by preventing the metal gasket from twisting and loosening. Fittings are 316 stainless steel for excellent corrosion resistance.
