Ultra-High-Polish Gasket Fittings for Stainless Steel Tubing
![](/prerenderstable/mvPRE/contents/gfx/imagecache/906/9066nc1-c01f-digital-master1573770670-p9@halfx_637093595313800680.png?ver=imagenotfound)
- 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.

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.
