Polished to a 10 Ra finish on the inside, this tubing has the smoothest interior of any tubing we offer. It is commonly used in semiconductor applications.

Take samples in sanitary environments—these tube fittings won’t contaminate your lines or force you to pause them.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

Use these nuts with compression sleeves and fittings to create a strong seal on stainless steel tubing.

When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal.

The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.
