Also known as tri-clamp fittings.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth.

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings.

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Connect pipe to pipe in low- to high-pressure applications. Pipe and fittings are measured by pipe size, which is an industry designation, not an actual measured size like hose, tubing, and duct. Pipe is typically rigid.
