Clamps for Claw-Clamp High-Vacuum Fittings for Stainless Steel Tubing
Connect claw-clamp high-vacuum fittings for an airtight seal. For a complete connection, you'll need four clamps and a ring (sold separately).
Double-claw clamps attach to the grooves on the fittings.
Single-claw clamps have a clamp on one end and an exposed bolt on the other. Thread the bolt-end directly into the body of pumps, valves, or other high-vacuum components.

Crimp-On Ferrules for Air and Water Hose
Use ferrules to create a permanent connection between your air- and water-hose and barbed hose fittings. You will need a hose crimper (sold separately) for installation.
Brass and aluminum ferrules have good corrosion resistance. Choose a ferrule with an ID no more than 0.025" larger than your hose OD (measured with the fitting installed); also make sure the ferrule is at least as long as the barbed end of your fitting.

Wire Rope Compression Sleeves—Not for Lifting
An economical option for light-duty tethering, securing, and suspending. Compression sleeves are also known as ferrules, crimps, swaging, and splicing sleeves. They're compatible with Nicopress compression tools.
Warning: Fittings must match rope diameter and be installed correctly to obtain maximum holding power. Test all assemblies for required strength before use. Do not use with coated rope unless the coating is removed.
