Clamps for Quick-Clamp High-Vacuum Fittings
- For Use With: Air
- Temperature Range: 0° to 300° F
- Tubing: Use with 304/304L stainless steel, 316/316L stainless steel, or aluminum
- Specifications Met: ISO 2861
Connect quick-clamp fittings in high-vacuum applications. Clamps tighten by hand. They are aluminum, which is lightweight with good corrosion resistance.
Lever clamps are also known as toggle clamps.
Clamps with lanyard let you secure clamp to equipment.
