Clamps for Vacuum Fittings for Steel Tubing
Use these clamps to connect vacuum tube fittings. Insert two fittings into a clamp and tighten to form a secure seal.
For technical drawings and 3-D models, click on a part number.
- For Use With: Air, Glass, Plastic Pellets, Resins, Wood Chips
- Temperature Range: Neoprene Rubber Gaskets: -50° to 180° F
Silicone Rubber Gaskets: -100° to 500° F - Tubing: Use with steel
Bolt clamps have a stainless steel strip that provides an escape route for electrostatic buildup when used in a fully-grounded system. They have fair corrosion resistance.
Tube-End Weld Nuts
Weld these nuts to round uncoated metal tubes to attach threaded parts, such as rod ends. Also known as tube adapters and weldable threaded tube ends.
