With no metal parts, these valves are often used for noncontact flow adjustment in wet conditions and harsh environments. All press down on the outside of tubing to adjust flow without contacting the process media.

For installation in instrument panels, these valves have a hex nut and threads below the handle. They press down on the outside of tubing to adjust flow without contacting the process media.

These clamps are easier to install than worm-drive clamps—crimp the pinch points with pinch-clamp pincers for a secure hold. They are also known as ear clamps.
