stop-it Metal Tubing Clamps

Constructed entirely from premium galvanized steel and high-strength aluminum, the stop-it Metal withstands severe operating temperatures ranging from -80°C to 200°C. Like its PVDF counterpart, it features a retrofitting open-hook frame that allows technicians to install it directly onto existing, active fluid lines without disconnecting fittings or stopping process flows. The knurled adjustment screw compresses flexible hoses evenly over a broad surface area, protecting internal tube walls from pinch damage while providing fine drop-by-drop control up to a complete shut-off.

Key Functional Benefits:

• Extreme Thermal Operating Envelope: All-metal aluminum and steel architecture performs flawlessly across extreme thermal windows from -80°C up to 200°C, making it ideal for autoclaving, high-heat reactions, and cryogenic cold-room storage.
• Non-Disruptive Line Installation: The open steel hook design allows quick retrofitting onto pre-assembled, fully pressurised fluid lines without breaking tube connections or risking contamination.
• Wide-Area Hose Protection: Compresses flexible tubing over a broad surface area against a smooth steel backing hook, preventing local mechanical stress, cracking, or wall indentation.
• Stepless Volumetric Flow Control: The ergonomic knurled adjustment screw enables fine, stepless flow throttling, from delicate micro-drips to a total pressure-resistant fluid barrier.

Tubing Compatibility & Limits: Designed specifically for flexible polymer, silicone, rubber, and vinyl tubing. Safe for extreme thermal workflows (-80°C to 200°C). Do not attempt to use on rigid, non-compressible piping like glass, stainless steel, or unyielding PEEK.
