stop-it Easy-Click Closure Tubing Clamps

Constructed from chemically inert, high-temperature Polyvinylidene Fluoride (PVDF) paired with a heavy-duty zinc-coated steel hook, the stop-it clamp delivers exceptional mechanical rigidity and thermal endurance up to 140°C. The patented Easy-Click latch mechanism lets operators open and snap the clamp shut at any point along a hose. Fluid compression occurs over a wide surface area against the steel frame, protecting delicate flexible tubing walls from pinch damage while enabling precise adjustment from micro-flow metering to total pressure-resistant shut-off.

Key Functional Benefits:

• Patented Easy-Click Retrofitting: Snaps open and shut anywhere along an active line, eliminating the frustration of threading tubing ends through closed clamp apertures.
• Broad Surface Pressure Distribution: Compresses flexible hoses over an extended surface area against a smooth, zinc-coated steel hook to prevent wall pinching, creasing, or material degradation.
• High-Temperature PVDF Matrix: Molded from premium PVDF resin, offering superior chemical resistance to acids, alkalis, and solvents, alongside an extended thermal rating up to 140°C.
• Stepless Volumetric Control: Ergonomic knurled screw allows technicians to dial in ultra-precise drop-by-drop flow rates or completely seal off gas and liquid transfers.

Thermal & Mechanical Operating Envelope: Designed for flexible polymer, rubber, silicone, and vinyl tubing. Safe for ambient to high-temperature workflows up to 140°C (minimum rating: -40°C). Do not apply to rigid, non-compressible piping like glass, acrylic, or unyielding PEEK.
