Brand: Grafco (Graham-Field Health Products)
Product Type: C-Clamp Screw Compressor / Tubing Clamps
Quantity: Lot of 8 Matching Units
Country of Manufacture: Hong Kong
Material: Chrome-Plated Steel / Heavy Duty Metal
Item Description:
Up for sale is a vintage lot of 8 genuine Grafco metal C-clamp screw compressors. Originally designed for the precise manual occlusion, compression, and flow restriction of medical and laboratory tubing up to 1/2 inch in diameter, these heavy-duty clamps are highly sought after for both vintage medical collections and practical everyday workshop or laboratory applications.
Each clamp features an over-engineered hinged top plate equipped with a quick-release catch mechanism, allowing you to quickly loop the clamp over connected hoses or lines without having to unhook them. The knurled, serrated thumb screw dial turns smoothly to supply precise compression control down to the lower gate plate.
Condition Details:
- Overall Condition: Great vintage pre-owned condition with a beautiful polished chrome finish.
- Mechanical Function: All 8 units have been hand-tested. The top locking hinges latch tightly, and all 8 thumb screws turn smoothly and adjust perfectly down the threads.
- Cosmetics: The metal shows minor light surface scuffs, tiny handling scratches, and small spots of typical vintage tarnish from storage (as pictured), but they remain completely clean and structurally sound with no rust.
- Markings: Every individual clamp in this lot is cleanly stamped with the "GRAFCO HONGKONG" maker's mark on the swinging top bracket.
Features:
- Premium chrome-plated steel construction delivers excellent durability and rust resistance.
- Ergonomic serrated thumb screw design prevents hand slippage for reliable manual compression.
- Swing-open top latch bars allow for easy side-loading onto existing fluid lines or lab setups.
