British Type Hose Clamp
| British hose clamps are heavy-duty non-perforated fasteners with thicker bands and a more robust structure, suitable for hose connection applications that require high clamping strength under high vibration and heavy load conditions, such as trucks, construction machinery, and marine environments. We adopt a standardized production system, with common band widths of 9.7mm, 11.7mm, and 12.7mm, and band thicknesses up to 0.8–1.0mm. Material options include fully galvanized steel (W1) and full stainless steel (W4), meeting your need for a stable SKU structure to suit different application markets. Regular sizes from 1/2" to 4 1/3" (000–5) are kept in stock, supporting stable supply. We also provide customization options such as reinforced structures, heavy-duty housings, and special screw types based on your requirements, with fast sampling and support for bulk cooperation. Feel free to contact us. | |||||||||
