| Worm-Drive (Screw-Band) | A screw turns through slots or perforations in a band, tightening it around the hose. | General-purpose plumbing, automotive, appliance, and low-pressure air or fluid connections. | Adjustable, removable, widely available, and suitable for a broad range of hose diameters. | Choose a band and housing that do not damage the hose. Not every design is suitable for high pressure, high vibration, or soft, thin-walled hose. |
| T-Bolt | A bolt and nut draw a wide band together to provide strong, relatively even circumferential clamping. | Larger-diameter or heavy-duty hose connections, such as some charge-air, cooling, and industrial hose assemblies. | Offers high clamping force and a robust construction when correctly sized and installed. | Requires the correct clamp range and tightening procedure. Suitability depends on the hose, fitting, operating conditions, and manufacturer specifications. |
| Spring-Band | A pre-formed spring-steel band applies continuing radial force as the hose diameter changes. | Selected vehicle cooling and heating systems, particularly connections exposed to temperature-related expansion and contraction. | Can maintain tension through normal thermal cycling without routine readjustment. | Usually requires suitable access or a clamp tool for installation and removal. Must match the hose diameter and intended application. |
| Wire | One or more formed wires tighten around the hose, concentrating pressure along narrow contact lines. | Some suction hoses, flexible ducts, and applications where a compact clamp profile is useful. | Can provide a secure hold with a relatively small external profile. | Narrow contact areas can mark or damage unsuitable hose materials. Confirm that the hose design is compatible with wire clamping. |
| Ear (Crimp) | A tool crimps one or more raised ears, reducing the clamp diameter to create a fixed connection. | Small-diameter fluid, fuel, and coolant hose assemblies where a compact, low-profile joint is needed. | Compact and tamper-resistant after installation; does not rely on a screw housing. | Generally requires a dedicated crimping tool and is not readily adjustable or reusable. Correct sizing and crimping are essential. |
| Constant-Tension (Spring-Loaded Screw) | A screw-tightened band incorporates a spring element that helps accommodate changes in hose diameter. | Selected connections subject to temperature changes or ongoing vibration, when the clamp is specified for that service. | Combines adjustable installation with some ability to compensate for dimensional changes. | Designs vary. Verify the clamp’s working range and application suitability rather than assuming it fits every dynamic or high-pressure connection. |
