Constant Pressure T-Bolt Hose Clamp – 48–51mm (316 Stainless Steel)

• Automatically self-adjusts tension using a 12-spring washer stack for constant pressure.
• Extra-wide 30mm stainless band ensures reliable sealing on heavy-duty hoses.
• M10 bolt and integrated anti-extrusion bridge prevent hose bulging or deformation.
• Built from corrosion-proof 316 stainless steel for use in marine, automotive or industrial settings.
• Fits hoses with 48–51mm OD – ideal for high-pressure systems and boost pipe installations.

The 48–51mm constant pressure clamp provides a high-performance sealing solution for demanding applications. Its spring-loaded mechanism maintains consistent tension as hoses expand and contract, ensuring a leak-free seal without manual re-tightening. The 30mm wide band offers uniform compression, and the reinforced bridge shields against extrusion. Made entirely from 316 stainless steel, this clamp resists saltwater, pressure, and vibration with ease.
