Heavy-Duty Stainless Steel Worm Gear Hose Clamps – Adjustable Pipe & Hose Jubilee Clip Fasteners (Multi-Size Selection)
Heavy-Duty Stainless Steel Worm Gear Hose Clamps – Adjustable Pipe & Hose Jubilee Clip Fasteners (Multi-Size Selection)
Secure flexible hoses, rubber pipes, plastic tubing, and ventilation ducts onto barbed fittings and nipples with our Premium Stainless Steel Worm Gear Hose Clamps. Engineered with a precision-threaded perforated band and a heavy-duty worm drive mechanism, these adjustable hose clamps deliver 360-degree uniform radial clamping pressure to prevent fluid, gas, and air leaks under pressure and vibration.
Featuring a slotted hex head screw, these clamps can be tightened or loosened easily using a flathead screwdriver, socket wrench, or hex nut driver. Built from corrosion-resistant stainless steel, they are essential fastening components for automotive plumbing, garden hose connections, agricultural irrigation, marine bilge pumps, home appliance connections, and industrial HVAC ductwork.
Key Features
-
Uniform 360° Radial Sealing: Perforated band threads engage smoothly with the worm drive screw, creating a tight, leak-proof seal around flexible hoses.
-
Corrosion-Resistant Stainless Steel: Resists rust, moisture, fuels, oils, and mild acids in automotive, marine, and outdoor environments.
-
Slotted Hex Drive Screw: Tightens easily using a standard 7mm/8mm socket, nut driver, or flathead screwdriver for flexible field installation.
-
Smooth Inner Band Edges: Smooth, burr-free band underside prevents slicing, gouging, or damaging soft rubber and silicone hoses during high-torque tightening.
-
Wide Adjustable Size Range: Continuous thread track allows wide clamping diameter adjustment to fit various hose outer diameters (OD).
