39-47mm Heavy‑Duty W4 Reinforced Hose Clamp
Techi industrial W4 reinforced heavy‑duty hose clamp (also known as double‑band bolt hose clamp, abracadeira mangote reforçada) is engineered for high‑pressure, heavy‑duty hose fastening applications. The 86‑94 mm clamping diameter provides a secure, uniform, high‑torque grip on rubber hoses, silicone hoses, hydraulic pipes, exhaust hoses and industrial tubing.
Made from premium W4 304 stainless‑steel, this robust hose clip delivers outstanding rust resistance, anti‑corrosion performance and long‑term service life even in harsh outdoor, marine, chemical and wet‑environment working conditions. Unlike standard worm‑drive hose clamps, this reinforced double‑band design distributes tightening force evenly around the hose surface, preventing hose damage, slippage and fluid leakage under vibration or high‑pressure loads.

39-47mm Heavy‑Duty W4 Reinforced Hose Clamp Product Features:
1. Heavy-Duty Reinforced Construction
The reinforced clamp structure provides high mechanical strength and stable clamping performance, making it suitable for heavy-duty hose connection applications.
2. W4 Stainless Steel Material
The W4 specification offers excellent corrosion resistance and durability. It is suitable for demanding environments where reliable stainless steel hose clamps are required.
3. Strong Worm Gear Drive
The precision worm gear mechanism allows easy tightening and adjustment while providing consistent clamping force around the hose.
4. 39-47mm Adjustable Clamping Range
Designed for hose outside diameters from 39mm to 47mm, this adjustable hose clamp accommodates different hose sizes within the specified range.
5. Secure 360° Clamping
The perforated stainless steel band distributes clamping pressure evenly around the hose, helping reduce leakage and prevent hose movement.
6. Wide Application Range
Suitable for industrial machinery, automotive systems, agricultural equipment, water pipes, air hoses, hydraulic systems, pneumatic equipment, and fluid transfer applications.
39-47mm Heavy‑Duty W4 Reinforced Hose Clamp Installation & Usage Tips:
- Place the open clamp around the outer diameter of your hose / pipe.
- Tighten the hex bolt gradually with standard spanner or socket wrench.
- Do not over‑torque, to avoid crushing the hose wall.
- The flexible band will automatically maintain stable tension after installation, even with temperature cycling.
