Premium Heavy-Duty Hose Clamp 50 70mm – Secure Connection for Industrial Systems
Product Overview
Our hose clamp 50 70mm is a high-performance clamping solution engineered for demanding industrial, automotive, and hydraulic applications. Designed to accommodate hose outer diameters from 50mm to 70mm, this clamp provides a reliable, leak-proof seal under extreme pressure and temperature conditions. Manufactured from premium-grade stainless steel, it offers exceptional corrosion resistance and long service life. Whether you need to secure coolant hoses in heavy machinery or fuel lines in marine engines, this versatile clamp delivers consistent clamping force without deforming the hose.
Key Features
- Precision Diameter Range: Optimized for hose outer diameters between 50mm and 70mm, ensuring a snug fit without over-tightening.
- Heavy-Duty 304 Stainless Steel Construction: Resists rust, chemical corrosion, and UV degradation, suitable for outdoor and harsh environments.
- Wide Band Design: Distributes clamping pressure evenly across the hose surface, preventing damage to soft or thin-walled hoses.
- Quick-Release Worm Gear Mechanism: Allows fast installation and adjustment with a standard screwdriver or socket wrench, reducing downtime.
- Smooth Rolled Edges: Eliminates sharp burrs that could cut into hoses or injure operators.
- High Torque Capacity: Withstands vibration and thermal expansion cycles without loosening.

Application Scenarios
The hose clamp 50 70mm is a versatile component used across multiple industries:
- Automotive & Heavy Equipment: Securing radiator hoses, intercooler boots, turbocharger oil lines, and air intake systems in trucks, buses, and construction vehicles.
- Industrial Hydraulics & Pneumatics: Connecting high-pressure hoses in hydraulic presses, injection molding machines, and pneumatic conveyor systems.
- Marine & Offshore: Clamping bilge pump hoses, engine cooling lines, and fuel vent pipes in boats and offshore platforms.
- Agricultural Machinery: Fixing irrigation hoses, sprayer system lines, and hydraulic couplings on tractors and harvesters.
- HVAC & Refrigeration: Sealing refrigerant hoses, condensate drain lines, and ductwork connections in commercial HVAC systems.
- Food Processing & Beverage: Sanitary-grade option available for washdown environments (upon request).
Advantages
- Superior Clamping Force: The worm gear mechanism generates a consistent 360° radial force, eliminating leaks even under pulsating pressure.
- No Hose Damage: Unlike traditional ear clamps or spring clamps, our wide band prevents "hose necking" and material fatigue at the clamping point.
- Reusable & Adjustable: Can be removed and re-tightened multiple times without losing performance, ideal for maintenance and repair operations.
- Global Compliance: Meets DIN, SAE, and ISO standards, ensuring compatibility with international OEM specifications.
- Cost-Effective Solution: Reduces replacement frequency compared to low-cost zinc-plated clamps; stainless steel version offers lifetime value.

FAQ
Q1: What is the exact clamping range of this hose clamp 50 70mm?
A: The clamp is designed to fit hose outer diameters from 50 mm to 70 mm. For the best seal, we recommend selecting a clamp where the hose OD falls in the middle of the range (approx. 58-62 mm).
Q2: Can this clamp be used for high-temperature steam lines?
A: Yes, the standard 304 stainless steel version can handle continuous temperatures up to 150°C. For steam applications above 150°C, we recommend our 316L stainless steel variant with a higher temperature rating.
Q3: How do I determine the correct tightening torque?
A: For most rubber hoses, we recommend a torque of 4–6 N·m. Over-tightening may damage the hose or strip the worm gear. Use a torque wrench for critical applications.
Q4: Is this clamp suitable for silicone hoses?
A: Absolutely. The wide band design minimizes stress concentration, making it ideal for soft silicone hoses used in turbo and intercooler systems. Consider using our 14 mm wide band option for extra protection.
Q5: Do you offer bulk discounts for OEM orders?
A: Yes, we provide tiered pricing for quantities above 1,000 pieces. Contact our sales team for a customized quotation based on your annual volume and packaging requirements.
Q6: What is the typical lead time for custom orders?
A: Standard production takes 10–15 working days. Custom sizes or materials may require 20–25 working days. Express shipping options are available.
Q7: How do I install this clamp correctly?
A: Slide the clamp over the hose before connecting the fitting. Position the housing at least 3 mm from the end of the hose. Tighten evenly until the hose compresses slightly—do not overtighten. For detailed instructions, download our installation guide from the product page.
