Secure and reliable connections are critical for industrial air hose systems, especially in construction, manufacturing, and agricultural operations. Air Hose Boss Clamp BU14 and Air Hose Boss Clamp BU24 are engineered to provide maximum sealing strength and operational reliability in these applications.
Manufactured from ductile iron, these clamps combine exceptional durability with vibration resistance and corrosion protection, making them ideal for high-pressure air hoses and demanding industrial environments.
An Air Hose Boss Clamp is a mechanical device designed to fasten hoses to boss fittings or pipe couplings. These clamps ensure airtight connections and prevent leakage in pressurized air systems.
The BU series, including BU14 and BU24, uses a double-bolt design, providing even clamping pressure and minimizing the risk of hose slippage. This makes them suitable for both fixed installations and portable air hose systems.
Key Features:
Double-bolt tightening for uniform clamping
Inner surface precision-machined to protect hoses
High-strength ductile iron construction
Anti-corrosion surface coating for long-term performance
Ductile iron (also known as nodular cast iron) is widely used for industrial clamps because it balances strength, toughness, and flexibility. Compared with standard cast iron or mild steel, ductile iron absorbs stress better and resists cracking under torque, which is essential for high-pressure air hoses.
| Property | Ductile Iron | Gray Cast Iron |
|---|---|---|
| Tensile Strength | 400–500 MPa | 200–250 MPa |
| Elongation | 10–15% | <1% |
| Fatigue Resistance | Excellent | Poor |
| Vibration Absorption | High | Low |
| Corrosion Resistance | Good | Moderate |
This makes Air Hose Boss Clamp BU14 and BU24 reliable even in demanding industrial applications.
| Model | Hose Outer Diameter (mm) | Bolt Size | Material | Pressure Range (bar) | Primary Application |
|---|---|---|---|---|---|
| Air Hose Boss Clamp BU14 | 50–65 | M10 | Ductile Iron | 8–10 | Light to medium air hose systems |
| Air Hose Boss Clamp BU24 | 65–90 | M12 | Ductile Iron | 10–12 | Medium to heavy-duty air hose systems |
The double-bolt design ensures the hose is evenly compressed along its circumference, preventing leaks and hose deformation.
Made from ductile iron, the clamps withstand mechanical stress, impact, and high air pressure, providing long-term durability.
Anti-corrosion coating protects against rust and chemical exposure, extending the life of the clamp in indoor and outdoor applications.
Bolts can be tightened using standard tools, and clamps can be removed or reused after inspection.
| Industry | Model | Use Case | Medium |
|---|---|---|---|
| Manufacturing | BU14 | Compressed air lines for machinery | Air |
| Agriculture | BU24 | Irrigation air-driven systems | Air and mist |
| Construction | BU24 | Portable pneumatic hose systems | Air |
| Automotive | BU14 | Air hoses in painting and tire systems | Air |
| Mining | BU24 | Pressurized air distribution | Air and dust-laden air |
Both BU14 and BU24 clamps ensure operational safety and consistent performance under pressure.
Inspect hoses and fittings for debris or damage.
Position the clamp evenly over the hose end.
Tighten bolts alternately to apply balanced pressure.
Avoid over-tightening, which can damage hoses.
Periodically check and retighten during high-vibration operation.
Store clamps in a dry environment to prevent rust.
Inspect bolts and clamp bodies regularly for wear.
Apply light lubrication on bolts for smooth operation.
Replace damaged components immediately to maintain sealing integrity.
| Parameter | BU14 | BU24 |
|---|---|---|
| Maximum Torque | 35 N·m | 45 N·m |
| Burst Pressure | 10 bar | 12 bar |
| Vibration Resistance | Moderate | High |
| Corrosion Test (Salt Spray 72 hrs) | Passed | Passed |
| Reusability | High | High |
This demonstrates their suitability for high-performance industrial air hose applications.
Q1. Are these clamps suitable for high-pressure air hoses?
Yes, BU24 can handle pressures up to 12 bar, and BU14 is suitable for medium-pressure applications.
Q2. Can Air Hose Boss Clamps be reused?
Yes. As long as there is no visible damage or thread wear, both BU14 and BU24 are reusable.
Q3. What hoses are compatible with these clamps?
They work with rubber, PVC, and reinforced air hoses that match the specified diameter ranges.
Q4. How do these clamps prevent hose slippage?
The precision-machined inner surface and double-bolt design ensure even clamping pressure.
Q5. Why choose ductile iron over stainless steel?
Ductile iron provides higher mechanical strength and impact resistance for industrial air hoses, making it cost-effective and durable for heavy-duty applications.
A construction equipment company upgraded its compressed air distribution network using Air Hose Boss Clamp BU24. Previously, standard steel clamps failed under high vibration, causing leaks. After installing BU24 ductile iron clamps, the system maintained airtight connections for over a year with minimal maintenance, demonstrating the reliability and durability of ductile iron clamps.
The Air Hose Boss Clamp BU14 and BU24 are essential components for modern industrial air hose systems. With their ductile iron construction, double-bolt design, and corrosion resistance, they provide long-lasting performance and reliable sealing.
These clamps are ideal for manufacturing, construction, agriculture, and automotive applications where pressure stability and durability are critical.
