Mikalor Clamps

Mikalor Clamps: Heavy-Duty Solutions for Demanding Environments

Mikalor, a Spanish company with a history dating back to 1964, has established itself as a leading global manufacturer of high-quality clamping and fastening solutions. They are particularly renowned for their heavy-duty clamps, which are engineered to deliver "Hi-Grip" and "Hi-Torque" performance, making them the preferred choice for the most demanding industrial, automotive, marine, and agricultural applications. Mikalor's commitment to innovative design, robust manufacturing, and rigorous quality control ensures exceptional reliability and durability in critical connections.  

The Mikalor Advantage: Engineering for Extreme Performance

Mikalor's strength lies in its specialized product lines, which are meticulously designed to withstand challenging conditions where standard clamps often fail.  

1. Mikalor Supra Clamps (Single Bolt Heavy-Duty):

The Mikalor Supra clamp is a flagship product, often referred to as a bolt and barrel clamp, and is specifically designed for heavy-duty applications.  

• "Hi-Torque" & "Hi-Grip" Features:
• Revolutionary Swivelling Bridge: A unique design feature that allows the clamp to be mounted on hoses without having to remove the hose from the fitting. This ingenious "flip open front" facilitates easy installation in awkward or confined spaces, saving significant time and effort, especially on production lines or in complex assemblies.  
• High-Strength Bolt and Captive Nut/Spacer System: Mikalor designs and manufactures its own high-strength 8.8 grade steel bolts specifically for these clamps. This, combined with a captive nut and spacer system, allows for the application of very high tightening torques, ensuring extreme clamping force without damaging the components. This robust system provides a secure, leak-tight seal even on high-pressure hoses.  
• Bevelled Edges: The band features carefully bevelled edges that protect the hose from damage or cutting during tightening, enhancing the longevity of the hose itself and the integrity of the connection.  
• Uniform Pressure Distribution: The design ensures an even clamping pressure around the entire circumference of the hose, crucial for sealing highly pressurized hoses or pipes, especially those functioning at high temperatures (like exhaust pipes and coolant/turbo hoses).  

2. Mikalor ASFA Clamps (Worm Drive):

Mikalor offers a wide range of worm drive clamps under its ASFA brand (ASFA-L, ASFA-S, ASFA High Torque). These are high-quality worm drive clamps designed to DIN 3017 standards.  

• "Hi-Grip" & Enhanced Performance Features:
• Non-Perforated or Embossed Band (ASFA High Torque): Mikalor pioneered the ASFA High Torque clamp, a 16mm worm drive hose clamp that stands out due to its non-perforated or embossed band. This design provides superior strength and eliminates the possibility of the band cutting into softer hoses, offering high strength and a high-quality solution.  
• Optimized Design and Housing: The ASFA-S (12mm band) series, for instance, features an optimized housing design that allows for efficient installation and reduces lateral movement during tightening, increasing pressure capacity.  
• Precision Rolled Threads: Ensures a strong, smooth engagement with the screw, facilitating precise tightening and preventing thread stripping, even under higher torques.

3. Mikalor Super Clamps (Another Heavy-Duty Variant):

The Mikalor Super Clamp was one of the first heavy-duty clamps of its kind on the market, and it remains a robust solution.  

• High Strength: Equipped with an 8.8 grade steel nut and T-bolt for easy tightening with a wide range of tools, providing excellent crush strength.  
• Hose Protection: Designed with bevelled edges to protect the hose from damage.  

Materials and Corrosion Resistance

Mikalor understands that demanding environments require superior material integrity. Their clamps are available in various material grades to suit specific corrosive conditions:  

• Mild Steel (W1 - Zinc Plated Steel): Suitable for general-purpose applications where moderate corrosion resistance is required.
• Ferritic Stainless Steel (W2 - AISI 430 Stainless Steel with Zinc Plated Bolt): Offers enhanced corrosion resistance compared to W1, often used in applications exposed to some moisture.
• Austenitic Stainless Steel (W4 - AISI 304 Stainless Steel): The most common choice for industrial, automotive, and marine applications requiring good corrosion resistance.
• High-Grade Austenitic Stainless Steel (W5 - AISI 316 Stainless Steel): Provides the highest level of corrosion resistance, especially against saltwater, acids, alkalis, and other aggressive chemicals. This is the preferred material for marine, food, pharmaceutical, and petrochemical industries.
• Titanium (ASFA-S Titanium): For extremely demanding applications where ultimate corrosion resistance and light weight are critical (e.g., offshore, aeronautics, chemical industries involving acids).

Applications for Demanding Environments

Mikalor clamps are engineered to perform in scenarios where reliability is non-negotiable:

• Automotive Industry (Performance & Heavy-Duty): Critical for securing exhaust systems, turbocharger connections, intercooler hoses, high-pressure coolant lines, and air intake systems in performance vehicles, heavy trucks, buses, and construction machinery. The Supra's ability to handle high temperatures and pressures is a key benefit here.
• Marine Industry: Essential for below-the-waterline applications, engine cooling systems, exhaust hoses, and other fluid transfer lines exposed to harsh saltwater and corrosive elements. The W4 and especially W5 stainless steel grades are vital in this sector.
• Agricultural Machinery: Securing various hoses in tractors, harvesters, and other heavy farm equipment that operate in dirty, wet, and vibratory conditions.  
• Industrial Hydraulics & Pneumatics: Used in high-pressure hydraulic lines, pneumatic systems, and industrial fluid transfer where robust and leak-proof connections are essential for operational safety and efficiency.  
• Mining & Quarrying: For heavy-duty hoses in extraction and processing equipment, where resistance to abrasion, extreme loads, and harsh environments is paramount.
• Food & Beverage Processing / Pharmaceutical: 316 stainless steel clamps are specified for these industries due to their hygienic properties, non-corrosive nature, and resistance to strong cleaning agents.  
• Wastewater Extraction: Securing large diameter hoses in pumps and filtration systems.
• General Engineering: Whenever a robust, reliable, and durable clamping solution is required for high-pressure, high-temperature, or corrosive environments.  

Why Choose Mikalor Clamps?

• Unmatched Strength and Durability: Mikalor's proprietary designs, particularly the Supra and ASFA Hi-Torque, provide significantly higher clamping force and breaking torque than conventional clamps.
