What is a Fire Sleeve?

A fire sleeve is a protective covering designed to shield hoses, cables, and wires from extreme heat, flames, and other harsh environmental conditions. Constructed from materials that offer high-temperature resistance, fire sleeves are essential in industrial, automotive, and aerospace applications where exposure to high heat and flames is common.

Sizes of Fire Sleeves

Fire sleeves come in a variety of sizes to accommodate different applications:

• Inner Diameter (ID): Typically ranges from 1/8 inch to 4 inches, allowing for a snug fit around various hoses and cables.
• Wall Thickness: Can vary from 1/16 inch to 1/4 inch, depending on the level of protection required.

Colors of Fire Sleeves

Fire sleeves are available in multiple colors, including:

• Black: The most common color, often used for standard applications.
• Red: Used for high-visibility applications.
• Orange: Often chosen for its visibility in emergency situations.
• Other Custom Colors: Available upon request to meet specific needs or aesthetic requirements.

Types of Fire Sleeves

1. Fire Sleeve with Velcro:

   • Description: Equipped with Velcro closures for easy installation and removal.
   • Use Case: Ideal for applications where frequent access to the protected hoses or cables is necessary.

2. Fire Sleeve with Snap:

   • Description: Features snap fasteners for secure and easy attachment.
   • Use Case: Suitable for applications requiring a more robust and secure fastening method.

3. Inside Basalt Fire Sleeve:

   • Description: Made from basalt fibers, offering superior heat resistance and durability.
   • Use Case: Preferred in high-temperature environments where exceptional protection is required.

Certifications

Fire sleeves may come with various certifications to ensure their effectiveness and safety, including:

• UL (Underwriters Laboratories): Certifies that the fire sleeve meets specific safety and performance standards.
• ISO (International Organization for Standardization): Indicates compliance with international standards for quality and performance.
• ASTM (American Society for Testing and Materials): Ensures that the fire sleeve meets ASTM standards for heat resistance and durability.

Additional Information

• Material Composition: Common materials include silicone, fiberglass, and basalt, each offering varying degrees of heat resistance and flexibility.
• Temperature Resistance: Fire sleeves can typically withstand temperatures ranging from 300°F (150°C) to over 2000°F (1100°C), depending on the material.
• Applications: Used in automotive engines, aerospace, industrial machinery, and anywhere else where heat protection is critical.

Fire sleeves are essential components in maintaining safety and functionality in high-temperature environments. Their availability in various sizes, colors, and types, combined with rigorous certification standards, ensures they meet the diverse needs of different industries.
