What Are Fire Rated Sleeves: The Ultimate Guide to Fire Sleeving 2023

Table of Contents


Fire safety is a critical consideration in any building or structure. The implementation of effective fire protection measures is essential to safeguard lives and property in the event of a fire. One crucial component in fire safety systems is fire-rated sleeves.

In this article, we will explore what fire rated sleeves are, how they work, their importance, and much more.

What Are Fire Rated Sleeves?

Fire rated sleeves are fire-resistant enclosures that surround penetrations, such as cables, pipes, or ducts, passing through fire-rated walls or floors. These sleeves are constructed using fire-resistant materials and are designed to maintain the integrity of fire barriers, preventing the spread of flames, heat, and smoke.

Importance of Fire Rated Sleeves

Fire rated sleeves play a crucial role in maintaining the fire resistance of walls and floors. They create a barrier that prevents fire from spreading from one compartment to another, providing valuable time for occupants to evacuate safely and for emergency responders to contain the fire.

By sealing penetrations, fire rated cable sleeve can help limit the passage of smoke and toxic gases, reducing the risk of inhalation and aiding the overall fire safety strategy.

How Fire Rated Sleeves Work

Fire rated sleeves work by combining various fire-resistant materials to form a protective barrier around penetrations. These materials can include intumescent compounds, fire-resistant foam, or metallic sheaths. In the event of a fire, the fire rated cable sleeve expands or solidifies to seal the opening and prevent the spread of fire and smoke.

Common Applications of Fire Rated Sleeves

Fire rated sleeves find applications in various industries and settings. Some common applications include:

Commercial Buildings

In commercial buildings, fire rated cable sleeves are used to seal penetrations created by electrical cables, data cables, plumbing pipes, and HVAC ducts. They are essential in maintaining the fire compartmentalization required by building codes and regulations.

Industrial Facilities

Industrial facilities often have complex systems involving numerous penetrations. Fire rated sleeves are used to seal these penetrations, ensuring that fire and smoke do not spread between different areas of the facility.

Residential Construction

In residential construction, fire rated sleeves are installed around penetrations in walls and floors, such as electrical cables and plumbing pipes. This helps to minimize the risk of fire spread within the building.

Types of Fire-Rated Sleeves

Fire rated sleeves come in different types, each designed to meet specific requirements and fire safety standards. The two common types of fire rated sleeves are:

Metallic Fire Rated Sleeves

Metallic fire rated sleeves are typically constructed using stainless steel or galvanized steel. They provide excellent fire resistance and are known for their durability and strength. Metallic sleeves are often used in high-impact areas or where mechanical protection is required.

Fire Sleeve for Hydraulic Hose

Fire sleeves for hydraulic hoses are protective coverings designed to withstand high temperatures and provide an additional layer of safety.

They are typically made from flame-resistant materials, such as silicone, fiberglass, or aramid fibers, which offer excellent resistance to heat and flames. By covering hydraulic hoses with fire sleeves, the risk of fire incidents caused by heat exposure is significantly reduced.

Fire Rated Conduit Sleeve

Fire rated conduit sleeves are specialized components designed to protect electrical conduits by preventing the spread of fire, heat, and smoke through them. They are typically made of fire-resistant materials that can withstand high temperatures and maintain their structural integrity during a fire.

By incorporating fire rated conduit sleeves into electrical systems, the risk of fire propagation through conduits is significantly reduced.

Fire Rated Sleeves for Cables

Fire rated sleeves for cables are specialized components designed to prevent the spread of fire and smoke through cable penetrations in walls, floors, or ceilings.

They are constructed from fire-resistant materials, such as intumescent compounds or mineral fibers, which expand when exposed to high temperatures, creating a barrier that restricts the passage of flames and smoke.

Aeroquip Fire Sleeve

The Aeroquip Fire Sleeve is constructed using a combination of high-temperature resistant materials, such as silicone-coated fiberglass, to provide exceptional heat resistance and thermal hydraulic hose insulation.

This silicone-coated fire sleeve acts as a barrier between the hydraulic hose and external heat sources, preventing direct contact and shielding the hose from potential sparks or flames.

The key benefits of using the Aeroquip Fire Sleeve include:

  1. Heat resistance: The Aeroquip Fire Sleeve is designed to withstand high temperatures, protecting hydraulic hoses from heat-related damage and maintaining their integrity even in extreme operating conditions.
  2. Flame protection: The sleeve’s construction materials offer excellent resistance to flames, reducing the risk of fire incidents caused by heat exposure.
  3. Abrasion resistance: In addition to heat protection, the Aeroquip Fire Sleeve provides a layer of defense against abrasion, shielding hydraulic hoses from wear and tear caused by contact with rough surfaces or other components.
  4. Easy installation: The Aeroquip Fire Sleeve is designed for easy installation. It can be slipped over the hydraulic hose and secured in place using clamps or ties, ensuring a secure fit and optimal protection.
  5. Compatibility: The Aeroquip Fire Sleeve is available in various sizes to accommodate different types and sizes of hydraulic hoses, making it highly versatile and compatible with a range of applications.

When selecting the Aeroquip Fire Sleeve, it is essential to consider the temperature rating and size compatibility to ensure optimal protection for the hydraulic system. The sleeve should be chosen based on the maximum operating temperature of the hydraulic system and the diameter of the hose it will be used with.

Proper installation of the Aeroquip Fire Sleeve is crucial to ensure its effectiveness. It should be securely fastened and positioned to cover the entire length of the hydraulic hose, leaving no exposed areas vulnerable to heat or flames.

Choosing the Right Fire Rated Sleeves
