A silicone coated heat sleeve is an essential protective solution for industrial hoses, cables, and wires exposed to high temperatures or harsh environments. Whether used in automotive, hydraulic, or foundry systems, this sleeve offers excellent thermal insulation, abrasion resistance, and long-term durability. At BSTFLEX, we manufacture premium silicone coated heat sleeves with inner diameters ranging from 4 mm to 150 mm, designed to provide reliable performance and long service life under extreme conditions.

What Is a Silicone Coated Heat Sleeve?

A silicone coated heat sleeve is made from woven fiberglass yarn that is coated with high-grade silicone rubber. The fiberglass base provides excellent heat resistance and strength, while the silicone coating adds a protective, flexible, and weatherproof outer layer. This combination creates a sleeve capable of withstanding continuous exposure to high temperatures, oil, and mechanical stress.

Typical continuous working temperature: 260°C (500°F)
Short-term resistance: up to 1000°C (1832°F) of radiant heat

Key Benefits

1. Exceptional Thermal Protection
The silicone coating reflects radiant heat and prevents heat damage to nearby components, maintaining safe operating temperatures for hoses and cables.

2. Superior Durability
Resistant to abrasion, chemicals, and oil contamination, this sleeve maintains its integrity even in demanding industrial and automotive environments.

3. Moisture and Flame Resistance
The silicone surface repels water and resists flame spread, making it ideal for applications where safety and reliability are critical.

4. Easy to Install and Flexible
The smooth outer layer allows easy sliding over hoses and cables, and its flexibility ensures a secure fit without cracking or fraying.

5. Extended Equipment Lifespan
By shielding hoses and wiring from thermal and mechanical stress, the silicone coated sleeve significantly reduces maintenance costs and downtime.

Installation Guide

1. Measure the hose or cable to determine the appropriate sleeve inner diameter (allowing a snug but flexible fit).

2. Cut the sleeve to the required length using scissors or a hot knife to prevent fraying.

3. Slide the sleeve over the hose or wire. If access is limited, you may use a split-type or self-closing version.

4. Secure both ends using stainless steel ties or heat-resistant clamps for a clean, professional finish.

5. Inspect regularly to ensure there is no excessive wear or contamination in high-motion areas.
