FlameShield high temperature and heat resistant Kevlar aramid sleeve is fabricated from high quality yarns that will not burn and will withstand continuous exposure to temperatures of 320°F / 160°C. It provides excellent protection for industrial wires, cables, hoses (hydraulics), tube and pipes and also provides thermal insulation and personnel protection.  Kevlar is highly cut resistant, making this sleeve especially suited where contact with sharp edges is a concern.

This sleeve is available in:

  • Standard Wall - natural (yellow)
  • Heavy Duty Wall - natural (yellow)
  • Medium Wall - colored (Safety Orange, Black, Blue, Red, Green, Yellow (natural))

This high temperature sleeve / heat resistant sleeve resists most acids and alkalis and is unaffected by most bleaches and solvents. The Standard sleeve is highly flexible and conformable while the Heavy Duty version is stiffer but still very flexible.

Both sleeves do experience end fray when cut as there is no binder present in the sleeve; there are several methods of reducing the fray: please visit our FAQ section for further information.

Silicone Rubber Round Tubing

Silicone Rubber Round Tubing / Sleeving - Oxide-Red High Temperature Heat Chemical Resistant


460°F / 237°C Continuous Exposure: Higher Intermittent

We offer several versions of silicone rubber tubing/sleeving:  Natural/Clear in small sizes, Oxide-Red in a mid-range of sizes, Oxide-Red large size, Star tubing for fastener thread protection, and food grade FDA tubing.

Our high temperature silicone rubber tubing is manufactured to exacting standards from our formulation of high-temperature silicone.  Industrial Silicone Tubing is used commonly to convey and transfer liquids, air or gases and to protect wires and hoses from high temperature environments.

High temperature silicone rubber tubing can also be used as a mask to protect bolt and screw threads in painting and powder coating operations, and due to the high temperature rating, can often be reused multiple times.

Due to the non-stick characteristics of silicone rubber, molten metal, weld splatter and grinding sparks do not stick to the silicone tubing.


Insulated Sleeve Wrap for Steam Pipe and Hose - Thermal Insulating - OSHA Burn Protection


500°F / 260°C High Temperature Heat Resistant Thermal Insulating - Also Freeze Protection

Custom fabricated insulated wrapping tape for pipe, hose and line protection: high temperature protection and cold temperature protection.  Excellent thermal protection and energy saving for boiler piping and steam pipe applications.  Also provides thermal insulation and protection to flexible hoses and lines, and rigid lines and piping.  Provides personnel burn protection to meet OSHA requirements.

The outer cover is a 32oz/yd2 silicone rubber coated fiberglass.  This outer fabric can also be supplied meeting NRC 1.36 specifications.  The insulation layer and outer protection layer also meets MIL-I-24244 specifications.

The insulation layer is can be either 1/4", 1/2" or 3/4" thick fiberglass. The 3/4" thickness is a combination of 1/4" and 1/2" insulation layered and stitched.

An optional liner of PTFE coated fiberglass fabric provides additional protection of the insulation layer, especially useful if the tape will be removed and re-installed multiple times, or to prevent wear of the needled insulation and reducing the fibers from becoming free in the area of use.  This insulated pipe and hose wrap tape is sewn with high temperature fiberglass thread.  A hook and loop fastener is added on the edges of the tape, allowing for easy closure and removal - allowing for easy inspection of the underlying hose, line or piping. The standard hook and loop is nylon; nomex and stainless steel closure versions are available.

May be installed longitudinally or spirally over pipes, hoses, wires and cables.

Supplied in 20 foot lengths. May be cut in the field to shorter lengths.

Fiberglass braided sleeve with soft PTFE coating

Fiberglass Braided Sleeve with soft PTFE dispersion infusion


550°F / 287°C Continuous Exposure: Higher Intermittent

FlameShieldä This high temperature, heat / chemical resistant and thermal insulating PTFE coated fiberglass sleeve offers the advantage of a non-asbestos material with a higher temperature range and with excellent resistance to almost all solvents, caustics and acids.

The base fiberglass fabric is rated to 1000°F / 537°C while the PTFE coating melting point is 620°F / 327°C.

Available in 1/16" (thin wall) and 1/8" (thick wall) wall thickness.

Inside Diameters available from 0.25" up to 5.0".

The PTFE is applied to the sleeve by dipping the sleeve through an immersion tank of liquid PTFE dispersion.  The sleeve is then air dried and high temperature sinterized, flowing the PTFE throughout the fiberglass filaments.  The result is a PTFE coating on the sleeve which is soft, robust and flexible; however, it can be abrasively removed from the sleeve with aggressive fingernail scraping, resulting in a thinner and thinner layer of ptfe remaining with each pass.  The coating process also causes the yarns to be sealed and the small gaps between the yarns filled, resulting in an almost air-tight / liquid-tight sleeve wall.
