Type HFSLA

Part of the SHIELD-FLEX® family of EMI/RFI Shielding conduits, as well as Zero-Halogen product family.

Type HFSLA is identical to standard UL Listed liquidtight flexible steel conduit (See Type LA) but is augmented with a tinned copper shielding braid located over the inner steel core and under its protective Polyurethane jacket. The braid offers a minimum of 90% coverage.

Type HFSLA liquidtight flexible shielding conduit is designed for field installations where safety concerns exist regarding a material’s reaction in a fire situation. The specially formulated thermoplastic polyurethane jacket has excellent flame retardancy and low smoke characteristics. Acidic gases such as hydrogen chloride, hydrogen fluoride and hydrogen bromide are virtually eliminated as products of combustion.

Construction:

Inner Core:

• Hot Dipped Galvanized Steel
• 3/8” – 1-1/4” Squarelock Profile with continuous bonding strip
• 1-1/2” – 2” Fully Interlocked Profile
• Shielded with a tinned copper braid

Liquidtight Jacket:

• Zero Halogen Polyurethane
• Resistant to Ozone, Hydrocarbons, Moderate Chemicals and Oils
• Flame Retardant
• Low Smoke
• Low Toxicity
• Sunlight Resistant (UV)

Application:

• Meets the requirements of Bombardier SMP 800-C for Toxic Gas Generation.
• Meets the requirements of both ASTM E162 for Flame Spread and ASTM E662 for Smoke Generation.

This conduit is intended for installation in accordance with Article 350 of the NEC (ANSI/NFPA-70)

• Suitable as an equipment grounding conductor per Article 250.118(6). Larger sizes require separate grounding conductor.
