MIL-W-5664 Type I elastic nylon webbing

The MIL-W-5664 specification, also associated with PIA-W-5664, covers woven elastic nylon webbing.
The construction combines high-tenacity Nylon 6.6 yarns with an elastic core or elastomeric elements to provide controlled extension and recovery.

Technical characteristics

Controlled elasticity: Designed to provide repeatable extension and return force according to the product configuration.
Protective outer yarns: Nylon protects the elastic elements against abrasion and repeated handling.
Durability: Construction is intended for repeated extension cycles in military and aerospace equipment.

Typical applications

• aviation oxygen-mask retention,
• flight-helmet chin or retention straps,
• elastic tactical equipment retention,
• comfort and adjustment zones in technical clothing,
• equipment and accessory holding systems.

  MIL-W-5664 vs MIL-W-17337

  MIL-W-17337 is a rigid flat tactical webbing for fixed attachment systems. MIL-W-5664 is used where elastic retention and controlled extension are required.
