SPIFR #5 Metal Fire Retardant Two Way Open Zipper

Features

Proven Flame-Resistant Construction

Independent laboratory testing confirms that the zipper’s FR tape and metal components do not ignite, melt, drip, or separate when exposed to elevated temperatures. The assembly retains full functionality under thermal stress, ensuring safe and reliable operation in high-risk environments.

Exceptional Material Stability

The zipper demonstrates very minimal carbonization under flame exposure—an indicator of strong heat resistance and structural integrity. This performance exceeds typical baseline requirements for FR garment components and supports long-term durability in demanding industrial applications.

Fully Functional After Heat Exposure

Even following prolonged thermal contact, the zipper maintains smooth slider movement and consistent engagement between metal teeth. This ensures that garments remain operational during and after exposure to heat, a critical factor for emergency response and industrial safety gear.

Two-Way Open-End System for Professional Use

The dual-slider design allows both top-down and bottom-up operation, ideal for ventilation control, rapid access, equipment reach, or emergency doffing. The open-end structure supports full separation of the garment front, essential for jackets, suits, and outerwear requiring quick removal.

Robust Metal Chain for High Durability

The #5 metal chain delivers strong mechanical performance with excellent resistance to abrasion, impact, and repeated cycling. The teeth remain stable without deformation, further reinforced by the zipper’s proven heat resistance.

Suitable for Certified FR Garment Systems

With verified performance that meets common expectations for flame-resistant garment components—such as no ignition, no melting/dripping, controlled char behavior, and retained functionality—this zipper is suitable for integration into:

• FR coveralls & workwear

• Fire-resistant jackets

• Flight suits & pilot uniforms

• Tactical and emergency response gear

• Petrochemical & electrical utility PPE

• Welding and metalworking apparel
