SPIFR #8 Metal Fire Retardant Open End (O/E) Zipper

Core Selling Points

#8 Heavy-Gauge Metal Chain for Maximum Load Capacity
Built with a robust #8 metal gauge, the zipper withstands high tensile loads, repeated heavy pulling, and continuous stress from thick garment structures. The larger tooth profile enhances durability for industrial jackets, protective outerwear, and rugged work gear.

Open-End Construction for Full Separation
The Open End (O/E) system allows the zipper halves to separate completely at the bottom, making it suitable for jackets, industrial protective coats, tactical over-garments, and multi-layer systems requiring fast on/off functionality. The box and pin are reinforced to resist deformation from repeated use.

Fire-Retardant Metal Components for High-Risk Work Zones
All metal elements—including teeth, slider, pin, and bottom box—are processed for fire-retardant performance, helping reduce ignition and flame spread. Ideal for applications in welding, aerospace, oil & gas environments, electrical utility work, and emergency response operations.

Stable Tooth Alignment Under Heavy Movement
The chain maintains consistent alignment during bending, twisting, torso rotation, or movement caused by equipment load. This stability minimizes the risk of tooth distortion, chain warping, or slider jamming in demanding work conditions.

Smooth Slider Performance on Thick, Multi-Layer Fabrics
The zipper operates cleanly on FR textiles, laminated protective materials, industrial canvas, insulated outerwear, and coated fabrics. Performance remains reliable even with gloves, contamination from dust or oil, or exposure to low temperatures.

High Resistance to Abrasion, Impact, and Chemicals
The structure tolerates friction from harnesses, belts, and protective gear, impacts from tools, and exposure to oils, lubricants, debris, and outdoor elements. Ideal for harsh environments where garments face unpredictable stress.

Reinforced Bottom Mechanism for Long-Term Durability
The O/E box and pin system is strengthened for repetitive high-force use. This reinforcement helps prevent accidental disengagement and supports long-term reliability in jackets used for industrial or tactical purposes.

Versatile Application Across Heavy-Duty Garment Systems
Suitable for fire-resistant jackets, industrial safety outerwear, tactical and paramilitary coats, insulated protective gear, motorcycle outerwear, and work-at-height or rescue uniforms.

OEM Customization for Uniform Manufacturing Programs
Custom options include length, tape width, FR tape materials, matte or anti-corrosion metal finishes, reinforced or glove-grip puller designs, uniform color matching, and upgraded box/pin assemblies for heavy-frequency operation.
