12an HS79/ProPlus Crimp Collar - Super Nickel

The 12AN HS79/ProPlus Crimp Collar in Super Nickel finish is a precision hydraulic hose fitting component designed for high-performance fuel systems, coolant lines, and pressurized fluid transfer in custom automotive builds. This compact crimp collar serves as the foundational sealing element in hose assembly, ensuring leak-free connections under extreme pressure and temperature fluctuations. Whether you're fabricating custom fuel injection systems, turbo coolant loops, or transmission cooler lines, this fitting demands the same attention to detail and quality that separates a reliable modification from a catastrophic failure.

Engineered to HS79 and ProPlus standards, this crimp collar features Super Nickel plating—a corrosion-resistant coating that outperforms standard zinc in salt-spray and moisture-heavy environments. The 12AN (AN12) size accommodates 12/16-inch nominal hose, supporting SAE J518 compatibility across OEM and aftermarket hydraulic systems. The crimp collar's design allows proper ferrule seating and hose compression, creating a hermetic seal that withstands sustained pressures without weeping or degradation. Its compact profile (1.95 x 1.25 x 2.65 inches) and lightweight construction (0.03 lbs) make integration seamless in tight engine bays and chassis applications.

This fitting benefits technicians and fabricators working on fuel system upgrades, supercharger/turbo cooling systems, hydraulic brake conversions, and street/race engine builds requiring industrial-grade reliability. Proper installation requires correct hose sizing, ferrule selection, and crimp tool calibration—common oversights that lead to system failure in high-vibration or high-heat environments. The 12AN HS79/ProPlus Crimp Collar pairs with matching hose, ferrules, and end adapters to create verified leak-free assemblies. Stock this component for any serious modification shop focused on durability over compromise.
