A/C Hose End Kit

The A/C Hose End Kit (MPN 417) is an essential component for anyone servicing or upgrading their vehicle's air conditioning system. Whether you're performing routine maintenance, replacing a failed compressor, or custom-building a performance cooling setup, this hose end kit provides the connection hardware needed to properly terminate refrigerant lines. Mechanics and enthusiasts rely on quality hose fittings to ensure leak-free seals that maintain system pressure and cooling efficiency.

This kit contains precision-engineered hose ends designed to crimp or swage onto aluminum or rubber A/C lines, creating a permanent, pressure-rated connection that withstands the thermal cycling and vibration demands of modern climate control systems. The compact design—measuring 3.15 x 3.05 x 3.4 inches and weighing just 0.34 lbs—fits easily in a toolbox or service cart. Each fitting is manufactured to exacting tolerances to ensure compatibility with standard SAE flange connections, critical for maintaining system integrity and preventing refrigerant escape or moisture ingress that can compromise compressor longevity.

This hose end kit is ideal for custom A/C system builds, performance engine swaps, and professional shop repairs where factory hose assemblies don't fit tight engine bays or modified configurations. Whether you're fabricating lines for a classic car restoration, updating a turbocharged engine's cooling capacity, or replacing damaged factory fittings, the A/C Hose End Kit delivers the quality and fit that keeps your system running cool and reliable. Installation requires basic crimping tools and knowledge of proper flare or swage techniques—skills any serious DIY mechanic or professional technician should possess.
