Air Conditioning (A/C) Fittings & Hoses

Professional Climate Control for Performance & Custom Builds

Integrating a reliable air conditioning system into a performance car or engine swap requires specialized hardware that can handle unique chemical refrigerants and high pressure. At AN Fittings NZ, our Air Conditioning collection is engineered to provide a leak-free, long-term solution. Because A/C systems use gases like R134a, they require specialized Barrier Hose—a multi-layer hose designed specifically to prevent gas permeation.

Whether you are restoring a classic with a custom A/C loop or plumbing a modern engine swap, our range provides the professional components needed to ensure ice-cold performance and environmental safety.

Specialized Hardware for Refrigerant Systems

Air conditioning plumbing relies on specific sealing surfaces and hose construction that differ from standard oil or fuel systems:

  • A/C Barrier Hose: This is a specialized, industry-standard hose featuring a nylon inner liner. This "barrier" is essential to contain small-molecule refrigerant gases that would otherwise leak through standard rubber or braided hoses.

  • Speedflow A/C Fittings: We stock specialized Speedflow aluminum fittings designed specifically for A/C applications. These feature the correct O-ring seats and are designed to be crimped onto barrier hoses for a permanent, gas-tight seal.

  • O-Ring Sealing Technology: Most A/C compressors and condensers use specialized O-ring connections. Our range includes the adapters needed to transition from your OEM components into a custom-routed hose setup.

  • Charge Ports & Service Valves: Essential for system maintenance. We provide high and low-side service ports that allow professional technicians to charge and test your system safely.

  • Compact Routing Solutions: A/C systems are often an afterthought in tight engine bays. We offer a variety of 45° and 90° fittings to help you route lines neatly around turbos, radiators, and suspension towers.

Reliability for the NZ Street & Show Scene

In the New Zealand summer, a functional A/C system makes a performance car truly driveable. We understand that a "near enough" approach doesn't work with refrigerant—one tiny leak and the system is useless. That’s why we provide the high-quality fittings and correct barrier hose required for a "fit and forget" installation.
