Langina 32pc AC Hose & Fitting Kit — 3 Hose Sizes (5/16, 13/32, 1/2), Aluminum Elbows & R134a Ports

This kit brings together three sizes of high-pressure hoses, a broad assortment of 45°, 90° and 180° aluminum elbows, and dedicated R134a service-port fittings—packaged in a rugged portable toolbox. It’s intended for mechanics, restorers, and DIY enthusiasts who need reliable, crimpable connections for classic car restorations, engine swaps, or heavy-duty truck AC repairs. Every part is labelled for fast selection and engineered to meet demanding temperature and pressure conditions.

How does this kit handle different vehicle hose routing challenges?

The kit’s variety of elbow angles and three hose diameters solves tight routing problems and simplifies custom line fabrication. Elbow choices let you route around headers, radiators, or compression points without awkward bends that restrict flow.

• Includes 8 each of 45°, 90° and 180° elbows for versatile routing.
• Three hose inner diameters—5/16", 13/32", and 1/2"—cover common system sizes.
• Labelled fittings speed identification in confined engine bays.

What performance and durability can I expect from the hoses and fittings?

Hoses are built for workshop and road conditions with a 650 PSI working pressure rating and a wide temperature tolerance. The aluminum fittings are machined for consistent crimp profiles that form long-lasting, leak-resistant joints when used with standard hydraulic crimpers.

• 650 PSI working pressure and -4°F to 212°F temperature range.
• Aluminum fittings with smooth bore to reduce flow restriction.
• Dual-seal crimp design grips liner and compresses sleeve for longevity.

Can I use this kit for vintage AC conversions to modern refrigerants?

Yes—the set includes R134a high/low pressure service port fittings that let you update older R12 systems to R134a or build new systems compatible with modern refrigerants. The fittings allow professional-style service access without cutting corners on reliability.

• Four fittings include R134a high/low service ports for modern refrigerant access.
• Crimp-ready design supports professional conversion workflows.
• Clear labelling and variety help match original routing or create factory-like upgrades.

What makes the packaging and organization useful for mechanics?

The kit ships in a heavy-duty black toolbox divided into size-specific compartments so fittings and hoses remain protected and easy to find. The case doubles as long-term storage for other workshop items once the AC job is finished.

• Rigid portable toolbox with three organized compartments for quick access.
• Protects components from impacts, moisture, and contamination.
• Reusable for sockets, wrenches, or future AC parts storage.

Who is this for: Langina’s 32-piece AC Hose and Fitting Kit is built for automotive technicians, restoration enthusiasts, hot rod builders, and fleet maintenance professionals who need a full set of crimpable fittings and multiple hose sizes to fabricate durable, leak-resistant AC lines. It’s particularly suited to projects where precise routing, serviceability, and long-term pressure integrity matter—such as classic car AC conversions, LS engine swaps, and heavy truck system repairs.
