A/C Accessories

Alamo stocks hose adapters and fittings, dye injector kits, UV leak-detection lights, manifold gauge adapters, vacuum pump oil, refrigerant-identifier accessories, and system-flushing equipment for R-134a and R-1234yf automotive A/C service. Most accessories are designed to work with professional shop-grade service machines.

Many accessories are refrigerant-specific due to differing fitting standards and contamination risks across refrigerant types. R-1234yf fittings use a different quick-connect design than R-134a to prevent cross-contamination. Always verify refrigerant compatibility before purchasing an adapter or coupling.

UV dye is injected into the A/C system and circulates with the refrigerant. When a leak is present, dye escapes and is visible under UV light as a bright green or yellow glow at the leak point. UV dye detection is especially useful for small leaks that are not detectable by electronic leak detectors.

Vacuum pump oil absorbs moisture during refrigerant evacuation cycles. Contaminated oil reduces pump efficiency and can cause damage over time. Most manufacturers recommend changing the vacuum pump oil every 10 to 20 service cycles or whenever the oil becomes discolored. Using the correct viscosity grade is important for maintaining pump vacuum depth.

Some accessories are universal (UV light kits, vacuum pump oil) while others are brand or platform-specific (hose adapter kits, charging station fittings). Always verify compatibility with your specific A/C service machine brand and model before purchasing adapters or fittings.

A/C system flushing removes contaminated refrigerant oil, debris, and contaminants from the system when a compressor failure has scattered metal particles or when refrigerant oil has severely degraded.
Flushing is required before installing a new compressor to prevent premature failure from circulating contaminants.

Most accessories in this collection are designed for professional automotive shop use. Refrigerant handling equipment for R-1234yf and R-134a requires EPA Section 609 certification for technicians who purchase refrigerants. Accessories such as UV kits, adapters, and pump oils do not require certification individually but are intended for trained shop technicians.
