Yellow Jacket 21984 Charging Hose Set

Engineered for the rigorous demands of modern field service, the Yellow Jacket 21984 PLUS II Charging Hose Set offers high-performance fluid handling for technicians working with R-410A, HFC, and HFO refrigerants. These 48-inch HVAC charging hoses feature a advanced double barrier protection system: a nylon permeation barrier that meets SAE J2196 requirements and a moisture barrier to prevent contamination of expensive refrigerant. With a 800 PSI working pressure and a 4000 PSI burst pressure rating, these hoses handle high-pressure systems with professional-grade safety. The 1/4" refrigerant hose fittings are built with deep knurling for a secure grip, ensuring a leak-proof seal on your manifold gauge set even when hands are oily. Designed to withstand extreme environments, they maintain flexibility in temperatures ranging from -20° to 180°F. This 3-pack (Red, Yellow, Blue) is the benchmark for contractors who prioritize leak-free HVAC service and internal hose integrity over multiple seasons of heavy use.

• High-Pressure Capability: Rated for 800 PSI working pressure and 4,000 PSI burst pressure, making them ideal for high-pressure R-410A system charging.
• UL Recognized Assemblies: Every hose in this set is UL recognized (File SA9737), ensuring compliance with industry safety standards.
• Contamination Resistance: The integrated moisture barrier prevents ambient humidity from migrating into the system, protecting the compressor and oil.
• Chemical Compatibility: The internal nylon barrier is compatible with all standard CFC, HCFC, HFC, and HFO refrigerants.
• Maximum Flexibility: Features a 6-inch minimum bending radius for easy maneuverability in tight condenser cabinets and equipment rooms.

Are these hoses compatible with R-410A systems?
Yes, the Yellow Jacket 21984 set is specifically engineered for high-pressure refrigerants like R-410A, featuring a 800 PSI working pressure rating that far exceeds standard manifold requirements.

Do these hoses include a shut-off valve?
This specific model features standard 1/4" HAV fittings without built-in ball valves. For low-loss disconnection, many technicians pair these with Yellow Jacket 18975 or 19302 compact ball valves.

What is the benefit of the Plus II double barrier?
The double barrier is essential for newer HFC and HFO blends. It prevents the smaller molecules of these refrigerants from permeating the hose wall and keeps moisture out, which is critical for systems using hygroscopic POE oils.
