Yellow Jacket 21986 Charging Hose Set

The Yellow Jacket 21986 Plus II is a professional-grade HVAC charging hose set engineered for high-pressure performance in the field. This three-pack includes 72-inch red, yellow, and blue hoses, each featuring a 1/4" flare fitting compatible with standard manifold gauge sets. Designed to meet the demands of modern systems, these hoses utilize a double barrier protection system with a nylon permeation barrier that complies with SAE J2196 requirements. This construction effectively contains the smaller molecules of newer refrigerants, including R-410A, while providing a moisture barrier that prevents contamination of expensive systems. Built for durability, these hoses are rated for a 4,000 PSI burst pressure and an 800 PSI working pressure, maintaining structural integrity across an operating temperature range of -20° to 180°F. For contractors working in confined service panels, the 6-inch minimum bend radius ensures flexibility without kinking, maintaining consistent flow during recovery or charging procedures. These premium refrigeration hoses are UL-recognized assemblies, ensuring safety and compliance on every job site.

• R-410A Compatibility: High-pressure rating of 800 PSI working pressure specifically handles the demands of R-410A and other high-pressure HVAC systems.
• Permeation Resistance: Integrated nylon barrier reduces refrigerant loss and meets strict SAE J2196 standards for HFC, HCFC, and CFC gases.
• Moisture Protection: Advanced moisture barrier prevents ambient humidity from migrating into the hose and contaminating system oil.
• Field-Proven Durability: 4,000 PSI burst pressure rating provides a high safety margin for technicians during high-load charging cycles.
• Standard Fitment: Equipped with standard 1/4" flare fittings for seamless integration with most 1/4" charging and recovery equipment.

Are these hoses safe for use with R-410A systems?
Yes, the Yellow Jacket 21986 is specifically rated for 800 PSI working pressure and 4,000 PSI burst pressure, making it fully approved for high-pressure R-410A applications.

What is the benefit of the double barrier protection?
The double barrier includes a nylon permeation layer that stays flexible while preventing the escape of refrigerant molecules, which is critical when working with newer HFC refrigerants that tend to permeate standard rubber hoses more easily.

Will these hoses fit my standard 5/16" R-410A mini-split ports?
These hoses feature 1/4" flare fittings. To connect to 5/16" mini-split service ports, a separate 1/4" to 5/16" adapter is required, or you may utilize the optional FlexFlow assemblies for restricted access areas.
