Why Black Knight
Mobile A/C ready.
R-1234YF adapters included.
Forged brass body.
The HCPRO Black Knight Mobile A/C manifold is the professional-grade tool for R-1234YF vehicle service — forged brass body, Class 1.6 calibrated gauges pre-calibrated for R-1234YF, Dual Force premium black hoses, AND included R-1234YF high-side + low-side quick-connect adapters. Built for dealership service writers, mobile A/C shops, and hybrid/EV specialists working with R-1234YF on 2015-and-newer vehicles.
Forged brass body, no shortcuts
Heavy-duty forged brass 2-valve manifold body — the professional service standard for charging, evacuation, and diagnostics. No-leak neoprene O-ring system, easy-grip hex handles. Built for the rough handling of daily service truck use — drops, vibration, temperature swings. Smooth piston-type valves give you precision control on charging and recovery without the chatter of cheap stamped-brass bodies.
3-1/8″ Class 1.6 R-1234YF calibrated gauges
Large 3-1/8″ (80mm) analog gauges with Class 1.6 accuracy and dual-scale °F/PSI readings, pre-calibrated for R-1234YF — the dominant refrigerant in vehicles built from 2015 forward (HFO-1234yf, replacing R-134a for environmental regulation compliance). Shock-proof rubber covers protect against drops.
Dual Force premium black hoses
Standard 3-hose set — HCPRO Dual Force premium black hoses with color-coded indicator lines (red high, blue low, yellow service / vacuum). The Dual Force jacket is the HCPRO professional hose technology — premium black braided construction reads clean on the truck and on the rooftop, while the color-coded indicator line keeps you oriented at the service port. Rated 800 PSI working / 4,000 PSI burst, low-loss fittings, standard 1/4" SAE connections.

Common questions
Answers from the warehouse floor.
Still stuck? Call our techs at 305-720-0044.
Does HCPRO warranty the products?
Yes — every HCPRO Black Knight product ships with a 1-year limited warranty against manufacturing defects under normal professional use. We'll replace the manifold, gauges, or hoses if they fail to meet stated specs. See our full warranty terms.
Which Black Knight manifold should I pick?
This is the HC-BK2V2YF5, the Black Knight Mobile A/C manifold for R-1234YF service with included quick-connect adapters. For HVAC HFC (R-410A / R-22 / R-404A / R-134a), commercial refrigeration (R-404A / R-407C / R-507), A2L (R-32 / R-454B), or hydrocarbon (R-290 / R-600), switch families using the tool finder — we sell dedicated manifolds for each refrigerant lineup.
What's R-1234YF and why do I need different adapters?
R-1234YF (HFO-1234yf) is the Mobile A/C refrigerant introduced to replace R-134a for environmental regulation compliance. It's used in most vehicles built from 2015 onward (hybrid, EV, ICE alike). The service ports are different from R-134a ports — different sizes and threads to prevent accidental cross-charging. The included R-1234YF quick-connect coupler adapters mate to the new service ports without separate purchases ($40-60 if bought separately).
What does "Class 1.6" gauge accuracy mean?
Class 1.6 is the European Standard for analog pressure gauge accuracy — readings are within ±1.6% of full scale across the operating range. For a 500 PSI gauge, that's ±8 PSI. This is the professional service tier (Class 2.5 is consumer-grade, Class 1.0 is lab-grade). Class 1.6 gives you the precision needed for proper subcool / superheat charging without the cost of lab-grade gauges.
What refrigerants is this manifold for?
This set ships pre-calibrated for R-1234YF (HFO-1234yf) only — the dominant Mobile A/C refrigerant for vehicles built 2015 forward. The included R-1234YF quick-connect coupler adapters are the difference between bay-ready and bay-blocked on hybrid/EV A/C service. For R-134a Mobile A/C (pre-2015 vehicles), HVAC HFC service, commercial refrigeration, hydrocarbon, or A2L residential A/C, see the dedicated Black Knight manifolds.
Can I use these hoses on a different manifold body?
Yes — the HCPRO Dual Force hoses use standard 1/4″ SAE connections on the manifold side. The R-1234YF service-port end uses the quick-connect coupler adapters included in the kit. For R-134a service on pre-2015 vehicles, you can swap the YF adapters for standard 1/4″ SAE quick-connects (sold separately).
Can I replace just one gauge if it breaks?
Yes — we sell 3-1/8″ replacement gauges separately in °F/PSI and °C/PSI variants, pre-calibrated for R-410A/R-22/R-404A/R-134a or for R-1234YF, R-32, R-290/R-600. See the replacement gauge collection or use the tool finder above to filter by your refrigerant.
Can I return an unused manifold set?
Yes — free returns within 30 days for unused sets in original packaging with all hoses, gauges, and inserts present. Read our full return policy.
Do you offer fleet pricing for shops?
Yes — trade pricing on this page, plus volume discounts for shops outfitting multiple service trucks. Email hcproproductsusa@gmail.com with your fleet size and we'll send a custom quote within 24 hours.
If you have any questions, you are always welcome to contact us. We'll get back to you as soon as possible, within 24 hours on weekdays.
