A2L transition ready.
°F + °C dual scale.
Forged brass body.
The HCPRO Black Knight A2L manifold is the professional-grade tool for the A2L refrigerant transition — forged brass body, Class 1.6 calibrated °F + °C dual-scale gauges pre-calibrated for R-32 / R-410A / R-454B, and Dual Force premium black hoses. Engineered for HVAC contractors navigating the A2L transition window — servicing new R-454B residential installs alongside the existing R-410A install base.
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 °F + °C dual-scale gauges
Large 3-1/8″ (80mm) analog gauges with Class 1.6 accuracy and both °F and °C dual-scale readings, pre-calibrated for R-32, R-410A, and R-454B. The dual-scale face is a real differentiator on hydrocarbon manifolds — international metric A2L commissioning documentation reads alongside US shop charging specs without conversion tables. 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.

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?
Use the tool finder above — within the A2L family, the HC-2V2Y5LP 3 ft is the compact option for residential mini-split installs, the HC-2V2Y3LP 5 ft is the full-length pro option. For HVAC HFC (R-410A pure / R-22 / R-404A / R-134a), commercial refrigeration, hydrocarbon, or R-1234YF mobile A/C, switch families using the filter — we sell dedicated manifolds for each refrigerant lineup.
What's the A2L refrigerant transition?
The HVAC industry is moving from high-GWP HFC refrigerants (R-410A) to lower-GWP A2L refrigerants (R-32 in mini-splits since ~2018, R-454B in new residential systems since 2025). A2L = mildly flammable (lower ignition risk than A3 hydrocarbons but higher than non-flammable HFCs). The transition period means you'll service both R-454B new installs AND R-410A legacy systems for the next 15+ years. This manifold covers both, plus R-32 — one tool for the whole transition window.
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-32, R-410A, and R-454B — the A2L transition refrigerant set. R-454B is the new A2L residential A/C standard (Carrier, Trane, Lennox systems built from 2025 forward). R-410A is the dominant legacy refrigerant in the existing residential install base. R-32 is the standard A2L mini-split refrigerant globally. For commercial refrigeration (R-134a / R-404A / R-407C / R-507), hydrocarbon (R-290 / R-600), or R-1234YF mobile 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 and fit any HVAC manifold with the same fitting standard (which is most professional manifolds on the market). You can buy replacement Black Knight hoses separately if you want to upgrade an older manifold body without replacing the gauges.
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.
