Why Black Knight

Commercial refrigeration.

Low + med temp.

Forged brass body.

The HCPRO Black Knight refrigeration manifold is the professional-grade tool for commercial refrigeration service — forged brass body, Class 1.6 calibrated dual-scale gauges pre-calibrated for R-134a / R-404A / R-407C / R-507, and Dual Force premium black hoses. Engineered for refrigeration techs running restaurant, grocery, walk-in cooler / freezer, and food-service PM contracts.

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 commercial-refrig dual-scale gauges

Large 3-1/8″ (80mm) analog gauges with Class 1.6 accuracy and dual-scale °C/PSI readings, pre-calibrated for R-134a, R-404A, R-407C, and R-507 — covers low-temp (R-404A / R-507) and medium-temp (R-134a / R-407C) commercial refrigeration in one tool. Shock-proof rubber covers protect against drops in food-service service environments.

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?

Use the tool finder above — filter by hose tier (Premium Standard / Anti-Blowback / Ball Valve) to find the right Commercial Refrigeration configuration. For HVAC HFC systems (R-410A / R-22), A2L systems (R-32 / R-454B), or R-1234YF mobile A/C, switch families using the filter — we sell dedicated manifolds for each refrigerant lineup.

Why a dedicated refrigeration manifold instead of an HVAC manifold?

HVAC manifolds are typically calibrated for high-pressure HFC and A2L systems (R-410A / R-32 / R-454B at 250+ PSI working). Commercial refrigeration runs at lower pressures with different refrigerants — R-134a, R-404A, R-407C, and R-507 — and the gauge faces are pre-calibrated to read those scales directly without conversion. Plus, dedicated refrigeration equipment keeps you organized on PM contracts where you're servicing 10-20 different refrigeration units a week without cross-checking refrigerant scales.

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-134a, R-404A, R-407C, and R-507 — the commercial refrigeration refrigerant lineup. R-134a / R-407C for medium-temp (display cases, beverage coolers, milk coolers); R-404A / R-507 for low-temp (walk-in freezers, ice machines, frozen food cases). For HVAC HFC (R-410A / R-22), hydrocarbon (R-32 / R-290 / R-600), A2L (R-454B), or R-1234YF mobile A/C, see the dedicated Black Knight manifolds for each lineup.

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. 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.
