Flame King 50LB A2L Refrigerant Recovery Cylinder, 400 PSI with Dual Y-Valve and Heavy-Duty Steel

Flame King 50LB A2L refrigerant recovery cylinder is a heavy-duty, DOT/TC-certified steel tank engineered to safely recover, store and transport mildly flammable A2L refrigerants up to 400 PSI.

This recovery cylinder is built for HVAC professionals and service shops that handle next-generation low‑GWP refrigerants. Manufactured in ISO 9001 facilities and tested to DOT-4BA-400 standards, the tank combines safety features—reverse (left‑hand) threads, a pressure relief valve and dual liquid/vapor Y-valve—with durable welded steel construction and a corrosion‑resistant powder coat finish. It arrives pre-purged, X‑ray and hydrostatically tested, and is vacuum-ready so technicians can integrate it into their existing recovery workflows immediately.

How is this tank certified for professional refrigerant recovery?

The Flame King 50LB cylinder meets DOT-4BA-400 specifications and is certified by Transport Canada, manufactured in ISO 9001 facilities and aligned with AHRI guidance. It receives X‑ray and hydrostatic testing and is pre-purged so it meets industry safety and quality expectations.

• DOT (Department of Transportation) and TC (Transport Canada) certified
• Manufactured in ISO 9001 certified facilities
• X‑ray and hydrostatic testing performed pre-delivery
• AHRI guideline compatibility for HVAC service use

What safety features protect mildly flammable A2L refrigerants?

Designed specifically for A2L usage, the cylinder includes a built‑in pressure relief valve and reverse (left‑hand) threads to prevent accidental connection mistakes with non‑A2L fittings. The tank’s materials and valves reduce leak risk during recovery, storage and transport.

• Reverse left‑hand threads for A2L-specific fittings
• Integrated pressure relief valve for overpressure protection
• Dual Y-valve provides separate liquid and vapor ports
• Powder-coated steel resists corrosion and abrasion in field environments

How does the dual Y-valve liquid/vapor design help technicians in the field?

The dual Y‑valve lets technicians choose liquid or vapor recovery paths without changing fittings, improving speed and control during service. It streamlines typical recovery sequences and reduces downtime while maintaining safe handling of mildly flammable refrigerants.

• One connection for liquid recovery, one for vapor recovery
• Faster changeover between recovery modes on-site
• Minimizes handling and reduces potential leak points
• Compatible with standard HVAC recovery equipment configured for A2L

What are the construction and readiness features for everyday use?

The tank is made from high‑grade welded steel with a protective powder coat to tolerate shop and field conditions. It ships pre-purged and vacuum-ready so you can begin filling and recovering refrigerant without additional prep work.

• Heavy-duty, refillable welded steel body
• Corrosion-resistant powder coat finish for longevity
• Shipped pre-purged and vacuum-ready for immediate use
• Available in compatible 30LB option (YSN301R-A2L) for smaller jobs

Who is this for: HVAC contractors, refrigeration service technicians, and facility maintenance teams upgrading to low‑GWP, mildly flammable A2L refrigerants. If you need a robust, compliant recovery cylinder that fits current codes and streamlines recovery work while reducing changeover time between liquid and vapor modes, this Flame King 50LB A2L recovery tank is built for professional use. It should be integrated into certified servicing procedures and used with compatible A2L-rated hoses, gauges and recovery equipment.
