Mastercool 30 lb A2L Recovery Cylinder — Left‑Hand 1/4" FL‑M, DOT‑Compliant, Powder‑Coated

This specialized cylinder is engineered for HVAC technicians and service shops that handle low‑GWP, mildly flammable refrigerants. It ships empty (refrigerant not included) and is purpose‑built with a reverse (left‑hand) 1/4" FL‑M connection to prevent accidental cross‑connection to non‑A2L systems. Constructed from heavy‑gauge, powder‑coated steel with an integrated safety collar and relief valve, the unit meets DOT‑4BA400 and Transport Canada standards and arrives clean and ready for immediate use.

How does the left‑hand threaded connection improve on‑job safety?

The cylinder uses a reverse (left‑hand) 1/4" FL‑M fitting so A2L hoses and equipment can be clearly distinguished from conventional refrigerant fittings, lowering the chance of cross‑connection. This mechanical incompatibility reduces human error and supports a safer service workflow.

• 1/4" FL‑M (left‑hand) thread prevents standard right‑hand hose hookup
• Dual‑access Y‑valve separates liquid and vapor recovery for controlled transfer
• Optional 90417 adapter lets you connect right‑hand hoses when required (sold separately)

What safety features protect the cylinder and technician?

Safety is built into the design with a factory‑set relief valve rated at 600 PSI and strict fill limits to maintain safe working pressures. The cylinder is permanently DOT‑stamped so you can verify specification and manufacture date at a glance.

• Safety‑relief valve set to 600 PSI; do not fill past 80% capacity
• Tank test pressure 800 PSI and service pressure 400 PSI for robust performance
• Permanent DOT stamping for traceable compliance and authenticity

How durable and transport‑ready is the Mastercool 62010‑A2L?

Built from heavy‑gauge HP295 steel with a powder‑coated yellow/gray finish and red safety stripe, the cylinder resists corrosion and normal jobsite wear. The collar and overall sizing make handling, storage, and transport straightforward for technicians on the road.

• Powder‑coated steel body resists chips and corrosion in shop environments
• Collar design improves handling and protects valves during transport
• Compact footprint (9.125" x 17.52") fits standard storage and service racks

Will this cylinder meet regulatory and field requirements?

Yes — the Mastercool 62010‑A2L conforms to DOT‑4BA400 specification, ARI guidelines, and is TC approved. It is assembled and tested in the U.S., shipped with a clean, dry interior, and intended for reuse in accordance with applicable regulations.

• DOT‑4BA400 and Transport Canada approved for verified compliance
• 100% U.S. assembled and tested for consistent quality control
• Reusable design meets industry recovery and transport expectations

Who is this for?

The Mastercool 62010‑A2L is aimed at HVACR professionals, service contractors, and fleet technicians who are transitioning to A2L refrigerants or maintaining mixed fleets. If you require a rugged, regulation‑compliant empty recovery cylinder with left‑hand A2L connections, DOT verification, and field durability, this model gives technicians the mechanical safety features and traceability needed for everyday shop and service work. Note: refrigerant is not included; use approved hoses, adapters (90417 optional), and follow all applicable local regulations and safety procedures when recovering or transporting A2L refrigerants.
