Mastercool 30 lb A2L Recovery Cylinder — Left‑Hand Thread, Dual‑Access Y‑Valve, DOT Certified

This heavy-duty, empty recovery cylinder is purpose-built to handle A2L refrigerants safely while meeting DOT-4BA400 and Transport Canada standards. The tank ships clean and dry, is permanently DOT-stamped for traceability, and uses a reverse (left-hand) threaded 1/4" FL-M fitting with a dual-access Y-valve so technicians can recover liquid and vapor separately. Constructed from powder-coated steel and assembled and tested in the U.S., it’s a reusable solution designed for HVAC professionals who work with mildly flammable refrigerants.

How does the left-hand threaded connection improve safety?

The reverse (left-hand) 1/4" FL-M fitting prevents accidental hookup to standard right-hand threaded equipment, reducing cross-connection risk on job sites. The cylinder’s dual-access Y-valve lets you isolate liquid and vapor lines during recovery for cleaner transfer and easier handling.

• Reverse (LH) 1/4" FL-M connection to deter incorrect connections
• Dual-access Y-valve for separate liquid and vapor recovery
• Optional adapter (90417) available to interface with right-hand threaded hoses
• Ships empty and dry for immediate, controlled use

What safety features protect the cylinder during use?

Safety is baked into the design with a factory-set relief valve and pressure ratings that specify safe operating limits. The built-in relief valve activates at 600 PSI and the tank should be filled to no more than 80% of nominal capacity to leave required vapor space.

• Safety-relief valve set at 600 PSI to prevent overpressure
• Service pressure 400 PSI; tank test pressure 800 PSI for verified strength
• Permanently DOT-stamped with specification and manufacture date for compliance tracking
• Powder-coated steel body and protective collar for jobsite durability

What are the practical specs and handling details technicians need to know?

This compact cylinder balances capacity and portability: a 30 lb nominal size with a 26.2 lb water capacity and a tare weight that keeps it manageable in the field. The collar-style top simplifies lifting and protects the valve assembly during transport and storage.

• Overall size: 9.125" diameter x 17.52" height for easy storage
• Tare weight 17.99 lb; nominal water capacity 26.2 lb (11.9 L)
• Air tightness and service ratings at 400 PSI; tank tested to 800 PSI
• HP295 steel body with yellow/gray powder coat and red safety stripe

How can I use this with standard recovery hoses and accessories?

The cylinder’s left-hand (reverse) thread is specifically for A2L service. If your existing hoses are right-hand threaded, Mastercool offers a 90417 conversion adapter to bridge the connection safely. Always confirm compatibility before changing fittings or charging cylinders.

• Ships with left-hand 1/4" FL-M fitting for direct A2L service
• 90417 adapter (sold separately) converts to right-hand threaded hoses
• Reusable design supports repeated recovery cycles when used per guidelines
• Recommended fill limit: no more than 80% of capacity for safe vapor space

HVAC technicians, refrigeration service shops, fleet maintenance teams, and contractors who work with A2L-class mildly flammable refrigerants and need a DOT- and TC-approved, reusable recovery cylinder. Choose this Mastercool 62010-A2L when you require a compact, traceable, and safety-focused empty cylinder that’s ready to integrate into professional recovery workflows.
