This is a 30 lb steel cylinder of R-134A refrigerant, factory sealed, for automotive, commercial, and residential cooling systems that call for R-134A.
Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
R-134A has been a standard refrigerant choice across automotive and commercial cooling for years, largely because it is stable, well-documented, and non-flammable under the ASHRAE classification system. This page lists a 30 lb factory-sealed cylinder from OnTap Cold. As with any refrigerant, purchase and handling come with legal requirements — details below.
What's in the Box
- One (1) 30 lb steel cylinder of R-134A refrigerant, factory sealed
- Tank included (refrigerant ships in its own cylinder, not a separate refillable tank)
Not included: hoses, gauges, manifold sets, recovery equipment, or any dispensing hardware. This listing is refrigerant and cylinder only.
Professional Requirements & Limitations
Federal law under EPA Section 608 requires technician certification to purchase and handle regulated refrigerants, including R-134A in cylinders of this size. Sellers are required to verify certification before releasing product. If you do not hold EPA 608 certification, you cannot legally take possession of this cylinder for servicing equipment.
R-134A is classified ASHRAE A1 — non-flammable, non-toxic, non-corrosive. It is not an A2L (mildly flammable) refrigerant, so none of the spark-proof or A2L-specific handling precautions that apply to R-32 or R-454B apply here. Standard refrigerant handling practices still apply: keep the cylinder in a cool, dry, ventilated space, out of direct sunlight, and away from oxidizing agents.
Pro-Installer Tip
Pulling a vacuum on an R-134A system before charging is where a lot of comebacks start or get prevented. Moisture and non-condensables left in the lines mix with refrigerant and oil to form acids, which attack compressor windings over time and shorten equipment life. Use a micron gauge — not just the compound gauge on your manifold — to confirm the system has reached and held a deep vacuum, ideally below 500 microns, before you introduce R-134A. Pair this with a valve core removal tool so you're pulling vacuum through full-port access instead of restrictive Schrader valves. This isn't optional best practice; EPA Section 608 requires evacuation to specified vacuum levels before recharging, and skipping it is both a compliance issue and a callback waiting to happen.
Key Benefits
- 30 lb fill gives you enough refrigerant for multiple service calls without switching cylinders mid-job
- Non-flammable, non-toxic, non-corrosive — no A2L handling protocol required
- Zero ozone depletion potential due to chlorine-free composition
- Factory sealed cylinder for verified, uncontaminated charge

Compatibility & Fitment
Compatible with automotive air conditioning systems, commercial refrigeration, household cooling systems, industrial cooling units, central air conditioning, and dehumidification systems designed for R-134A. Also used in non-cooling industrial applications such as medical aerosol production, plastic foam manufacturing, and insecticide carriers, per manufacturer data.
Not compatible with systems designed for R-410A, R-32, or R-454B — this is R-134A only, and refrigerants should never be mixed or substituted across systems designed for a different gas. Hoses, gauges, and recovery/charging equipment are NOT included and must be sourced separately. This listing does not include a manifold set or vacuum pump.
FAQ
Is EPA certification required to buy this?
Yes. EPA Section 608 certification is required by federal law to purchase and handle this refrigerant.
Is this tool rated for A2L refrigerants like R-32 and R-454B?
This product is R-134A, an ASHRAE A1 (non-flammable) refrigerant — it is not an A2L product and A2L compatibility does not apply to it.
What is included with the cylinder?
One 30 lb factory-sealed steel cylinder of R-134A. Hoses, gauges, and dispensing equipment are not included.
Can I use this in a system designed for R-410A or R-32?
No. R-134A is not interchangeable with R-410A, R-32, or R-454B. Use only in systems designed for R-134A.
Compliance & Warranty
This cylinder ships new and factory sealed. EPA Section 608 certification is required for purchase — this is a federal requirement, not a store policy. Review manufacturer warranty terms under the "Resources (System Manuals and Warranty)" Tab above before ordering. If you have questions about certification requirements or storage before you buy, ask us — we always reply back.
