What We Do

We make refrigerant selection easier to understand.

Refrigerant purchases are often technical by nature. The correct product depends on the equipment, service application and manufacturer requirements. Our goal is to present the information customers need in a cleaner and more direct format.

Jay Industry focuses on refrigerant products such as R22, R32, R134A, R404A, R407C, R410A and R454B, with product pages that emphasize the refrigerant designation, cylinder size and compatibility considerations.

We believe a specialty supply store should help customers compare products without unnecessary clutter. That means straightforward product presentation, clear pricing and direct access to current inventory.

Our Priorities

What we want every Jay Industry customer to get.

The store is designed around a few simple ideas that matter when buying refrigerant online.

Useful Information

Product content should help customers understand what they are looking at before they place an order.

Compatibility Awareness

Refrigerants are not interchangeable. We encourage customers to verify equipment requirements before purchasing.

Simple Ordering

Customers should be able to move from product comparison to checkout without an unnecessarily complicated buying process.

How We Think

Specialized products deserve a specialized storefront.

Rather than treating refrigerants like generic merchandise, Jay Industry organizes the shopping experience around the details that matter for technical products.

Identify the refrigerant clearly

Customers should know the refrigerant designation immediately when viewing a product.

Show practical product details

Cylinder size and product information should be visible without unnecessary searching.

Keep safety and compliance visible

Refrigerant handling, purchasing and servicing requirements may apply depending on the product and use.

Professional Responsibility

Correct refrigerant selection starts with the equipment.

Buyers should confirm the refrigerant specified on the equipment nameplate or in manufacturer service documentation. Applicable federal, state and local rules may govern refrigerant purchasing, servicing, recovery, transport, storage and disposal.

TECHNICAL REFRIGERANT GUIDANCE

Technical refrigerant questions, explained more clearly.

Use this guide as a practical reference before ordering refrigerant. It covers equipment identification, cylinder sizing, charging basics, service tools, A2L considerations and common compatibility questions.

Compatibility Charging Basics Cylinder Sizes A2L Refrigerants Service Equipment

01 How do I confirm which refrigerant my system is designed to use?

Start with the equipment data plate, then compare that information with the manufacturer’s installation or service documentation. The required refrigerant should be identified by designation, such as R410A, R32, R454B, R404A, R407C, R22 or R134A.

Before ordering: Match the product to the refrigerant specified for the equipment. Similar-looking systems can require completely different refrigerants.

02 Can R32 or R454B be used as a direct replacement for R410A?

No. R410A, R32 and R454B have different operating characteristics, safety classifications and equipment requirements.

R32 and R454B are A2L refrigerants. Systems designed for A2L use may include safety features and service requirements that equipment built for R410A does not have.

Use only a refrigerant or retrofit method specifically approved by the equipment manufacturer.

03 What is the main difference between R410A, R32 and R454B?

All three can appear in air-conditioning and heat-pump applications, but they are separate refrigerants and should not be treated as interchangeable.

R410A: common in many existing residential and commercial HVAC systems.
R32: used in newer equipment specifically designed and labeled for R32.
R454B: used in newer HVAC equipment engineered and approved for R454B.

Always follow the refrigerant designation shown on the equipment and in the manufacturer’s documentation.

04 Is it okay to mix two different refrigerants together?

Different refrigerants should not be mixed unless a specific, manufacturer-approved service procedure explicitly requires it.

Mixing can change pressure-temperature behavior, reduce system performance and make proper recovery or future servicing more difficult.

Do not substitute another refrigerant only because the specified refrigerant is temporarily unavailable.

05 What does a 20 lb, 25 lb or 30 lb refrigerant cylinder rating mean?

The listed weight generally refers to the stated net refrigerant contents, not the full shipping weight of the filled cylinder.

The cylinder shell, valve, protective packaging and shipping materials add weight beyond the refrigerant itself.

Use the actual cylinder label as the final reference for net contents.

06 Does one refrigerant cylinder equal one complete system charge?

Not necessarily. Refrigerant charge requirements vary with system capacity, equipment design, line-set length and installation details.

Factory charge information is typically listed on the equipment data plate or in the installation documentation.

Ordering tip: Determine the required charge before buying instead of assuming one cylinder corresponds to a fixed number of systems.

07 Should refrigerant charging be based on pressure or refrigerant weight?

The correct charging method depends on the equipment and the manufacturer’s approved service procedure.

Refrigerant weight is often important, while pressure, temperature, subcooling and superheat measurements may also be required depending on system design and operating conditions.

Follow the manufacturer’s service data rather than relying on one universal charging rule.

08 Why do different refrigerants operate at different pressures?

Every refrigerant has its own pressure-temperature relationship. Expected system pressure changes with refrigerant type, temperature and operating conditions.

A pressure reading that is normal for one refrigerant should not be used as the reference for another.

Gauges, hoses, fittings and other service tools should be rated for the refrigerant and pressure range being serviced.

09 What tools are commonly used for professional refrigerant service?

The exact tool list depends on the job, but common professional service equipment can include:

Refrigerant-compatible manifold gauges
Properly rated hoses and fittings
Refrigerant charging scale
Vacuum pump
Micron gauge
Leak-detection equipment
Recovery machine and recovery cylinder
Temperature measurement tools

A2L refrigerants may require equipment and procedures specifically suitable for mildly flammable refrigerant service.

10 What should be checked before adding refrigerant to a low system?

A low charge can be a sign of a leak or another system problem. Adding refrigerant without finding the cause may leave the original issue unresolved.

A qualified technician should evaluate the system, correct leaks where required, confirm system integrity and recharge it according to the manufacturer’s service procedure.

11 How should refrigerant cylinders be stored?

Follow the storage instructions printed on the cylinder and any manufacturer guidance supplied with the refrigerant.

Cylinders should generally be secured in an appropriate, well-ventilated location and protected from excessive heat, physical damage and unauthorized handling.

A2L refrigerants require additional attention to applicable storage and handling requirements.

12 Can R22 still be used to service older equipment?

Existing equipment originally designed for R22 may still require R22 or a properly approved retrofit solution during service.

Refrigerant selection should be based on the equipment, manufacturer guidance, approved procedures and current regulatory requirements.

Do not use an alternative refrigerant only because its operating characteristics appear similar.

13 What does the A2L classification mean for R32 and R454B?

A2L is a refrigerant safety classification associated with lower flammability characteristics than more highly flammable classes.

Equipment designed for A2L refrigerants incorporates related safety requirements. Service personnel should use appropriate tools, procedures and equipment when working with these systems.

Never charge an A2L refrigerant into equipment that was not designed and approved for that refrigerant.

14 Can certification or purchaser documentation be required to buy refrigerant?

Refrigerants used in stationary air-conditioning and refrigeration systems can be subject to U.S. EPA refrigerant sales requirements.

Section 608 technician certification or other qualifying purchaser documentation may be required depending on the transaction and intended use.

Buyers are responsible for meeting applicable federal, state and local requirements for purchasing, handling, recovery and service work.
