The MA-LINE MA-SR438A is a pack of 10 blue refrigerant identification tags designed for use with R-438A refrigerant systems. These tags provide a clear, color-coded visual reference that identifies the refrigerant type in a system, supporting safe service practices and reducing the risk of cross-contamination during maintenance or recharge. HVAC technicians apply these tags to service ports, line sets, or equipment panels to communicate refrigerant type to anyone working on the system. The blue color designation aligns with industry conventions for R-438A identification.
These refrigerant tags are used in residential and light commercial HVAC applications where R-438A is the system refrigerant. They are appropriate for any installation or service scenario where refrigerant labeling is required, including new equipment installations, refrigerant retrofits, and routine service calls. Each pack contains 10 tags, making it practical to stock for multiple jobs or a full service van supply.
Designed for use on HVAC systems charged with R-438A refrigerant. Suitable for any residential or light commercial equipment where R-438A identification labeling is required.
Refrigerant tags are applied by licensed HVAC technicians as part of standard service documentation and labeling procedures. Attach tags securely to service ports, line sets, or visible equipment locations where the label will remain legible over time. Always recover and properly handle refrigerant before performing any service work on the system in accordance with EPA Section 608 regulations. Do not apply tags to surfaces where adhesion or visibility may be compromised by heat, oil, or moisture exposure.
