Jb Industries shld-a2l-sl20 A2L Locking Cap Sleeves Red 20-pack

Product Description

The JB INDUSTRIES shld-a2l-sl20 is a pack of 20 red locking cap sleeves designed to fit over JB Shield brass refrigerant locking caps. These sleeves add a secondary layer of sealing protection at the service port, helping to reduce refrigerant loss and contamination risk. The red color coding matches the appearance of A2L refrigerant recovery tanks, allowing technicians to quickly identify systems charged with A2L refrigerants such as R32 and R454B. Made from brass and rated to resist UV exposure and moisture, these sleeves hold up in outdoor and rooftop installations where corrosion is a real concern.

These sleeves are intended for HVAC and refrigeration systems using A2L refrigerants. The color-coded design supports quick visual identification during service calls, which is especially useful when multiple systems are present on a job site. They are suited for residential and light commercial applications where A2L refrigerant use is increasing due to updated equipment efficiency standards. Licensed HVAC technicians installing or servicing split systems, mini-splits, and packaged units with A2L refrigerant will find these sleeves a practical addition to their standard cap protocol.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable refrigerant handling regulations and EPA Section 608 requirements.
