Jb Industries shld-a2l50 A2L Locking Caps 1/4 in 50 Pack

Product Description

The JB INDUSTRIES shld-a2l50 is a 50-pack of 1/4-inch locking service port caps engineered specifically for A2L refrigerant systems. These caps are part of the SHIELD line and are designed to secure Schrader-style service ports on equipment charged with mildly flammable A2L refrigerants such as R-32, R-454B, and R-410A replacements. The locking design helps prevent unauthorized access, accidental venting, and contamination of the refrigerant circuit. HVAC technicians use these caps to maintain system integrity and meet evolving code requirements tied to A2L refrigerant handling.

These locking caps are suited for residential and light commercial HVAC systems using A2L refrigerants. They fit 1/4-inch service ports commonly found on mini-split systems, heat pumps, and refrigerant manifold hose connections. The 50-pack quantity supports service fleets and contractors who need to cap multiple units on a single job or stock caps across a service van inventory.
