Rectorseal 86693 Locking Refrigerant Cap Universal Silver EACH

Product Description

The RECTORSEAL 86693 is a universal locking refrigerant cap designed to seal standard Schrader service valves on central air conditioning units and mini-split systems. Each cap features a 1/4-inch thread and is engineered to help prevent refrigerant leakage, protecting technicians and building occupants from exposure to dangerous gases. Installation and removal require a special proprietary tool, reducing the risk of unauthorized access or accidental valve actuation. Caps are color-coded silver and embossed for fast visual identification in the field.

These caps are suited for HVAC technicians servicing residential and light commercial refrigerant systems, including split-system central air conditioners and ductless mini-splits. The universal fitment covers standard Schrader valve service ports commonly found across a wide range of equipment. Proper use at every service port helps prevent accidental refrigerant mixing between systems and limits liability exposure during and after service calls.

Installation Notes

Installation and removal must be performed by a licensed HVAC technician using the required proprietary tool.
