Rectorseal np-r410-10pk R-410A Locking Cap 10 Pack

Product Description

The RECTORSEAL np-r410-10pk is a refrigerant locking cap designed to secure service ports on R-410A systems against unauthorized access and accidental refrigerant loss. Constructed from high-grade brass and aluminum, this cap threads onto 1/4-inch service port fittings and features a distinctive pink color coded specifically for R-410A refrigerant identification. Sold in a 10-pack, it suits service techs who maintain multiple residential or light commercial systems and need a reliable, code-conscious way to cap off ports after servicing.

This locking cap is intended for use on R-410A refrigerant systems, including split-system air conditioners and heat pumps equipped with standard 1/4-inch threaded Schrader-type service ports. The pink color coding aligns with industry refrigerant identification standards, making it easy to confirm the correct cap is in place at a glance. The 10-pack format supports fleet-level service operations where multiple units are serviced per visit.

Installation Notes

Licensed HVAC technicians install refrigerant locking caps as part of routine system service and EPA Section 608 compliance practices. Power down the system and recover or isolate refrigerant pressure before working on service ports. Thread the cap by hand until snug, then use an appropriate cap key or tool to engage the locking mechanism. Do not overtighten, as brass and aluminum fittings can be damaged by excessive torque.
