Rectorseal ns-uni-50pk Universal Cap Silver 50 Pack

Product Description

The RECTORSEAL ns-uni-50pk is a pack of 50 universal refrigerant service port caps designed to secure service valves and refrigerant tanks against tampering, theft, and vandalism. Each cap measures 0.25 inches and features a built-in O-ring seal that provides a positive backup seal for leaking service valves. The corrosion-resistant silver finish is color-coded to help identify refrigerant type and prevent accidental mixing.

They are commonly installed on systems during seasonal shutdowns, post-service closeouts, or any situation where unattended equipment is at risk of unauthorized access.
