VISIBLE INDICATION OF LEAKS
MILSHEFF SPRAY-STOPS SAFETY COVERS provide a much needed early-warning, visible indication of leakage. A color change triggered only from the inside by a leak enables even untrained employees to see that a leak has occurred. Even a single drop of acid will bleach the inside coating; an outside spray will not affect the color. Visible from a distance, the color change hastens discovery and reduces damage. Everyone, in effect, becomes an inspector.
If leakage does occur—whether drops, spray or stream—MILSHEFF Covers deflect it from spraying adjacent areas and personnel.
All models of valve and flange covers are fully-indicating (meaning the actual material changes color) except Teflon flange covers which indicate through a patch, and Teflon valve covers.
