ACM-003 Tamper evident wrap and lock dust seal cover for post valves 500 Pack

Tamper evident wrap and lock dust seal cover for medical cylinders with a post valve. This seal cannot be taken off without breaking it making it truly tamper evident.  The front of the cap has a place to store a sealing washer.  This seal simply wraps around the valve and locks together.  The post goes inside the valve orifice and keeps the seal from sliding off when you pick up the cylinder by the valve.
