Bsc Preferred MK110YE Yellow Valve Marker Case of 12

Product Description

The BSC PREFERRED MK110YE is a disposable valve marker designed for use in plumbing, HVAC, and industrial piping applications where durable, readable labeling is required. It produces permanent, weatherproof, fast-drying, opaque marks that adhere to glass, polyethylene, and other non-porous surfaces. The marker is sold as a case of 12 units, making it a practical stock item for service vans and facility maintenance programs. Techs and plumbers rely on this type of marker for valve identification, system tagging, and field documentation where markings must hold up to moisture and temperature variation.

The MK110YE is suited for residential and commercial trade applications wherever pipe, valve, or equipment labeling is needed. Common install scenarios include marking shutoff valves, identifying zone controls, tagging refrigerant lines, and annotating system components during commissioning or service. The yellow ink provides high contrast on metal, plastic, and glass surfaces commonly found in mechanical rooms and utility spaces. This marker is equivalent to part number H-257Y.

Installation Notes

No special tools or trade license are required to use valve markers, but they are typically applied by licensed plumbers, HVAC technicians, and pipefitters as part of system commissioning or service documentation. Allow marks to dry fully before exposing to water or direct contact. Follow local codes and job specifications for valve identification labeling requirements. Store markers at room temperature and away from direct sunlight to preserve ink performance.
