Bsc Preferred MK101RD Valve Marker Case of 12

Product Description

The BSC PREFERRED MK101RD is a disposable valve marker designed for bold, fast-drying, waterproof marking in trade and industrial settings. It lays down high-visibility marks on corrugated board, wood, and other porous surfaces, making it a go-to tool for techs who need to label valves, pipes, equipment, and components quickly in the field. The long-lasting tip holds up through repeated use, and the ink formula is engineered to dry fast and resist moisture once applied. Sold as a case of 12 markers, this SKU is suited for shops and service fleets that want to keep marking supplies on hand without frequent reorders.

The MK101RD is appropriate for HVAC technicians, plumbers, pipefitters, and general maintenance personnel who mark valve positions, flow directions, and service notes directly on equipment or packaging. It performs on corrugated cardboard, raw and finished wood, and similar porous materials. Its waterproof finish means marks hold up in damp mechanical rooms, outdoor installations, and wet service environments. This marker is equivalent to part number H-256R, making it a recognized direct replacement for that reference in supply house and shop inventories.
