Bsc Preferred MK110WH Valve Marker Case of 12

Product Description

The BSC PREFERRED MK110WH is a disposable valve marker designed for trade professionals who need fast, reliable pipe and valve identification in the field. The marker lays down permanent, weatherproof, opaque marks that dry quickly on glass, polyethylene, PVC, and other non-porous surfaces. With a long-lasting tip and a high ink volume, the MK110WH is built for repeated, heavy-use marking tasks in HVAC, plumbing, and industrial service environments. Each case contains 12 markers. This product is equivalent to part number H-257W.

The MK110WH valve marker suits residential and commercial service work where clear, durable identification of valves, pipe runs, and equipment components is required. Plumbers, HVAC technicians, and pipefitters use this marker when labeling shutoffs, circuit valves, zone controls, and other components that must remain legible after exposure to moisture, temperature swings, and handling. Its opaque white ink shows clearly on dark pipe, black poly, and other surfaces where standard ink markers fail to provide contrast.

Installation Notes

No tools or shutoffs are required for marker use. Ensure the surface is clean and dry before marking to maximize ink adhesion and legibility. For pipe and valve identification work, follow applicable labeling standards for the trade and jurisdiction. Store markers horizontally to preserve tip saturation when not in use.
