The BSC PREFERRED MK110GN is a disposable valve marker designed for permanent, weatherproof marking on non-porous surfaces including glass, polyethylene pipe, and other smooth materials commonly encountered in plumbing, HVAC, and industrial service work. The fast-drying, opaque ink resists fading and moisture after application, making it reliable for labeling valves, equipment, and piping systems in the field. Each case contains 12 markers. The long-lasting tip maintains a consistent mark across repeated use, reducing waste on the job site.
The MK110GN valve marker is suited for trade professionals who need clear, durable identification markings on piping, valve handles, conduit, and mechanical equipment. Its opaque ink performs on dark and light surfaces alike, making it practical for both indoor mechanical rooms and outdoor installations where standard markers fail. The case quantity of 12 supports crew-level supply stocking for service departments, contractors, and supply rooms.
Designed for use on non-porous surfaces including glass, polyethylene, and similar materials. Suitable for valve and equipment labeling in plumbing, HVAC, and mechanical service applications.
No installation is required for this consumable marking tool. Store markers with the cap secured to prevent tip drying. Allow marks to dry fully before handling marked surfaces in wet or high-humidity environments. Dispose of used markers in accordance with local waste regulations.
