Bsc Preferred MK110RD Valve Marker Case of 12

Product Description

The BSC PREFERRED MK110RD is a disposable valve marker designed for use by plumbing, HVAC, and facilities maintenance technicians who need a fast, reliable way to label valves, pipes, and equipment in the field. The marker lays down permanent, weatherproof, fast-drying, opaque marks on non-porous surfaces including glass and poly materials. Its long-lasting tip holds up through repeated use on rough or smooth surfaces. Sold as a case of 12, the MK110RD is stocked in volume to support crew kits, truck stock, and maintenance departments. This is a purpose-built field marker, not a general-purpose office supply.

The MK110RD is suited for identifying isolation valves, gate valves, ball valves, and shutoffs in mechanical rooms, utility spaces, and on poly or CPVC piping runs. Plumbers, pipefitters, and HVAC techs use valve markers like this to tag systems during installation, commissioning, and service calls. The opaque ink formula ensures legibility on dark-colored pipe and fittings. The marker functions across a wide range of indoor and outdoor conditions, making it reliable for both new construction and retrofit work.
