HYDROTEST and 6-YEAR MAINTENANCE LABELS are a necessary reminder to keep your customer’s equipment maintenance and inspections up to date. And the benefit is, we’ll custom imprint these labels with your company name, address, and phone number so your customer knows who to call. Plus you choose the material—white or blue vinyl or silver metallic that shows “Void” when removed—as recommended in NFPA 10. Minimum order is 1000 for vinyl and 500 for metallic labels. Sold and priced per 100. Delivery is four to six weeks.
