Sealing Fluid

Mailing Machine Sealing Solution — Every Size for Every Mailroom

Professional-grade envelope sealing solution compatible with every mailing machine on the market — Pitney Bowes, Quadient, Formax, FP Mailing, Hasler, Francotyp Postalia, and all others. Available in multiple sizes and formats from 1 gallon to 55 gallons — pre-mixed liquid, concentrated liquid, or our revolutionary powder concentrate that ships lightweight and saves you 50–85% over OEM pricing.

💡 Did you know? Pre-mixed sealing solution is 95% water — and you're paying to ship every pound of it. Our powder concentrate ships in a zip-lock bag. You add water locally and save up to 85% on every order. Read the Complete Sealing Solution Guide →

Powder Concentrate — Our Best Value Line

Same professional-grade active ingredients as Pitney Bowes E-Z Seal and Quadient Sure Seal. Ships in a lightweight zip-lock packet. Just add water.
