Seal Supply

What Seal Supply does

Seal Supply B.V. is a privately held Dutch technical-sealing distributor headquartered in Hattemerbroek, Netherlands. The company sells a broad portfolio of static, rotary, hydraulic, and pneumatic seals — including O-rings, X-rings, oil seals, piston and rod seals, scrapers, guide bands, and end caps — alongside sliding bearings, tools, repair kits, and lock springs. Its catalogue of more than 60,000 articles is held in stock and served through a 24/7 account-based webshop accessible in Dutch, German, and English, supported by a Kardex Remstar shuttle system in a dedicated warehouse.

Beyond catalog distribution, Seal Supply runs in-house custom manufacturing using PU1TEC CNC machines with more than 25 elastomer and polymer materials available, allowing rapid production of seals for critical industrial environments. The company is the official distributor of Hallite for the Dutch market and carries A-brand lines from HUNGER and Garlock, while also marketing its own proprietary Evolast FFKM O-ring compound positioned as an alternative to Kalrez for high-temperature and chemically aggressive applications.

Commercially, Seal Supply operates a one-time product-sale revenue model with quote-based, account-specific pricing and no public rate cards. Its go-to-market combines a self-serve 24/7 webshop with inside sales via phone and email, targeting three verticals — industrial manufacturing, MRO (maintenance, repair, operations), and technical wholesale — primarily in Western Europe. The business is independently owned with no disclosed funding rounds, parent company, or institutional investors.
