Our Story

Seals-it was started in 1993 when Stan Maczak saw the opportunity to custom engineer rubber seals and gaskets bonded to metal for an aerospace customer. By utilizing the tooling expertise of sister company, Allyn Tool, Seals-It was able to engineer, design, test and manufacture parts entirely in-house. While other companies were cutting costs (and increasing lead times) by sending manufacturing overseas, we found our niche in Ellington, CT. 

Our mission is to always serve the industry, and go the extra mile through vigorous testing and modeling. That sets us apart and our clients think so too.

Solution Parts With Rapid Prototyping

3D Prototyping is the catalyst for momentumand a solution for an ever-changingenvironment. Using the latest technology and software we provide rapid prototypingrubber-to-metal seals, gaskets, plugs and otherparts customers have relied on for decades.Because these pieces don’t require specializedmolds used in traditional methods, this meansin-hand delivery in days, not weeks. Prototypescan be adjusted and reengineered, reprinted easily until perfected, cutting down on part development costs, lead times and fiscal risks. Customers using Seals-it for final production are credited production costs associated in 3D printed prototypes.
