Seel-Tite Containment Systems

The Leadership

Four engineers. Fifty-two years. One port standard.

Walter Thorne

Founder & Chief Containment Officer

Walter Thorne

Walt started the company in 1973 because he had a bad week. He made one gasket. It worked. He made another. That one worked too. Fifty-two years later he still signs every port-spec revision, and he still thinks the right answer to most gambles is "don't force it."

Marcus Hadley

Head of Seal Engineering

Marcus Hadley

Marcus owns the seal. Every durometer change, every revision of the silicone recipe, every micrometer of tolerance on the OPX-14 port — he signed it. Quiet in meetings. Loud when the spec is wrong. If the gasket holds, Marcus is why.

Jim Boecker

VP of Disposal Systems

Jim Boecker

Jim runs the ten accessories. He bought a vintage Presto Salad Shooter in 1987 because he liked the mechanism; thirty-eight years later the Salad Shooter Attachment is the catalog's second-best seller. Jim is the reason we have more than one way to handle a losing gamble.

Dale Castellan

Director of Predictive Alerts

Dale Castellan

Dale built the Telemetry Module. The reason you get a haptic alert four to twelve seconds before a likely event is Dale's statistics work. He does not carry a smartphone on weekends, which is the highest compliment we can pay the product he built.
