The Sealing Connection Tooling Partner for Manufacturing
FasTest designs, engineers, and manufactures sealing connection tools, the connectors, fixtures, access ports, and automated systems that manufacturers use to leak test, pressure test, fill, evacuate, charge, and transfer fluids on production lines and in field service operations around the world.
Our products solve a problem that exists in virtually every manufacturing environment: the need to make a fast, reliable, repeatable sealed connection to a port, thread, tube, valve, or surface, thousands of times per shift, without the false failures, operator injuries, and wasted cycle time caused by traditional threaded connections, clamps, pad seals, and improvised tooling.
FasTest serves seven major industries, automotive and EV, HVAC-R, compressed gas, fluid power, medical and life science, aerospace, and appliance, with an extensive line of standard products covering hundreds of port types, plus a custom engineering team that has completed thousands of bespoke connector and fixture designs. Our ICON™ Intelligent Connection Technology brings digital seal confirmation and process automation capability to the product line, and our system solutions, including the EvacMax™ automated evacuation cart and Engine Test Packages, deliver complete, turn-key tooling for complex applications.
Headquartered in the United States and supported by a global distribution network, FasTest has been solving sealing connection challenges for over 40 years. We are ISO 9001:2015 certified, patent-protected, and backed by a technical support team that stands behind every product for the life of the equipment.

ICON™ Technology
Intelligent Connection Technology Available for Many Connectors
ICON™ is FasTest’s process automation platform, available across a growing range of leak test connectors and sealing tools. By integrating sensing, SURE SEAL™ seal confirmation, and real-time data output directly into the connector, ICON™ transforms every connection point into an intelligent data source.
With ICON™, your test stations gain the ability to verify that a leak-tight seal has been achieved before the test cycle begins (eliminating false failures), confirm that each connection step in a multi-port sequence has been completed (enabling automated handshakes), and output real-time connection status data for traceability, SPC, and process optimization. Whether your lines are manual, semi-automated, or fully robotic, ICON™ adds the intelligence that modern manufacturing demands.
