What EST Group, Inc. does
EST Group, Inc., founded in 1968 and headquartered in Hatfield, Pennsylvania, designs, manufactures, and services engineered products for shell and tube heat exchangers, condensers, coolers, and chillers. The company operates as a wholly-owned subsidiary of Curtiss-Wright Corporation (NYSE: CW), organized under Curtiss-Wright's Valves Division within the Naval and Power segment, with regional offices in the Netherlands and Singapore and a global representative and distributor network.
The product portfolio centers on mechanical tube plugging and hydrostatic pressure testing. Flagship Pop-A-Plug® Tube Plugs are positioned as the industry's leading mechanical tube plugging technology for sealing leaking and degraded heat exchanger tubes, supplemented by GripTight® Hydrostatic Test and Isolation Plugs rated for working pressures up to 15,000 PsiG (1,034 BarG), the Smart Ram Plus real-time tube plug installation system, and a Specialty Tools line. Revenue is generated across three streams: hardware sales of tube plugging products, hardware sales of pressure testing and isolation plug equipment, and on-site field services covering tube sleeving, plugging, pulling, testing, inspection, hydro testing applications, and on-site training. Pricing is quote-based and not publicly disclosed.
The company serves six named verticals — power generation (designated primary), oil and gas production, petrochemical and refining, modular plant construction, shipbuilding, and design and build projects — selling through an enterprise direct field sales motion backed by a global rep and distributor channel. Recent operational signals include an August 2025 Bronze Award for Operational Growth and an August 2025 Training for Future Success workforce development initiative. Sister brands within the Valves Division include Dyna-Flo and Farris Engineering.
