Press-Seal

What Press-Seal does

Press-Seal Corporation is a Fort Wayne, Indiana-based manufacturer of rubber gaskets, manhole connectors, and sealing solutions for underground infrastructure, founded in 1954 and now in its third generation of family ownership. The company designs and produces manhole boot connectors (including the proprietary PSX: Direct Drive, PSX: Nylo Drive, CAST-A-SEAL, Econoseal, and Kwik Seal lines), concrete pipe gaskets, corrugated HDPE and PVC pipe gaskets, manhole coring machines, and rail/transit fasteners, plus butyl sealants, lubricants, and wraps added through the 2021 acquisition of Indiana Sealant and Adhesives (INSEAL). Manufacturing capabilities span in-house rubber extrusion, thermoplastic molding, rubber molding, precision tool and die, and metrology services, operated from a 300,000+ sq ft Fort Wayne facility and a second Elkhart, Indiana site, with products certified to ASTM, NSF/ANSI 61, CSA, and ISO 9001:2015 standards.

The company sells primarily to precast concrete manufacturers, contractors, engineers, and supply houses, with end demand driven by stormwater, wastewater, waterworks, and rail/transit infrastructure projects across the United States and Canada. Go-to-market is B2B direct sales via eight territory managers supplemented by an independent rep firm (JLG & Associates) in the Southern/South-Central US, with pricing handled through quote-based contracts and no online retail channel. Revenue is generated from hardware sales across its sealing product portfolio and supporting custom manufacturing, tooling, and metrology services, with installation accessories (lubricants, sealants, calibrated installation wrenches) reinforcing recurring revenue on each installed base.
