What Gasket and Seal Fabricators does

Gasket and Seal Fabricators (GSF) is a precision gasket and seal manufacturer founded in 1977 and headquartered in Sauget, Illinois, within the St. Louis metropolitan area. The company produces custom-fabricated gaskets, seals, and O-rings for industrial B2B customers across medical, electrical, aerospace, HVAC-R, oil & gas, railroad, motor and compressor, water purification, and vending equipment manufacturing. GSF operates a dual business model: custom fabrication (die-cut, knife-cut, lathe-cut, extruded, molded, and spliced gaskets with cutting tolerances as tight as plus or minus 0.005 inches) and authorized distribution of branded materials from Parker Hannifin, KLINGER Thermoseal, Garlock, Interface/Alkegen, Rubberlite, and Rogers Corporation. The company employs 11-50 people and runs an AS9100:2016 (certified October 2024) and ISO 9001:2015 quality management system.

The technical foundation rests on in-house converting equipment for slitting, laminating, and vulcanizing, paired with material expertise spanning commodity elastomers (nitrile, EPDM, silicone, neoprene) to high-performance compounds (FKM and FFKM fluorocarbons, PTFE, fluorosilicone, polyurethane, cork nitrile, PORON microcellular foam). GSF holds FDA 21 CFR 177.2600 compound compliance for food-contact applications and UL 94 flammability ratings across multiple product lines. Customer value propositions emphasize on-time delivery against just-in-time production schedules, rapid quote turnaround, and supplier scorecard performance, supported by 45+ year KLINGER and 25-30+ year customer relationships documented in testimonials.

The revenue model is quote-based unit pricing on custom orders, with a standard 2-3 week lead time and a 5 business-day expedite option. Distribution is direct B2B (phone, email, website quote forms) with no public pricing. In December 2025, GSF acquired Seal Tite Corporation, a St. Louis-based gasket, seal, and O-ring manufacturer founded in 1947, marking its first disclosed M&A and signaling a strategic consolidation phase under new leadership that is investing in equipment modernization and process improvement.
