What Koul Tools does
Koul Tools LLC, founded in 2005 and headquartered in Lake Havasu City, Arizona, is a privately held, founder-owned specialty tool manufacturer with 1–10 employees. The company designs, patents, and sells mechanical tools for hose assembly and flare-fitting repair across automotive, motorsports, industrial, aerospace, and medical-device end markets. The founder and inventor, Dick Raczuk, developed the core product family after encountering a leaky brake-line fitting on his Packard Coupe, and continues to handle customer-service and technical support directly.
The product portfolio is organized around two technology pillars. The first is the patented lead-screw hose-press family, comprising the EZ-ON Hose Press Models 426, 427, 454, and 223 (handling push-lock and barbed fittings from 1/4" to 3", priced $399–$2,495) and the AN Hose Assembly Tool ($30–$150), which uses a high-tech composite capsule to funnel braided stainless-steel hose into AN fittings in under ten seconds. The second is the diamond-dust lapping technology, embodied in the Surseat flare-lapping tool family (P-51B, P-45, P-37; $60–$150) and the Fitting Fixer ($39–$200), both protected by US patents (US 9,943,942 B2, US 9,878,429, US 7,818,856). An add-on Nylon Fuel Line Tool ($80–$445) and $2.50 replacement adapters complete the catalog.
The business model is straightforward one-time hardware sales with no recurring or subscription revenue. Products are sold direct via koultools.com (with free shipping on orders over $99 in the continental US) and through a multi-tiered dealer channel covering 25+ US specialty retailers (Summit Racing, Jegs, Speedway Motors, Aircraft Spruce, Pegasus Auto Racing, Van's Aircraft, Kartek Off-Road, among others), Canadian distributors (Regional Hose, JBs Power Centre, Dix Performance North), and a European partner (ISA-RACING GmbH, Germany). Pricing is fixed unit pricing; average selling prices are low, with the customer base spanning both individual/SMB buyers (hot-rodders, custom chassis builders) and large enterprises (Ford, GM, Tesla, NASA, US Navy, Pratt Whitney, Boeing-adjacent MROs, Coca-Cola, Pepsi, Caterpillar, Parker, Bosch, Boston Scientific).
