About Nickson Industries

Founded and headquartered in Plainville, Connecticut, Nickson Industries has built a reputation as one of America's most trusted manufacturers of exhaust accessories and engine heating solutions. Every product is engineered and manufactured in the USA, reflecting the company's long-standing commitment to quality craftsmanship and innovative design. Whether you're a professional technician or a dedicated do-it-yourselfer, Nickson's comprehensive catalog is built to meet the demands of real-world vehicle repair and maintenance.

A Complete Exhaust Accessories Lineup

Nickson Industries operates under its Nickson Exhaust Solutions brand, offering one of the most comprehensive ranges of exhaust hardware available in the aftermarket. Exhaust clamps are a cornerstone of the lineup — heavy-duty units featuring reinforced rib saddles and extended U-bolts that deliver a secure, leak-free connection for professional and DIY installers alike. For those tackling a full repair job, Nickson also offers exhaust clamp kits that bundle the hardware you need into one convenient package.

Beyond clamping solutions, Nickson manufactures a wide variety of exhaust pipe adapters — including connectors, reducers, tailpipe extensions, turndowns, and elbows — crafted from aluminized and stainless steel for lasting corrosion resistance. These adapters are essential when bridging mismatched pipe diameters or replacing sections of an aging exhaust system without a full overhaul.

Nickson's hose clamps round out the hardware offering, providing reliable clamping force for a range of underhood and exhaust applications. And for emissions-related repairs, Nickson also carries secondary air injection check valves, ensuring the air injection system functions correctly to reduce cold-start emissions and protect catalytic converter efficiency.

American Engineering, Broad Market Coverage

Nickson Industries serves automotive, light-duty truck, medium and heavy-duty truck, industrial, and off-highway markets. This broad reach means that whether you're servicing a daily driver or a commercial fleet vehicle, there's a Nickson part engineered for your application. The brand also produces catalytic converter gaskets, exhaust hangers, brackets, flexible flange repair pipes, and a full line of manifold hardware — making it a single-source solution for most exhaust system repair needs.

Beyond exhaust, Nickson's sister brand KAT'S Heaters extends the company's expertise into engine block heaters, battery heaters, and circulation heaters — solutions designed to keep engines starting reliably even in the most demanding cold-weather conditions.

Quality You Can Count On

Nickson's focus on intelligent product design, high-quality raw materials, and thoughtful packaging has made it a go-to brand for shop professionals and parts specialists across North America. With a catalog spanning hundreds of SKUs and decades of manufacturing heritage behind each one, Nickson Industries continues to deliver the dependable hardware that keeps exhaust systems — and engines — running right.
