Family Owned and Operated Since 1974

Knisley Welding, Inc. has been serving the aviation community since 1974. Aircraft exhaust systems have always been difficult to find and a problem to maintain. Knisley Welding, Inc. was formed to fill that need. We started our business in repair and moved into manufacturing. Our extensive inventory and quality service provides exhaust components to owners, operators, and repair stations throughout the world.

We carry parts for Cessna, Piper, Beech, Mooney, Bellanca, Partenavia, Bell and Helio brands. We are even approved to sell modified aircraft exhaust systems for Cessna.

Our complete parts department has hundreds of FAA/PMA approved parts on the shelf and ready to ship. View our online catalog and call to place your order. If you have any other questions, fill out our contact us form or give us a call.
