Light-Weight rigid Ducting that can incorporate thermal and acoustical insulation to operate reliably in a wide range of temperature conditions. They are some of the lightest products in the industry!

Flexible Ducting: Low pressure flexible ducts for positive and negative air pressure that operate in a wide temperature range.

Custom designs: Round to rectangle, we offer tapers in variable dimensions.  Designed and built to your custom requirements.

Hoses: Lightweight, low pressure hoses designed and built to your specifications.

Insulation: Multiple options are available to meet any R-value and thickness requirement.

Tapers and Variable Diameters: Transition between different diameters seamlessly over varied lengths.

Bellows: Ideal for high pressure applications. Offered in bonded, clamped or crimped fittings. Customizable for individual offset and extension requirements.

Silencers/Mufflers: Flexfab can manufacture a custom silencer for your noise reduction needs.

Locomotive Assemblies

Flexfab’s selection of locomotive assemblies include:

• Charge Air Turbo Ducts
