Gortiflex® Bellows

Dynatect’s Gortiflex completely sealed bellows are constructed from a tube of elastomer with optional fabric reinforcement that is formed and vulcanized into a sealed cover with high-cycle durability for a wide variety of challenging applications.

This construction method allows for the use of multiple material selections and design attributes, while keeping costs relatively low compared to other solutions.

The elastomer and optional fabric can be engineered to be compliant to medical, high and low temperature, food-grade, outdoor, or other specialty applications.  A zipper can be added for easy installation, internal guides can be added for bellows intended to protect spinning shafts/screws.

The standard shape is round but other shapes are possible with low-cost tooling (significantly less expensive than traditional molded bellows tooling).  This allows for fast, customized, low volume production and prototypes with small upfront costs.
