Corrugated Metal Hose and Braid Specification Guide.

Whether you prefer fabricating thin wall, medium wall, or heavy wall hose, Penflex has a series of hose available. Typically our heavier wall thicknesses provide for easier welding and longer resistance to chemical corrosion. Our manufacturing process produces long lengths which are packaged in standard cartons or as braided hose-on-reels.
We have EIGHT different Series of Hose listed above. To view Technical Specifications for a hose, just follow these two simple steps:

  1. Choose a Hose Series above;
  2. Select a size of the hose you are looking for.
