700 Series

Our original general purpose hose, 700 series is a high quality hose that has long served the traditional industrial sectors. While P4 series, which is manufactured using a different, more modern corrugation forming process, is the “new generation” of 700 series, specifications calling for 700 series remain.

To make 700 series, we begin with a cylindrical tube formed from rolled strip and joined at the seam by butt welding. Impressed into this tube is a corrugated annular profile. Our manufacturing process produces long lengths, which are packaged in standard cartons or as braided hose-on-reels.

American Iron & Steel (AIS) Compliant Options

For projects with 100% domestic sourcing requirements, Penflex offers AIS compliant versions of P4 and 700 Series hose and braid. While AIS requirements apply specifically to water infrastructure projects, products manufactured to AIS standards may also support broader domestic sourcing initiatives, including Build America, Buy America (BABA) and Defense Federal Acquisition Regulation Supplement (DFARS).

AIS requirements mandate that:

Stainless steel strip used to form hose is melted and produced in the United States
Stainless steel wire used for braid is melted and drawn in the United States
All manufacturing processes take place domestically
