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.
