TWOB/TBOB/TWOBHV/TBOBHV Series

TWOB TBOBChemfluor® PTFE Fluoropolymer Helically Convoluted Inner Tube
Stainless Steel Braid * Open Pitch

TWOB (white innercore) and TBOB (anti-static, black) innercore were designed to be the optimum in PTFE hose constructions. The tube is formed from a solid homogeneous PTFE extrusion, no tape lamination here. The internal convolutions are shaped to ensure pure flow, absolutely 100% cleanable.

The Chemfluor® PTFE is much thicker than most conventional hoses. This extra thickness gives TWOB and TBOB superior vacuum ratings and hoop strength, easy to flex yet won't flatten when bent, and are extremely crush resistant. A primary advantage of a thick tube design is its ability to be extended through the fittings and flared over to form a sealing face.

This eliminates any joint between fitting and hose. Flow is uninterrupted and the assembly is completely free of areas where corrosion or bacteria can start, pressure drop through the fitting is minimal, cleanliness is assured.

Standard braid material is type 316 SS.

* Burst pressure ratings at ambient 70°F (21°C). See applicable notes below on vacuum/pressure ratings at temperatures other than ambient.

Working Pressure is given @ 70°F. Decrease working pressure 1% for every 2°F above 212°F.

Vacuum rating is given @70°F @ 2X minimum bend radius; decrease vacuum rating 1% for every 2°F above 250°F. Vacuum rating decreases when installed @ lessthan 2X minimum bend radius. TWOBHV/TBOBHV Series (heavy duty vacuum option) allows full vacuum ratings for 1-1/2", 2" and 2-1/2" sizes up to 350°F; decrease vacuum rating 1% for every 2°F above 350°F. Vacuum rating @ less than 2X minimum bend radius:1-1/4" = 26"Hg; 1-1/2" = 25"Hg; 2" = 20"Hg; 2-1/2" = 17"Hg; 3" = 20"Hg; 4" = 17" Hg.

Extended Service Life Tip: Flexible Components suggests using full length "anti-kink" armor casing or at least 16" to 24" long "anti-kink" cuffs at each fitting end to help reduce the strain on the crimp collar and fittings in high load installations. Prolonged service at elevated temperatures will reduce total service life.
