Fluoropolymer (PTFE) Convoluted 316 SS Braided Open Pitch

'HV' Option for Vacuum Service Fully Rated Vacuum Hose TWOBHV/TBOBHV. HV versions are recommended for "full vacuum" applications and always for 2 1/2", 3" and 4" assemblies.

Description:

TWOB (white inner core) and TBOB (anti-static, black) inner core 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% totally 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.

 

Chemfluor ® PTFE Tube:
  • Unexcelled chemical resistance.
  • Compatible with all materials.
  • Rounded, open-pitch, helical convolution design.
  • Easy to clean; self cleaning.
  • Non-stick Chemfluor® PTFE Tube can be cleaned with steam, caustics, solvents, or other cleaning agents.
  • Assure sterility.
Fittings: "Flare-Thru"

Integrally lined 'through the fittings' in flanged, female cam and groove and sanitary clamp designs-1/2" mini-sanitary Flare-Thru also available. For availability, Contact Us.

"Crimp Style"

Over 36 styles of 316L SS conventional fitting designs can be mechanically attached 360° Radial (crimp).

"Anti-Static" Inner tube

These hoses are designed to safely convey electrically resistive fluids such as solvents, certain hydrocarbon based fuels, freons and even steam.

Temperature Rating:

-73°C(-100°F) to +232°C (+450°F)

Specifications

Measured resistance does not exceed 106 in accordance with hose specification DIN 2823 American National Standards Institute (ANSI) C59.3-1968 ASTM D257-72; British standard BS2050; 1978.
