Smooth Bore Hose applications
Smooth Bore Overview

Smooth Bore PTFE hose is capable of carrying a wide range of difficult-to-handle media such as chemicals, steam, solvents, inks and dyes, paint, injectable materials and plastisols.

It is used for a variety of applications such as sanitary transfer, bottle filling, gas analysis, extrusion presses and molding/adhesive conveying.

The temperature ratings for this king of hose are quite broad: -65°F to 450°F.

PTFE smooth bore hose is kink resistant with improved vacuum ratings and damage resistance. It cleans easily with steam, detergent or caustic and can be autoclaved.


CONSTRUCTION
  • Inner Core vertically extruded to maintain highest quality concentricity.
  • Manufactured from PTFE fine grade resin.
  • 304 stainless steel wire braid reinforcement.
  • An exact amount of carbon black added to the PTFE inner core provides continuous conductive path to the metal end fittings, to bleed off static electricity in steam or high flow rate applications.
TEMPERATURE RANGE
  • For continuous service: -65°F to 450°F (-54°C to 232°C)
  • For intermittent service: -100°F to 500°F (-73°C to 260°C)
STANDARDS
  • Meets or exceeds requirements of SAE 100R14
  • PTFE meets FDA 21 CCFR 177.1550
VACUUM SERVICE
  • Sizes -4 thru -10 are rated for full vacuum.
  • Larger sizes -12 and above can be reinforced with an internal support spring for full vacuum service.
