Synflex tubing (formerly known as Dekabon or Dekoron 1300) is a unique lightweight composite-wall tubing designed for low-pressure pneumatic systems and air gauge lines. It is perfect for use as discharge tubing in fire suppression systems.
A thin aluminum inner layer is covered with a thick plastic outer layer. This combination provides the strength and rigidity of aluminum tubing with the light weight and corrosion resistance of plastic tubing. It is also considerably less expensive than tubing manufactured of corrosion resistant metal. Synflex can be bent by hand (no special tools required), but it will hold its shape like metal tubing. It can be easily cut with a tubing cutter, wire cutters, or even a shop knife (expect to replace the shop knife blade after cutting this tubing).
Available in nominal outside diameters of 1/4", 5/16" (8mm), 3/8" (10mm), 1/2", and 6mm. Operating temperature range -40° to 80° C (-40° to 176° F). Pressure rating varies with tubing size and temperature. The lowest operating pressure rating (1/2" at 80° C) is 100 psi.
SPA Halon fire systems used the 1/4" size.
SPA AFFF fire systems use the 6mm size.
SPA FIA18 AFFF fire systems use the 5/16"/8mm and the 3/8"/10mm sizes.
SPA FIA19 AFFF fire systems use the 6mm and the 5/16"/8mm sizes.
SPA Extreme Novec 1230 fire systems (green bottle) use 6mm (SP 015), 8mm (SP 032), 10mm (SP 072), and 12mm (SP 081) sizes.
OMP Platinum Series (0.9L and 1.3L) use the 6mm size (CD/323/N/6) and 5/16" / 8mm size (CD/323/N/8).
Not recommended for constant handling of fluids or pure oxygen. Synflex is appropriate for brief exposure to fluids, as in fire system discharge lines.
