These hump connector hoses have a 25mm ID to provide a flexible coupling between two 1" OD tubes.  The 3-ply reinforcement results in a 4.5mm wall thickness (34mm / 1 3/8" OD) and a working pressure rating over 39 psi (199 psi burst pressure).  Overall length 4" (102mm). Use with our Lined Hose Clamps (Part No. 3613-1.75).  
  
  
  
  Silicone hose is for use on intake systems only.  It is NOT for use on exhaust!  Exceeding the temperature rating of 356°F will destroy it.
