Hi Patprimmer,
Usually a rubber suction hose is reinforced with steel helix wire to handle vacuum, the problem with steel is if the hose is crush the hose become unusable because the hose will not go back to its original shape. We are working to do a rubber suction hose reinforce with plastic...
Does anybody know a good plastic rod and supplier to reinforce a rubber hose to make it crush resistant. We tried some PET and PBT resins but we have still not found the good one yet
Thank you
