WARNING: Cancer and Reproductive Harm -


I use the J3400-2 with Tygon tube. Once the tube is pushed on it is there to stay. No hose clamps required. You have to carefully cut the Tygon tube to remove the tube from the J3400-2. Extremely difficult to just pull the Tygon tube from the J3400-2. No leaks. Would recommend these for pitot static lines with Tygon tube. This is mainly what I have used them for. However I have also used these with Tygon tube up to 50 PSI, with no problems and no hose clamps. Well made hose end.

Used these fittings for my vacuum powered instruments. Made removal for future servicing much easier.

Appear to be excellent product except the barbs are so big I could hardly get the Helix tube over them.
