AUFishGuy April 18, 2017 Share April 18, 2017 (edited) The barb fitting that connects my vinyl tubing to the pvc of my return has slow leak where the vinyl fits on the barbs. What can I do about this? Can I put silicone or pvc cement on the barbs? Any advice is appreciated. Edited April 18, 2017 by AUFishGuy Link to comment Share on other sites More sharing options...
Origami April 19, 2017 Share April 19, 2017 I'll use zip ties on barbs to tighten up the connection. You can also use a hose clamp, but metal ones rust. Sent from my LG-V510 using Tapatalk Link to comment Share on other sites More sharing options...

WheresTheReef April 19, 2017 Share April 19, 2017 I use the ratchet clamps http://www.bulkreefsupply.com/ratchet-clamp-for-tubing-1-6684828461f4e5bda1e2a33b5e0db6d3.html Link to comment Share on other sites More sharing options...
zygote2k April 19, 2017 Share April 19, 2017 hard pipe that connection and you wont have to worry about barbed fittings, hose clamps, or soft tubing. Link to comment Share on other sites More sharing options...
GraffitiSpotCorals April 19, 2017 Share April 19, 2017 Wrap the Barb thick in Teflon tape and slide the hose over it with a hose clamp, if you have to keep the hose barb fitting. Link to comment Share on other sites More sharing options...
