Defrost hoses.
 

I got some new defrost hoses a while back, there real sticky material and i'm having a bit of a time getting them slid over the heater box outlets and plastic vents.

I don't know what this material is but i am looking for a way to lube them up so they slip on instead of fighting them but not so badly that they will pop back off on there own.

After i got these i found out that there are 2 different typed of material used so maybe i should have gotten the other stuff??

I have not run into this problem but If you lube the hoses they may slip on and then slip off. I would try a hairdryer and heat the hoses up a little before trying to install them.

If you do go the lube route and get them on, black electrical tape can be used to tape them to the tubes.

i used heat and they always went on an stayed in place// you could try a little bit of water on the plastic cause it will not leave a residue

There not the plastic ones there like a sticky tar paper similar to the originals.

Can i ask, where did you get the hoses for the defroster? Can i get something similar from home depot or lowes? Gotta put some in my truck since for some reason the last owner decided that since the heater was gone and they put in a stereo that they didn't need to put them back in ----___----

heater box and dash vents are plastic

I would try some black rtv silicone...slippery to install,and once it dries it will hold them on

Re: Defrost hoses.
 

I would suggest using talcum powder (baby Powder) to get the hoses on. It will limit the stickiness, but not provide lasting lubrication. Just be careful the first time you blow air through the tubes because there will likely be a cloud of powder. I used this method for the silicone heater tubes in aircraft.

If they have the metal spiraled wire in them rotate them like your turning a screw to thread onto the heater box outlets, then sick them through top opening of dash, I know its a stretch but they'll stick through the top and rotate the round vent on and then form the other hose to the oblong shape and by wiggly it some you can get the metal spiral past the tabs designed to hold it on. I generally pry with the nubs of my fingernails on the last oblong one. About a 5 minute install using this method.

So by twisting them are you actually expanding the coil wire? Thanks!

I can give it a shot soon, right now my truck is still on jack stands on 4 corners and i don't wanna hop inside.
