   Can't answer your question but I've fought this battle with HD before. They keep the pipe in the plumbing aisle and the fittings in the garden center. Of course the other store has the pipe in the garden center and the fittings in plumbing.

   Did you try the "all purpose"

   Did you try the "all purpose" cement?  (in Oatey it is the red can). That seems to glue a lot of different stuff together.

   Yup...looks like it wont bond it

   The AP cement seems to bond just about eveythign else, CPVC, ABS, etc, but not HDPE.

   ProPoly

   Propoly glue says it will work. I would probably test some Lexel first.

   My understanding is that HDPE is resistant to most solvents and won't solvent-weld very well.  Of course, the two-tone stuff may have the outer layer made of something else that's more easily joined -- I think someone needs to dig into the specs for the stuff.

   It might use pvc fittings

   It's possible to put a pvc coating onto the hdpe.  This would give you the lower cost of hdpe, with the convenience of pvc. 

   Not sure if that is what you are seeing though.  Did you ask the clerk?  If you get a brand name the manufacturer may have an online manual for the stuff.

   HDPE (PPR) ??

   I was investigating this as I purchased several sticks for my hydroponic system. I may be wrong but this may be a type of PPR Pipe. According to the article I read PPR must be heat welded, PVC will deteriate after time espeacially with heat. PPR will not. If any knows If this is corect PPR and HDPE are not concidered like materials please correct me. When I purchased these Pipes the retailer did not know how it was suposed to be bonded (Red Flag) I figured Id find a bonding agent myself. I am just about to assemble my project. I appreciate the info here it will save me some trial and error. with some glues. For now since my system is not pressureized and will be visable and accessible I figured I'd try Silicone first it will allow me to take it back apart if I want to change anything, If this doesnt work I'll use my old stand by JB WELD or PC7 (11). The main reason I chose the HDPE to begine with was because it is none toxic and souldn't have negative effects on growth. (I know the Glues and silicone will to a small degree). ABS is none toxic too (don't know about the glue) but the price is terrible. I would like to know more about the heat bonding of this material if anyone has learned anything, I just don't know why the store would sell HDPE Pipe with out knowing how to bond it. I know this post is old but...

   See that last one especially -- the application is listed on the package.

   rubber boot with band clamps.

   PE and HDPE professionally joined by welding.  For low pressure, hot glue gun works also.

   Like dan said, pe and hdpe does not solvent weld, anything that sticks to it is vanderwall dependent.
