No glue has been made that makes a satisfactory joint on HDPE. There is a'hot rod welding' process, or gluing with a transition cement AND a screw to ensure no coming apart. -I'd choose a more versatile pipe if I was you.
No, there is no suitable adhesive. These must both have threaded endings and be mechanically attached or use something like a 'Sharkbite'
That's HIGH DENSITY, or HDPE in the plumbing business. Pro-Poly is one of the very few choices for this. The fact is that the group of olefins (polyethylene based plastics), which include LDPE, HDPE, and UHMW, are so chemical resistant that modern science has not invented a solvent glue to bond these plastics.
HDPE= High-density polyethylene
Sometimes
High Density Polyethylene (HDPE)
People who do it usually use glue sticks or Aleenes glue.
You can use white glue or super glue as well.
To calculate the weight of an HDPE pipe, you can use the formula: Weight = Volume × Density. First, calculate the volume of the pipe using the formula for the volume of a cylinder (πr²h, where r is the radius and h is the height), and then multiply it by the density of HDPE to get the weight. Density of HDPE can range from 0.93 to 0.97 g/cm³ depending on the grade.
if it is a plastic model kit you can use super glue, but not wood glue.
you use a non toxic nail glue
You have to use glue of course and you need someone to hold it together while you glue it
LDPE is softest, HDPE is harder, PMMA is much harder than HDPE
