Q – What is HDPE?
A – HDPE is the abbreviation for High-Density Polyethylene.

Q – What is PE4710?
A – PE4710 is a high-performance grade of HDPE resin. PE4710 has a longer calculated service life, greater resistance to chemicals and a 25% higher pressure rating than comparable PE3408 products.

Q – What is SDR?
A – SDR is an abbreviation for Standard Dimension Ratio. This is ratio of the inside diameter (SIDR) or outside diameter (SODR) of the water pipe to the wall thickness of the water pipe. The smaller the SDR number the thicker the wall of the pipe or tubing. SODR refers to pipe or tubing that is OD controlled. SIDR refers to pipe or tubing that is ID controlled.

Q – What is the warranty on EndoPure HDPE?
A – Endot provides a Lifetime Warranty on NSF Certified EndoPure HDPE. See downloadable EndoPure Warranty document.

Q – Will EndoPure HDPE rust or corrode?
A – No. HDPE is almost chemically inert and does not rust or corrode. EndoPure HDPE pipe carries a Lifetime Warranty against rust, rot and corrosion.

Q – Does EndoPure HDPE get brittle when cold?
A – No. HDPE does get harder and stiffer when cold, but HDPE does not get brittle like some plastics.
