SDR is the short form of Standard Dimension Ratio
Quality Assurance & Health SDR = Diameter / Wall Thickness
Certifications SDR = d /s = Pipes series index from ISO 4065
Ethylene Vinyl Alcohol (‘’EVOH’’) Oxygen Barrier with excellent gas barrier
properties that limits oxygen diffusion through the walls of the tubing.
Designed to be compatible with PEX and EVOH layers and creates a superb
adhesion between layers
A high-temperature flexible plastic pressure pipe with a 35 year history of
successful use in the European market with extensive testing for
durability and material performance, made of cross-linked high density
PEX .
