Polyethylene tubing designed to match the outside diameter of copper tubing.
ASTM D-2737 (SDR-PR) Based on Controlled Outside Diameter
This specification covers polyethylene pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water at 73.4°F. Pipe manufactured under this specification is based on a controlled outside diameter which is designed to match and mate with copper tube using copper tube size (CTS) compression couplings.
Pipe manufactured to this specification is described using a prefix-diameter ratio. The prefix for ASTM D-2737 is SDR.
The most common ratio under this specification is SDR-9. The definition of SDR (Standard Dimension Ratio) is the specific ratio of the average specified outside diameter to the minimum specified wall thickness.
SDR-9 service tubing is available in black as well as black with a blue stripe.
