PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). <br />2. OD of PEX, copper and CPVC pipe with the same size (CTS) is the same. This is why push fittings can be used with all of these pipes. <br />3 PEX made to US standards must comply with a SDR-9 (Standard Dimension Ratio), which is the ratio of OD (Outside Diameter) to pipe wall thickness <br />(9:1). Exceptions are nominal sizes 1/2" and below. <br />1 Maximum working pressure indicates highest anticipated operating pressure. <br />2. Pressure testing requirements and procedures should be in compliance with local codes and PEX manufacturer's instructions. <br />3 Air pressure testing is recommended over water for practical reasons and due to difficulties arising from water freezing during winter months. <br />4 Since PEX is a flexible pipe, it will expand somewhat (especially PEX-a) during the initial pressurizing of the system, causing a drop in pressure reading. <br />Some manufacturers recommend conditioning" of the system, or allowing the PEX system to stay pressurized for about 30 minutes prior to taking a <br />reading. <br />5. For concrete slabs, pressure is maintained at 30 psi during the pour and Is monitored to assure integrity of the system. <br />0.097" <br />s WALL <br />3/4" <br />z v 0.070" <br />' WALL <br />3/8" <br />PEX Tubing Technical Specifications and General Installation Recommendations <br />Since all PEX tubing used in the US is manufactured to the same ASTM and dimensional (SDR) standards. <br />Manufacturing tolerances and other details can be found in manufacturers' manuals. <br />. 0.083" <br />WALL <br />s/r
