Installation Recommendations <br />Since all PEX tubing used in the US is manufactured to the same ASTM and dimensional (SCA) standards, these specifications are universal. <br />Manufacturing tolerances and other details can be found in manufacturers' manuals. <br />Dimensional data and specifications <br />PEX Tubing size <br />(015/Nominal) <br />Outside Diameter <br />(OD) Minimum wall thickness Inside Diameter <br />(ID) Volume ga1/100ft Weight lbs/100ft <br />318" 0.500P 0.070" 0.360" 0.50 4.50 <br />1/2" 0.625" 0.070" 0.485" 0.92 5.80 <br />5/8" 0.750" 0.083" 0.584" 1.34 8.38 <br />3/4" 0.875" 0.097° 0.681" 1.83 11.00 <br />1" 1125" 0.125" 0.875" 3.03 17.06 <br />and non-barrier PEX. .ua,a a sunecr to manuractUnng tolerances end may vary by brand. Same data apples both to oxygen barner <br />Notes: <br />I. PEX tubing sizes are denoted by CTS (copper tubing size), not OD (Outside Diameter) or ID (Inside Diameter). <br />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 />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 />Pressure ratings, testing and pressure drop <br />PEX Tubing <br />Pressure Ratings Pressure testing. Hydrontc & Radiant Heating Pressure testing.
