Revision of F3348-23a Standard Specification for Plastic Press Insert Fittings with Factory Assembled Stainless Steel Press Sleeve for SDR9 Cross-linked Polyethylene (PEX) Tubing and SDR9 Polyethylene of Raised Temperature (PE-RT) Tubing
Rationale
Address dimensional conflicts in Table 1: Remove dimension 'E' as it does not control/ refer to any feature. T Min specified is greater than calculated Min Thickness from the allowable diameters. So, make dimension 'B' to be 'Bmin' with the following values: 0.185” for 3/8”, 0.295” for ½”, 0.465” for ¾”, 0.645” for 1”, 0.794” for 1.25”, 0.928” for 1.5”, and 1.221” for 2”. Update dimension 'D' for the 2” size to 1.535”
Address dimensional conflicts in In FIG 1: Left Figure: Remove ‘E’. Address tolerance stack up issue - Max G ? 2* (Max I). Right figure: Remove ‘I’ on the left-hand side. Add Detail view to both sealing barb sets. Rename detail view from ‘PRIMARY SEALING BARB GROUP DETAIL’ to ‘SEALING BARB GROUP DETAIL’
Address material designation conflicts in the Materials section 5.1. Currently the standard calls for polyphenylsulfone blends but the wrong group number. Remove ‘blends’ from the material callout.
