numbers and Xem-drawn envelopes\nCatalog version: 2026-10-20\n\nSizes: see table below\n- B16.11 threaded fittings (NPT per ASME B1.20.1): B is the minimum length of perfect thread, J the minimum length of useful thread (B plus threads with fully formed roots and flat crests), D the outside diameter of the band, G the minimum wall and A the centre-to-end of a 90° elbow or tee; C is the 45° centre-to-end. Wermac's page itself defines only B and J and orders the other columns by header position, so the letter mapping is a reading; it is confirmed by the maker: Smith-Cooper's elbow A and B (inches) equal Wermac's A and D for Class 3000 NPS 1/2 to 4 and Class 6000 NPS 1/2 to 3 within 1.5 mm (NPS 2 Class 3000: A 64 / D 84 mm vs 2.50 / 3.31 in = 63.5 / 84.1). The 'check' column shows the inch comparison.\n- Dropped: Wermac's Class 6000 NPS 4 elbow row (D 152, A 114, C 79) repeats the Class 3000 NPS 4 row exactly, while the Class 6000 rows from NPS 1/2 to 2-1/2 equal the next size's Class 3000 D, A and C (and NPS 3 is 146 / 106 / 79); the value is not used. The maker's 6000 series stops at NPS 3 for elbows.\n- Disagreement shown, not resolved: Class 3000 NPS 3/4 cap OD is printed '35.' by Wermac and 1.33 in (33.8 mm) by Smith-Cooper (all other cap ODs agree within 1 mm), so no 3/4 cap file is drawn. Tees use the same centre-to-end A as the 90° elbow (Wermac's tee table repeats the elbow columns).\n- Class 2000 is Wermac only (no maker cross-check read) and is table-only. Couplings: Wermac's threaded-coupling page was not available; Smith-Cooper's A and B (inches) are shown as printed, but the catalog text does not define which is the length and which the OD, so no coupling file is drawn.\n- Files (Xem-drawn envelopes): cylinders of the published band OD D meeting at a sphere of the same radius at the centre, out to the published centre-to-end; caps are a cylinder of OD D and length A with a plain blind bore of depth J. Threads are plain bores: the bore is the NPT tap-drill size (Ø18.3 for 1/2, Ø23.4 for 3/4, Ø29.4 for 1; from ANSI/ASME B1.20.1 as listed on npt-bsp-thread-envelopes). Taper, thread form and the true outer shape (the real band and hexagon-like body of a forged elbow) are not drawn; those are not published as numbers in the sources read. Sizes are 1/2 to 1 only because the tap-drill table on this site stops at NPS 1.\n- Threaded fittings take male NPT pipe directly (pipe thread sealant, no socket): see npt-bsp-thread-envelopes for the male side.\n\npart class NPS elbow/tee: B min perfect thread | cap: length A elbow/tee: J useful thread | cap: OD D (mm) elbow/tee: D band OD | cap: min wall G elbow/tee: G min wall | cap: B thread elbow/tee: A 90° | cap: J thread elbow/tee: C 45° | cap: — check vs maker (in): elbow/tee A / OD;
