About this file
This document is a technical drawing set for a Standard Bubbler Orifice Assembly produced by NOAA's National Ocean Service (NOS) Center for Operational Oceanographic Products and Services (CO-OPS). The complete assembly consists of three sheets detailing the cover sheet, part details with dimensional specifications, and an item list.
The assembly comprises six components manufactured from 90-10 copper nickel (UNS C70600) except for one specialized fitting. The primary components include a bottom parallel plate (3/16" plate), three spacer rods (3/8" diameter), a top parallel plate (3/16" plate), an orifice body end cap, and a 2-inch NPS orifice body. All copper nickel parts are welded using 70-30 ERCuNi weld rod. The sixth item is an Alloy 400 (Monel 400) 1/4 NPT to 3/8 tube Swagelok fitting (PN# M-600-1-4). Dimensional tolerances are specified as ±1/16" for fractions, ±0.03 for double-decimal measurements, and ±0.010 for triple-decimal measurements, with angular tolerances of ±0.5°. The drawing was initially created as historic documentation and underwent revision A on 3/10/2026 to update tolerances, fits, and specify the Alloy 400 Swagelok component. All measurements are in inches, and the drawing is not to be scaled.
