CHENGSHUO | ENGINEERING CONCEPT REVIEW Reference concept: Retained hose-tail stem Page: https://chengshuoprecision.com/components/shafts-and-pins/retained-hose-tail-stem/ Our component / drawing revision: [ ] Assembly and mating interfaces: [ ] Please review: 1. Stem drawing and selected tube specification 2. Receiving-device and retaining-part interfaces 3. Material, finish and internal-edge requirements 4. Quantities, assembly method and validation responsibility Sample acceptance to agree: 1. Tube-contact profile: Define barb crest, entry lead and working length against the chosen tubing. 2. Device-side retention: Specify the shoulder, groove and mating retaining element. 3. Passage and edges: Identify flow-path geometry, accessible edge checks and cleaning requirements. 4. Assembly validation: Agree tube attachment, leakage and retention tests for the completed connection. Material grade / finish: [ ] Sample / production quantities: [ ] Target timing / delivery destination: [ ] AI-generated engineering concept, not a production photograph or completed delivery. Feasibility, process route and acceptance criteria require review of our actual drawing.
