🔖 Art. ML3D_0004 Parametric BSP × Barb hose fitting by MarineLab3D. Customizable male BSP threaded fitting with 3-barb hose tail for rubber hose — designed for 3D printing in PETG or PA12. 🔧 Thread size : BSP 1/8" to 1" (6 sizes, DIN hex auto-calculated) 🔩 Hose inner diameter : 6 / 8 / 10 / 12 / 16 / 19 / 25 mm 🪝 3 barbs : 25° entry ramp + 90° vertical lock wall 🔑 Hexagonal wrench flat automatically sized per DIN 2999 (SW14–SW41) 📏 Adjustable hex body height: 10–200 mm — from a standard fitting to a long hex extension/standoff 🛠️ Chamfered barb-to-hex transition — smoother flow and a stronger junction 🛡️ Print in PETG or PA12 for saltwater & fuel resistance ⚙️ Tap thread after printing with BSP G tap for precise sealing Compatible materials: PETG · PA12 · CF-Nylon · ASA Note: BSP thread profile is approximated (circular teeth). For pressure applications, tap with a BSP G die after printing or use a brass insert. License: MarineLab3D Original — All rights reserved ⚠️ PRESSURE USE (above ~1 bar): print in PETG (not ASA — better layer sealing), with SOLID walls (enough perimeters to fully fill the wall thickness — do not rely on infill), Z-seam set to “Scarf joint”, low part-cooling fan, flow +2–3%, and the thread/seam axis VERTICAL. Most onboard plumbing systems run at max ~3 bar: at this level these print settings + a GENEROUS amount of PTFE tape / thread sealant on the threads are enough. Always pressure-test at ~2× working pressure before use. Only for pressures above ~4 bar: also brush a thin coat of epoxy resin inside for a guaranteed seal. A 3D-printed fitting is a valid solution but always verify it for your specific application. 🖨️ No 3D printer?
