✅ Use Recommendations

  • For 1/8″ or 1/4″ thread needs with 4 mm tubing, PU04 variants from Factorysupplies offer simple, low‑cost options and are typical in hobbyist/compressed air setups.

  • For M5 thread, choose based on requirements:

    • Standard brass (PC04‑M5) is cost‑effective and easy to find.

    • Stainless‑steel (PC04‑M5L) if you need higher temperature / corrosive resistance.

    • Aignep etc. if you plan many reconnections and need durable grip.

    • Festo QSM‑M5‑4 if space is tight and your system handles up to ~14 bar.

ℹ️ Additional Info from User Discussions

  • Many users in 3D‑printing / pneumatic forums refer to these as “PC4‑M5” fittings—used for 4 mm PTFE tubes with M5 metric ports. Some people interchange “PC4” with PC04 naming

  • When used in 3D printer bowden setups, some note that the threads are actually 1/8″ BSP, but commonly marked as PC4‑M6 or M5 based on tubing and hotend thread mismatch

  • Festo fittings are often recommended by users seeking better longevity versus generic cheap parts Reddit+1Reddit+1.

🧰 Summary

  • 1/8″ male to 4 mm tube: PU 05xx series, brass/push‑in, around R20–30.

  • 1/4″ male to 4 mm tube: same series with 1/4″ thread variant.

  • M5 male to 4 mm tube: PC04‑M5 style; choose brass or stainless based on environment and pressure/temp needs. Festo and Aignep versions add added durability and narrower profiles.
