Bulkhead Female Thread Pneumatic Push-In Fittings — Secure Panel-Mount Air Line Connections

Routing compressed air lines through enclosures, machine panels, or control cabinets often means dealing with loose hose connections that vibrate free or leak under pressure. These bulkhead female thread pneumatic push-in fittings are designed for engineers, maintenance technicians, and serious DIYers who need a reliable, panel-mounted air connection that stays put.

Each fitting features a push-in collet on one end for tool-free tube insertion and a female threaded port on the other for secure panel mounting via locknut. Available in tube OD sizes from 4mm (≈5/32") to 12mm (≈1/2"), with multiple thread variants per size (PMF4, PMF6, PMF8, PMF10, PMF12). Constructed from durable engineering-grade materials typically used in industrial pneumatic systems.

Typical applications include pneumatic control panel builds, CNC machine air line routing, automated assembly line enclosures, and workshop air distribution systems where a clean through-panel connection is required.

🔵 Compatibility: Designed for standard pneumatic tubing (PU, PA, PE) with OD sizes 4mm, 6mm, 8mm, 10mm, and 12mm. Thread type varies by variant — see variant options or contact us to confirm thread pitch before ordering.

✅ Key Features of These Bulkhead Female Thread Pneumatic Push-In Fittings

🔩Panel-Mount Bulkhead Design — Passes through enclosure walls or machine panels and locks in place with a threaded locknut, keeping your air lines organized and secure.
⚡Tool-Free Push-In Connection — Simply push the air hose into the collet for an instant, leak-resistant seal — no clamps or wrenches needed for the tube side.
📐Wide Size Range (4–12mm) — Covers the most common pneumatic tube OD sizes used in industrial and DIY compressed air systems, from 4mm (≈5/32") up to 12mm (≈1/2").
🔄Female Thread Port — The threaded end accepts standard fittings or plugs, making it easy to connect to manifolds, valves, or extend your air circuit on the panel side.
🛡️Rated for Typical Pneumatic Pressures — Generally suitable for working pressures up to 10 bar (145 PSI), covering most workshop compressor and industrial automation applications.
🔁Reusable & Reconfigurable — The push-in collet allows the tube to be released and reinserted multiple times without degrading the seal, making these fittings ideal for systems that need periodic reconfiguration.

❓ Frequently Asked Questions

How do I choose the right tube size for my pneumatic system?

Match the fitting's tube OD size to your air hose outer diameter. For reference: 4mm ≈ 5/32", 6mm ≈ 1/4", 8mm ≈ 5/16", 10mm ≈ 3/8", 12mm ≈ 1/2". Always measure your existing tubing OD with calipers before ordering to ensure a proper push-in seal.

What thread standard do these bulkhead fittings use?

Thread type varies by variant. These fittings generally use metric or BSP (British Standard Pipe) female threads. The suffix in the variant code (e.g., -01, -02) typically indicates the thread size. Contact us with your variant code to confirm the exact thread pitch before installation.

Can these fittings be used outdoors or in humid environments?

These push-in fittings are generally designed for indoor pneumatic systems. For outdoor or high-humidity environments, applying PTFE thread tape on the female thread connection is recommended to improve moisture resistance. In most cases, they are not rated for continuous outdoor exposure — contact us to confirm suitability for your specific environment.

What is the maximum working pressure for these fittings?

Pneumatic push-in fittings of this type typically support working pressures up to 10 bar (145 PSI) at normal operating temperatures. Actual pressure ratings may vary by size and material. Contact us to confirm the rating for your selected variant before use in high-pressure applications.

Are these fittings compatible with polyurethane (PU) and nylon (PA) tubing?

Yes. These bulkhead push-in fittings are generally compatible with standard pneumatic tubing materials including PU (polyurethane), PA (nylon), and PE (polyethylene) hoses, provided the tube OD matches the fitting size. Avoid using with soft silicone tubing, which may not seal reliably in a push-in collet.

How do I install a bulkhead fitting through a panel?

Drill a hole in the panel sized to the fitting's body diameter. Insert the fitting through the hole from one side, then thread the locknut onto the fitting body from the opposite side and tighten to secure. Push your air tube firmly into the collet until it clicks into place. To release the tube, press the collet ring inward and pull the tube out simultaneously.

Which variant should I choose — PMF4, PMF6, PMF8, PMF10, or PMF12?

Choose based on your air hose outer diameter: PMF4 for 4mm tubing, PMF6 for 6mm, PMF8 for 8mm, PMF10 for 10mm, and PMF12 for 12mm. The suffix number (e.g., -01, -02, -03, -04) typically indicates the thread size on the panel-mount side — select the one that matches your panel port or mating fitting thread.
