Male Stud Push-to-Connect Brass Fittings — One-Touch Tube Connection with Threaded Port Entry

If you've ever wrestled with compression fittings or struggled to make a leak-free connection in a tight space, you know how frustrating plumbing and pneumatic work can be. These male stud push-to-connect brass fittings are designed for DIYers, machinists, and workshop builders who need a fast, reliable tube connection without special tools. Whether you're building a compressed air line, a fluid transfer system, or a 3D printer pneumatic feed, getting the right fitting the first time saves you time and headaches.

Each fitting is machined from solid brass and features a push-in collet on one end that grips semi-rigid tubing (PU, nylon, or PE) with a tube outer diameter of 4mm, 6mm, 8mm, 10mm, or 12mm. The opposite end is a male threaded stud available in metric coarse (M3 through M16) and BSPT variants — sold in convenient packs of 2, 5, or 10 pieces so you can stock exactly what your project needs.

Typical use cases include compressed air distribution lines in home workshops, pneumatic actuator porting on CNC and automation equipment, and push-fit tube connections on 3D printer extruder assemblies (such as PC4-M6 or PC4-M10 Bowden tube fittings). The one-touch collet design makes these fittings a go-to choice for anyone building or maintaining pneumatic systems with metric or BSPT threaded ports.

🔵 Compatibility Note: Match the tube OD (e.g., 4mm, 6mm) to the PC-number prefix, and the thread size (e.g., M6, M8*1, BSPT) to your equipment port. Metric and BSPT threads are not interchangeable — confirm your port standard before ordering.

✅ Key Features of These Male Stud Push-to-Connect Brass Fittings

🔩Solid Brass Construction — Machined from brass for durability in compressed air and fluid systems, offering corrosion resistance in typical workshop and indoor environments.
⚡One-Touch Push-In Collet — Insert semi-rigid PU, nylon, or PE tubing with a single push; the stainless collet grips and seals instantly without clamps or tools — ideal for fast pneumatic line assembly.
📐Wide Size Range — Tube OD from 4mm to 12mm paired with male thread sizes from M3 to M16 (metric coarse) and BSPT variants, covering the most common push-fit tube fitting sizes used in workshops and automation.
🔄Metric & BSPT Thread Options — Available in both metric coarse (standard M-thread) and British Standard Pipe Taper (BSPT) to match a broad range of pneumatic valves, cylinders, and manifolds.
🖨️3D Printer Compatible Sizes — PC4-M6 and PC4-M10 variants are widely used as Bowden tube push-fit fittings for FDM 3D printer extruder and hotend assemblies with 4mm OD PTFE tubing.
📦Flexible Pack Quantities — Choose 2, 5, or 10 pieces per order to match your project scope, whether you need a single replacement or a full workshop stock of brass push-in fittings.

❓ Frequently Asked Questions

How do I choose the right tube size and thread size?

Match the tube OD (outer diameter) to the fitting's PC-number prefix — for example, a 6mm tube requires a PC6-Mx fitting. Then match the thread to your port: M5, M6, M8, M10, M12, M14, M16 are metric coarse threads; BSPT variants (e.g., PC4-M8*1) use British Standard Pipe Taper. When in doubt, measure your port with a thread gauge or caliper. As a general reference: 1/8 BSP ≈ M9.7, 1/4 BSP ≈ M13.2.

What is the pressure rating of these brass push-in fittings?

Brass push-to-connect fittings of this type are generally rated for working pressures up to approximately 150 PSI (≈10 bar) depending on tube size and wall thickness. Always verify the specific rating for your application — contact us if you need exact figures for a critical system.

Can these fittings be used outdoors or in wet environments?

Brass has inherent corrosion resistance and is generally suitable for damp or mildly humid indoor environments. For prolonged outdoor exposure or contact with aggressive chemicals, applying PTFE tape to the threads and using a protective enclosure is typically recommended. These fittings are not rated for saltwater immersion.

Are these fittings compatible with both metric and BSPT threads?

Yes. The range includes both metric coarse thread variants (M3 through M16) and BSPT (British Standard Pipe Taper) variants such as PC4-M8*1 and PC6-M8*1.25. Metric and BSPT threads are not interchangeable — confirm your port type before ordering. If unsure, check your equipment manual or use a thread identification gauge.

Do I need tools to connect or disconnect the tubing?

No tools are needed to insert the tube — simply push the tube straight into the fitting until it clicks and seats against the collet. To release, press the collet ring inward while pulling the tube out. A wrench is needed only to thread the male stud into the port. Apply PTFE tape to the male thread before installation for a leak-free seal.

What tube materials are compatible with these push-in fittings?

These fittings are generally compatible with semi-rigid polyurethane (PU), nylon (PA), and polyethylene (PE) tubing with the correct outer diameter. Soft silicone or very flexible tubing may not seat reliably in the collet. Always use tubing with a consistent, round OD and clean-cut ends for a leak-free connection.

Should I use PTFE tape on the male thread?

Yes — applying 2–3 wraps of PTFE (thread seal) tape to the male stud thread is generally recommended before installation to ensure a leak-free seal, especially on tapered BSPT threads. For parallel metric threads, a thread sealant compound may also be used. Do not overtighten brass threads to avoid stripping.
