Pneumatic Push-In Straight Fitting — Reliable Male PC Connector for Air Lines

Leaking air connections and fittings that take minutes to thread in slow down every pneumatic setup — whether you're running a workshop compressor, an automation panel, or a DIY spray system. These pneumatic push-in straight fittings are designed for technicians, machinists, and DIYers who need a fast, secure, tool-free connection between their air hose and equipment ports.

Each fitting is a single PC-type male straight connector with a brass body and collet-style push-in mechanism. The male thread end is available in M5, 1/8" (≈3.2mm), 1/4" (≈6.4mm), 3/8" (≈9.5mm), and 1/2" (≈12.7mm) to match standard pneumatic ports. The push-in tube end accepts hose outer diameters of 4mm (≈5/32"), 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), and 12mm (≈1/2"). Available in packs of 1, 2, 5, or 10 pieces.

Typical applications include connecting air hoses to solenoid valves, cylinders, and manifolds in push-to-connect air hose fitting setups; building compact pneumatic control panels where inline routing is needed; and replacing worn fittings on compressor lines in automotive shops and fabrication environments where a straight pneumatic tube fitting keeps runs clean and organized.

🔵 Compatibility: Fits standard polyurethane (PU), nylon (PA), and polyethylene (PE) pneumatic tubing. Thread sizes cover M5, 1/8", 1/4", 3/8", and 1/2" ports. Verify your tube OD and port thread standard before ordering.

⚠️ Size Note: The size format shown in variants is Thread Size – Tube OD (e.g., "1/4\"–6mm" means 1/4\" male thread × 6mm tube). Please confirm both dimensions before purchasing.

✅ Key Features of These Pneumatic Push-In Straight Fittings

⚡Tool-Free Push-To-Connect — The collet-style gripping mechanism locks onto the tube instantly when pushed in; no wrenches or clamps needed for the tube side, saving time on every push-to-connect air hose fitting installation.
🔩Brass Body Construction — The fitting body is typically machined brass, offering solid corrosion resistance and durability under repeated pressurization cycles in compressed air systems.
📐Wide Size Matrix — Thread sizes from M5 to 1/2" paired with tube ODs from 4mm to 12mm give you a male push-in air fitting for nearly every standard pneumatic port and hose combination.
🔄Straight Inline Routing — The PC straight design keeps your air line running in a direct path from port to hose, reducing bends and pressure drop compared to elbow fittings in tight panel layouts.
🛡️Leak-Resistant Seal — The male thread is designed to seat with PTFE tape for a reliable, leak-free connection; the push-in collet maintains a consistent grip on the tube OD under working pressure.
📦Flexible Pack Quantities — Order 1, 2, 5, or 10 pieces per size so you can stock exactly what your project needs — from a single repair to a full panel build with multiple PC pneumatic connectors.

❓ Frequently Asked Questions

How do I choose the right size push-in fitting for my air line?

You need to match two dimensions: the male thread size (e.g., 1/8" or 1/4") to your equipment port, and the tube OD (e.g., 6mm or 8mm) to your air hose outer diameter. Measure your hose OD with calipers before ordering. Common pairings are 1/4" thread × 6mm tube and 3/8" thread × 8mm tube. The variant label format is Thread – Tube OD.

What tube sizes do these fittings support?

These PC straight fittings are available for tube outer diameters of 4mm (≈5/32"), 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), and 12mm (≈1/2"). Select the size that matches your air hose OD — using the wrong tube OD will result in leaks or the tube not seating properly.

Are these fittings rated for high-pressure pneumatic systems?

PC-type push-in fittings are generally rated for working pressures up to approximately 150 PSI (≈10 bar) in standard compressed air applications. Always verify the pressure rating against your system specifications before installation, especially in industrial or safety-critical environments.

Can I use these fittings outdoors or in humid environments?

The brass body provides good corrosion resistance for indoor and moderately humid environments. For prolonged outdoor or high-moisture exposure, applying PTFE thread sealant tape is recommended to maintain a leak-free seal. In most cases, these fittings are not intended for submerged or saltwater applications.

Are these BSP or NPT thread fittings?

The metric M5 size uses metric threads. Fractional sizes (1/8", 1/4", 3/8", 1/2") are typically BSP (BSPP) parallel threads, which are standard in most pneumatic equipment. If your system uses NPT tapered threads, please contact us to confirm compatibility before ordering, as BSP and NPT are not interchangeable.

How do I install and remove the tube from a push-in fitting?

To install: Cut the tube end cleanly and squarely (a tube cutter gives the best result), then push it firmly into the fitting until it seats — the collet grips automatically. To remove: Press the release collar inward while pulling the tube out. No tools are needed for tube connection or disconnection.

What is the difference between PC and PL pneumatic fittings?

PC fittings are straight (inline) connectors — the tube exits in the same direction as the thread axis, ideal when your air line runs parallel to the port. PL fittings are elbow (90°) connectors used when a right-angle turn is needed to save space or avoid obstructions. Choose PC straight when routing is direct; choose PL elbow when space is tight.
