PCF Push-In Female Stud Straight Fittings — Fast, Leak-Free Air Line Connections

When you're building or maintaining a pneumatic system and a leaking or mismatched fitting brings your work to a halt, you need a connector that goes in fast and stays sealed. The PCF series push-in female stud straight fittings are designed for technicians, workshop builders, and DIYers who need reliable air line connections without the hassle of compression sleeves or thread-cutting.

Each fitting features a push-in collet on one end and a female BSP threaded port on the other. Available in tube sizes from 4mm (≈5/32") to 16mm (≈5/8") and thread sizes from 1/8" to 1/2" BSP, these inline connectors let you route air line hose directly into a threaded port on a valve, manifold, or cylinder. Sold individually (1 Pcs) or in multi-packs of 2, 5, or 10 pieces.

Typical use cases include connecting polyurethane or nylon tubing to solenoid valve ports in automated machinery, routing compressed air lines to pneumatic cylinders in workshop jigs, and building modular air distribution systems where quick tube changes are needed without shutting down the entire line.

🔗 Compatibility: Fits standard PU, nylon (PA), and polyethylene (PE) pneumatic tubing. Thread standard: BSP (British Standard Pipe) parallel. Tube OD must match fitting size exactly. BSP and NPT threads are not interchangeable — contact us if your equipment uses NPT ports.

✅ Key Features of These PCF Push-In Female Stud Straight Fittings

⚡Tool-Free Tube Insertion — Push the tube in until it clicks; the internal collet grabs and seals instantly, cutting installation time on air line hose runs.
🔩Female BSP Threaded Port — The female stud end threads directly onto male BSP ports on valves, cylinders, and manifolds, creating a straight inline push fit connector without adapters.
📐Wide Size Range — Tube sizes 4mm, 6mm, 8mm, 10mm, 12mm, and 16mm paired with 1/8", 1/4", 3/8", and 1/2" BSP threads cover the most common pneumatic system configurations.
🔄Reusable & Releasable — Depress the collet ring to release the tube without tools, making these fittings reusable across multiple installations and system reconfigurations.
🛡️Corrosion-Resistant Construction — The fitting body is constructed to withstand typical workshop environments, including moisture and oil-laden compressed air lines.
📦Flexible Pack Quantities — Order 1, 2, 5, or 10 pieces per size to match your project scope, from a single repair to stocking a full pneumatic panel build.

⚠️ Size Confirmation: Always measure your tube's outer diameter (OD) and your port's thread size before ordering. BSP and NPT threads are not interchangeable. If unsure, contact us to confirm compatibility before purchase.

❓ Frequently Asked Questions

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

Match the tube OD (outer diameter) to the first number in the part code — e.g., PCF6 fits 6mm (≈15/64" OD) tubing. For the thread, measure or check your port size: 1/8" BSP is the smallest common port, 1/4" BSP is the most widely used, 3/8" and 1/2" BSP suit higher-flow applications. When in doubt, check your compressor, valve, or cylinder body markings.

Quick reference: 4mm ≈ 5/32" | 6mm ≈ 15/64" | 8mm ≈ 5/16" | 10mm ≈ 25/64" | 12mm ≈ 15/32" | 16mm ≈ 5/8"

What working pressure can these fittings handle?

Push-in pneumatic fittings of this type are generally rated for working pressures up to 150 PSI (≈10 bar) at typical shop-air temperatures. Always verify the rated pressure for your specific application before use, particularly in high-cycle or safety-critical systems.

Can these fittings be used outdoors or in humid environments?

These fittings are typically constructed with corrosion-resistant materials suitable for standard workshop and light industrial environments, including exposure to moisture and oil-laden air. For prolonged outdoor exposure or washdown environments, contact us to confirm the specific material and finish before ordering.

What thread standard do these fittings use — BSP or NPT?

The thread sizes listed (1/8", 1/4", 3/8", 1/2") follow BSP (British Standard Pipe) parallel thread, which is the standard used in most pneumatic equipment worldwide. BSP and NPT threads are not interchangeable — if your equipment uses NPT ports, please contact us to confirm compatibility before purchasing.

Do I need any tools or sealant to install these fittings?

The push-in end is completely tool-free — simply insert the tube until it clicks and seats securely. For the threaded end, use a wrench to tighten into the port. PTFE thread tape is generally recommended on the male thread of the mating port to ensure a leak-free seal, especially on parallel BSP threads.

What type of tubing is compatible with these push-in fittings?

These fittings are compatible with standard pneumatic tubing including polyurethane (PU), nylon (PA), and polyethylene (PE) tubing with the matching outer diameter. The tube OD must match the fitting size exactly (e.g., 6mm OD tube for PCF6 fittings) for a secure, leak-free connection. Semi-rigid tubing generally provides the best collet grip.

How do I release the tube from a push-in fitting?

To release the tube, depressurize the line first, then push the collet ring (the outer ring at the tube entry) inward while simultaneously pulling the tube out. Do not force the tube out without pressing the collet — this can damage the internal grab ring and compromise the fitting's ability to seal on reinstallation.
