Pneumatic Straight Female Stud Push-In Fitting — Reliable BSP Air Line Connection

If you've ever dealt with a leaking air line mid-project — or spent frustrating minutes wrestling with compression fittings — you know how much a dependable push-in connector matters. These pneumatic straight female stud push-in fittings are built for DIYers, workshop owners, and maintenance technicians who need fast, tool-free tube connections to BSP-threaded ports on valves, cylinders, manifolds, and air tools.

Each fitting consists of a nickel-plated brass body with a BSP female threaded stud on one end and a push-in collet on the other, accepting semi-rigid pneumatic tubing in sizes from 4mm to 16mm OD. BSP thread options range from 1/8" BSP to 1/2" BSP, covering the most common port sizes found on pneumatic equipment. Available in quantities from 1 to 100 pieces per order to suit both single-repair jobs and bulk workshop stocking.

Typical applications include connecting PU or nylon air lines to solenoid valves in automated systems, plumbing compressed air distribution manifolds in garage workshops, and routing pneumatic tubing to actuators and cylinders in light industrial or DIY pneumatic circuits — all scenarios where a straight inline push-fit connector for air line work saves time and reduces leak points.

🔗 Compatibility: Designed for semi-rigid PU, nylon (PA), and polyethylene (PE) pneumatic tubing. BSP thread — not compatible with NPT ports. Confirm your port thread standard before ordering.

✅ Key Features of These Pneumatic Push-In Fittings

⚡Tool-Free Push-In Connection — The collet-style gripping mechanism locks tubing securely in place with a simple push, making installation and reconfiguration of pneumatic air line circuits fast and straightforward.
🔩BSP Female Threaded Stud — The female BSP thread screws directly onto male BSP ports on valves, cylinders, and manifolds, providing a straight inline connection without additional adapters in most standard pneumatic setups.
🛡️Nickel-Plated Brass Body — The brass construction with nickel plating offers durability and resistance to moisture, making these fittings suitable for workshop air line installations where condensation is a factor.
📐Wide Size Range — Available in tube OD sizes from 4mm to 16mm paired with BSP thread sizes from 1/8" to 1/2", covering the most common combinations used in DIY and light industrial pneumatic hose connector applications.
🔄Releasable Collet Design — Tubing can be released by pressing the collet ring inward, allowing lines to be rerouted or replaced without cutting fittings or damaging the connector body — useful for iterative workshop builds.
📦Flexible Quantity Options — Order from 1 piece for a single repair up to 100 pieces for stocking a workshop or completing a larger pneumatic circuit installation, with per-unit cost decreasing at higher quantities.

⚠️ Note: BSP and NPT threads are not interchangeable. Always verify your equipment's port thread standard before installation. Apply appropriate thread sealant (PTFE tape for tapered BSP threads).

❓ Frequently Asked Questions

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

Match the tube OD (outer diameter) to the first number in the variant name — for example, "6mm" means the fitting accepts 6mm OD tubing. The BSP thread (e.g., 1/4 BSP) must match the female port on your valve, manifold, or cylinder. Common reference sizes: 1/8 BSP ≈ 9.7mm thread OD, 1/4 BSP ≈ 13.2mm, 3/8 BSP ≈ 16.7mm, 1/2 BSP ≈ 20.9mm.

What is the maximum working pressure for these push-in fittings?

Pneumatic push-in fittings of this type are generally rated for working pressures up to approximately 150 PSI (≈10 bar) at typical ambient temperatures. Always verify the pressure rating against your system's operating conditions before installation, particularly for safety-critical applications.

Are these fittings suitable for outdoor or corrosive environments?

These fittings are typically constructed from nickel-plated brass, which provides good resistance to moisture and mild corrosion in workshop environments. For highly corrosive settings or prolonged outdoor UV and weather exposure, additional sealing or stainless-steel alternatives are generally recommended.

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

These fittings use BSP (British Standard Pipe) threads. BSP and NPT (National Pipe Thread) threads are not interchangeable — they have different thread angles and pitches. If your equipment uses NPT threads, please confirm compatibility or contact us before ordering.

Do I need thread sealant (PTFE tape) when installing?

For BSPT (tapered) threads, applying PTFE tape is generally recommended to ensure an airtight seal. For BSPP (parallel) threads, a bonded seal or O-ring is typically used at the face of the port. Check your port type and apply the appropriate sealant to prevent air leaks at the threaded connection.

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

These fittings are designed for semi-rigid pneumatic tubing such as polyurethane (PU), nylon (PA), and polyethylene (PE) with the matching outer diameter. Soft silicone tubing or braided hose is generally not compatible with push-in collet mechanisms, as the collet teeth require a firm tube wall to grip securely.

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

To release the tube, depressurize the system first, then push the collet ring (the outer ring around the tube entry) inward toward the fitting body while simultaneously pulling the tube out. Do not force the tube out without pressing the collet — this can damage the internal gripping teeth.

Can I use these fittings for fluids or gases other than compressed air?

These fittings are primarily designed and rated for compressed air applications. They may also suit inert gases and low-pressure water in many cases, but compatibility with specific fluids or gases depends on the seal and body materials. Contact us to confirm suitability for your specific medium before use.
