Whether you're building a workshop compressor setup, a pneumatic automation system, or a custom air-line installation, a properly rated bulkhead push-fit connector fitting gives you a clean, secure through-panel connection that holds pressure and stays put. Each fitting is a single bulkhead push-fit connector unit, available in tube sizes of 4mm (≈5/32"), 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), and 12mm (≈1/2"). The body is constructed from durable engineering-grade material (typically nickel-plated brass or reinforced polymer depending on variant), with a stainless-steel collet and an elastomeric O-ring seal. Sold in quantities of 1, 5, 10, or 20 pieces to suit single repairs or larger installations. Typical applications include mounting air lines through machine enclosure panels in industrial automation, routing airline tubing through workshop cabinet walls for organized compressor plumbing, and creating clean bulkhead pass-throughs in pneumatic control cabinets — all scenarios where a push-fit bulkhead airline fitting eliminates the need for threading or soldering. 🔵 Compatibility: Designed for standard pneumatic tubing with outer diameters of 4mm, 6mm, 8mm, 10mm, or 12mm. Suitable for polyurethane (PU), nylon (PA), and polyethylene (PE) air line tubing. Select your tube OD from the size options above. ✅ Key Features of These Pneumatic Bulkhead Push-Fit Connector Fittings 🔩Tool-Free Push-Fit Connection — The stainless-steel collet grips tubing instantly on insertion; no clamps, wrenches, or adhesives needed for a secure inline airline connection. 🛡️Leak-Resistant O-Ring Seal — An elastomeric O-ring seated inside the fitting body creates a reliable air-tight seal, reducing the risk of pressure loss in pneumatic systems. 📐Bulkhead Panel-Mount Design — The threaded body and lock nut allow the fitting to be mounted through panels or enclosure walls, keeping airline routing clean and organized. 🔄Reusable & Reconnectable — Push the collet ring to release the tube for repositioning or maintenance; the fitting retains its sealing performance across multiple connect/disconnect cycles. 📏Five Tube Sizes Available — Covers the most common pneumatic tubing ODs from 4mm to 12mm, making it straightforward to match your existing push-fit airline tubing without adapters. 🏭Broad Application Range — Suited for workshop compressor plumbing, industrial machine enclosures, pneumatic control panels, and DIY air-line installations where a through-panel bulkhead fitting is required. 📐 Technical Specifications — Pneumatic Bulkhead Push-Fit Connector Fittings Fitting Type Bulkhead Push-Fit (Inline / Straight) Tube OD Sizes 4mm (≈5/32"), 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), 12mm (≈1/2") Body Material See variant options (typically nickel-plated brass or engineering polymer) Collet Material Stainless steel (typically) Seal Type Elastomeric O-ring Working Pressure Typically up to 150 PSI (≈10 bar) — contact us to confirm Compatible Tubing PU, PA (Nylon), PE pneumatic tubing Panel Thickness Range Typically 1mm–5mm — contact us to confirm Thread Standard (Nut) See variant options or contact us to confirm Connection Style Push-fit (collet release) Pack Quantities 1 pcs / 5 pcs / 10 pcs / 20 pcs Country of Origin See variant options ❓ Frequently Asked Questions How do I choose the right tube size for my bulkhead fitting? Match the fitting size to your tubing's outer diameter (OD), not the inner diameter. Measure your existing tube OD with calipers before ordering. Available sizes and their approximate inch equivalents: 4mm (≈5/32"), 6mm (≈1/4"), 8mm (≈5/16"), 10mm (≈3/8"), 12mm (≈1/2"). When in doubt, size up — a fitting that's too small will not accept the tube. What working pressure can these fittings handle? Pneumatic push-fit bulkhead fittings of this type typically support working pressures up to 150 PSI (≈10 bar). Always verify the rated pressure for your specific application and do not exceed the system's rated limits. Contact us to confirm the pressure rating for your chosen size. Can these fittings be used outdoors or in humid environments? The body material — generally nickel-plated brass or engineering-grade polymer — offers good resistance to moisture in most workshop and light industrial environments. For prolonged outdoor exposure or high-humidity conditions, we recommend confirming the material of your specific variant and applying PTFE tape on the threaded nut for added protection. What thread standard is used on the bulkhead nut? Bulkhead push-fit fittings in this size range typically use metric or BSP (British Standard Pipe) threads on the panel-mount nut. Please see the variant options or contact us to confirm the exact thread standard for your chosen size before drilling your panel hole. What panel thickness can the bulkhead fitting accommodate? Most bulkhead push-fit fittings in this range accommodate panel thicknesses of approximately 1mm–5mm. If your panel is thicker, contact us before ordering so we can confirm compatibility or suggest an alternative. Is any sealant or tape required during installation? The push-fit collet provides a tool-free, leak-resistant seal on the tube side — no sealant needed there. For the threaded panel-mount nut, applying PTFE thread tape is generally recommended to ensure a reliable air-tight seal, especially in higher-pressure systems or where vibration is present. Can I reuse these fittings after removing the tube? Yes. Push-fit fittings are designed for repeated connect and disconnect cycles. To release the tube, press the collet ring inward while pulling the tube out. The fitting can typically be reused multiple times without loss of sealing performance, making it practical for prototyping or reconfigurable pneumatic layouts. 🛒 Select your size and quantity above, then add to cart — ships from our US warehouse.
