Push-In Pneumatic Fitting

-- Steady & Reliable Manufacturer --

Introduction

Push-in pneumatic fittings — sometimes called push-to-connect or instant fittings — are one-touch connectors designed to join flexible tubing to pneumatic systems without any tools or thread sealants. The fitting body features a collet mechanism that grips the tube outer diameter the moment it is inserted, forming an immediate, reliable seal. Removal is just as simple: press the release ring and the tube slides out cleanly, making reconfiguration fast and repeatable.

At Fenglan, we produce push-in pneumatic fittings from high-quality nickel-plated brass and engineering-grade polyamide (PA), offering configurations that cover straight, elbow, tee, cross, Y-shape, and bulkhead styles. Whether you are building a compact automation cell or a large-scale pneumatic circuit, our fittings are engineered to hold pressure reliably and resist vibration over millions of cycles.

Our fittings are compatible with metric (4–16 mm OD) and imperial (1/8"–5/8" OD) tubing, and thread connections follow BSP, NPT, and metric standards so they integrate smoothly into existing installations around the world.

Applications

Push-in pneumatic fittings are found wherever fast, dependable air-line connections are needed. Common application areas include:

Industrial Automation: Robotic arms, pick-and-place systems, pneumatic actuators, and conveyor line cylinders rely on push-in fittings for quick changeovers and minimal downtime.
Packaging Machinery: High-speed packaging lines use these fittings to connect sensors, vacuum cups, and air-blow stations in tight cabinet spaces.
Medical & Life Sciences: Cleanroom-compatible PA versions are used in dental chairs, ventilators, and laboratory automation where particle contamination must be minimized.
Food & Beverage Processing: FDA-compatible seal options allow use in direct-contact and washdown environments.
Automotive Assembly: Spray painting booths, leak-test rigs, and tire-inflation stations benefit from the tool-free speed of push-in connections.
Semiconductor & Electronics: Ultra-clean environments use miniature push-in fittings for precision vacuum grippers and wafer-handling equipment.

Advantages

Tool-Free, One-Touch Connection: Insert the tube and the collet locks it instantly — no spanners, thread tape, or adhesives required. Reduces assembly time by up to 60% compared to traditional compression fittings.
Reusable & Reconfigurable: Press the release collar to remove the tube without damage. Fittings and tubing can be reused multiple times, lowering total cost of ownership.
Consistent Leak-Free Sealing: Precision-ground collet teeth and a dual-lip O-ring eliminate micro-leaks even under vibration and pressure fluctuations.
Wide Material & Size Range: Available in brass and engineered PA bodies with a full range of thread sizes and tube ODs, covering the majority of global pneumatic standards.
Corrosion Resistance: Nickel-plated brass body and 304 SS collet withstand moisture, oil mist, and mild chemical exposure found in typical factory environments.
OEM & Custom Options: Non-standard thread combinations, custom body materials (stainless steel, PVDF), special seals, and private-label packaging are all supported.

Payment & Shipping

Payment Terms: We accept T/T (wire transfer), L/C at sight, PayPal, and Western Union. A 30% deposit is required before production begins, with the remaining 70% settled before shipment. For established long-term customers, flexible credit arrangements can be discussed on a case-by-case basis.

Lead Time: Standard production lead time is 7–15 business days after deposit confirmation. For urgent orders, expedited scheduling may be available — please contact our sales team to check availability.

Shipping & Logistics: We ship worldwide via DHL, FedEx, UPS, TNT, and by sea (LCL or FCL). Incoterms supported include EXW, FOB Ningbo/Shanghai, CIF, and CFR. The most cost-effective option is selected based on order weight and destination.

Packaging: All items are individually inspected, then packed in anti-rust film and foam-lined export cartons. Custom branding, inner packaging, and labeling are available on request. Packaging fully complies with international freight standards.

Quality Assurance: Every shipment is accompanied by an inspection report and, where applicable, material certificates (e.g., RoHS, REACH). We support third-party inspection arrangements (SGS, BV, etc.) if required.

FAQ

Q: What types of tubing are compatible with push-in pneumatic fittings?
A: Our push-in fittings are designed for use with flexible tubing in PA (nylon), PU (polyurethane), PE (polyethylene), and PVC. The tube must have a smooth, round outer diameter within the specified tolerance range (typically ±0.1 mm) for a reliable seal. Rigid copper or stainless steel tubing is not compatible with standard push-in models.

Q: Can push-in fittings handle vacuum applications?
A: Yes. Standard models are rated for vacuum down to -100 kPa. This makes them suitable for vacuum grippers and suction-cup circuits. For sustained deep-vacuum duty (<-90 kPa continuous), we recommend confirming the seal grade with our engineering team.

Q: What is the minimum order quantity (MOQ)?
A: MOQ is typically 100 pieces per item for standard catalog sizes. For custom configurations or special materials, MOQ may vary — please contact us with your drawing or specification for a specific quote.

Q: Are the fittings RoHS compliant?
A: Yes, all our pneumatic fittings comply with RoHS Directive 2011/65/EU and REACH regulations. Material safety data sheets and test reports are available upon request.

Q: Can you supply fittings with custom thread types or body colors?
A: Absolutely. We support custom thread forms (BSP, NPT, metric, UNF), custom PA body colors for color-coded circuit identification, and special sealing materials such as FKM for chemical resistance. Please share your requirements and we will provide a tailored solution.
