2 Pack Female Straight Push to Connect Fitting, 4mm Tube OD x 1/8 Inch BSP Thread for Pneumatic Systems and Water Lines, Quick Air Hose Adapter PCF8-02

[Operating Specifications] Pressure range: 0 ~ 1 MPa, do not exceed 1 MPa; Temperature range: 0-60°C | 32 ~ 140 °F. Can be screwed directly into male threaded ports (e.g., solenoid valves, regulators, manifold blocks) without changing flow direction. [Leak-Proof Seal] The parallel thread is precisely machined to engage standard male threaded fittings. The metal-to-metal seal withstands vibration and pressure fluctuations up to 145 psi, suitable for air compressors, valves, and cylinders. [Flexible Adaptation] Available in straight female push-in connectors: 4mm x 1/8 inch, 6mm x 1/8 inch, 6mm x 1/4 inch, 8mm x 1/4 inch, and 8mm x 1/2 inch, covering the most common tube outer diameters of 4mm, 6mm, and 8mm. Connects pneumatic tubing to various threaded ports without needing separate adapters. [Material] Made of corrosion-resistant brass with nickel plating, resistant to oil, moisture, and temperature fluctuations. Engineering-grade nylon collet securely holds PU/PA/PE tubing without cutting or deforming it. [Efficient & Time-Saving] Simply push the tube in to form an instant airtight seal; pull the release ring backward to disconnect. No tools, PTFE tape, or heating required. Reduces assembly time by over 70% compared to traditional barbed or compression fittings.
