5 Pcs 6mm/8mm Push to Connect 90 Degree Elbow, Pneumatic Air Flow Control Valve Fittings for Compressor and Systems, 1/4 Inch Thread

【Universal Compatibility】Sizes: 6mm OD x 1/4 inch, 6mm OD x 1/8 inch, 8mm OD x 1/4 inch, 8mm OD x 1/8 inch. The mixed design lets you combine push‑to‑connect convenience with traditional threaded ports without extra adapters. 【Tight‑Space Adaptation】The right‑angle design redirects airflow where straight fittings cannot fit. Ideal for routing pneumatic tubing around obstacles, inside machinery enclosures, or along panels, saving valuable space while maintaining full flow. 【Precise Adjustment】Unlike standard elbows, this fitting incorporates a built‑in throttle valve. Turn the knurled knob to finely adjust cylinder speed, actuator response, or pneumatic tool performance. Use the locking ring to secure settings against vibration. 【Push‑to‑Connect】Simply insert the tube into the fitting; the collet grips firmly and the O‑ring instantly creates an airtight seal. 【Durable Material】Corrosion‑resistant brass body and threads, with engineering‑grade plastic in the push‑to‑connect mechanism. This combination withstands working pressures up to 145 psi, resists oil and moisture, and delivers long‑lasting reliable performance in workshop pneumatic systems.
