Pack of 10 PC push-in pneumatic fittings — quick air connectors with metric male threads, designed for reliable, easy connection of air pipes. Key benefits Fast, tool-free installation: push-in design lets you connect and disconnect tubing quickly to save time during assembly and maintenance. Broad compatibility: metric male threads make these fittings compatible with common metric-port pneumatic components and air lines. Practical assortment: the set covers a range of metric sizes so you can handle multiple connection needs without ordering single parts. Durable for pneumatic use: made from PC material and intended for pneumatic applications, these fittings balance strength and lightweight handling for routine compressed-air systems. Product highlights Quantity: 10 pieces per pack. Type: Push-in / quick air connector. Thread: Metric male threads. Sizes included: M5, M6, M8, M10, M12, M14, M16, M20. Example model: PC8M12x1.75. Material: PC (for pneumatic applications). How this solves common problems Eliminates slow, threaded-only assembly by providing a secure push-fit connection for flexible air tubing. Reduces the need to stock many single-size fittings: multiple metric sizes in one pack simplify repairs and prototyping. Helps maintain clean, compact pneumatic runs where space and accessibility matter. Typical use scenarios 1. Workshop compressed-air lines — quickly route and reconfigure air supply to tools, airbrushes, or blow-off nozzles using metric-threaded ports. 2. Factory automation and machine maintenance — swap or replace connectors on pneumatic cylinders, valves, and actuators without extended downtime. 3. DIY projects and prototyping — test different tubing layouts and component combinations with easy push-in connections and a variety of metric sizes. What you get Ten PC push-in pneumatic fittings with metric male threads, covering the listed metric sizes; example model PC8M12x1.75 is included among the compatible models. Compatibility notes Designed for metric-threaded pneumatic ports and flexible air tubing. Confirm thread size (M5–M20) and tubing inner diameter compatibility before installation. Materials and intended use Constructed from PC material for use in pneumatic applications. Use these fittings for compressed-air systems where push-in convenience and metric thread compatibility are required.
