Description
Overview:
The Speedfit Coupling Equal Straight, Metric Size 4 mm, is a compact push-fit connector for joining two lengths of the same size tube in a straight line. Built with a durable polymer body, it uses push-fit collets and an internal O-ring to create a dependable seal without tools. This makes it a practical choice for small-bore air and water lines on site, in workshops, and within machinery enclosures. Suitable for tradespeople and DIY users, it supports quick repairs and new installs where tidy, reliable connections are required. Typical uses include small pneumatic circuits, coolant or water feeds, and general fluid transfer where compatible with the media. Sold individually for precise quantity control. Manufacturer Part Number (MPN): 625 201.
