AirCraft PU Hose Fitting Equal Joiner 4mm (SPU04)
At a Glance: Push-in equal joiner for 4mm PU hose—fast, tidy line-to-line connection.
The AirCraft SPU04 PU Hose Fitting Equal Joiner 4mm is a neat little problem-solver for pneumatic setups: it joins two lengths of 4mm polyurethane (PU) hose in a straight line with a quick push-in connection. Perfect for extending a line, repairing a cut hose, or creating clean routing in compact air systems, this fitting helps keep your air lines secure and organised while reducing the chance of annoying leaks caused by loose connections.
Standout feature: Quick push-in “one-touch” union for 4mm PU hose
Push the hose in to lock it, and release it just as easily when you need to re-route or service your line—ideal for workshops, pneumatics, and air accessories where changes happen fast.
