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.

Extra Information

Best results come from a clean, square hose cut—angled or crushed ends can cause leaks.
Insert the hose fully until it bottoms out; a partial insert may blow off under pressure.
Typical use is for compressed air and pneumatic circuits—always match fittings and hose to your system requirements.

Pro Tip

Before inserting, cut the hose square with a sharp blade and wipe off dust; then give the hose a gentle tug after insertion to confirm it’s locked.

Features

Equal joiner (straight union) Connects two hose ends in-line for simple extensions and repairs.
Push-in connection Quick installation with a secure grip on the hose—no clamps needed for typical pneumatic use.
Designed for 4mm PU hose Sized for 4mm outer diameter polyurethane pneumatic tubing.
Compact body Easy to fit into tight spaces and clean routing layouts.

Benefits

Faster hose changes: Save time during installs and maintenance—push in, lock, and go.
Cleaner, more reliable air lines: Helps keep connections snug and reduces the risk of leaks from poorly secured joints.
Less waste: Repair or extend existing hose runs instead of replacing entire lengths.

Safety

Wear eye, ear and dust protection when working around pressurised air systems and workshop tools.
Depressurise the line before installing or removing fittings to prevent hose whip or sudden air release.
Confirm full insertion and pull-test the hose connection before re-pressurising.
Do not exceed system ratings—use hose and fittings suited to your compressor and regulator settings.
