At a Glance: Push-in tee for 4mm pneumatic hose with 1/4" M BSP threaded connection
Build a neat branch line without a mess of adapters using the AirCraft SPB04-02 PU Hose Fitting Tee 4mm x 1/4" Male BSP. This compact tee connects 4mm PU pneumatic
hose via push-in ports across the tee, while the 1/4" BSP male thread lets you connect directly into valves, manifolds, regulators, FRL units, gauges or other BSP
female ports. It’s a smart solution for tidy control circuits and small pneumatic layouts where you need a 4mm hose run plus a reliable threaded take-off point.
Standout feauture or series/quality/range Push-in speed with a larger 1/4" BSP threaded outlet
Perfect when your hose is 4mm but the equipment port is 1/4" BSP—this tee bridges the two cleanly and keeps installations compact.
Extra Information
Designed for 4mm PU pneumatic hose on the push-in ports—cut hose ends square for best sealing.
The threaded port is 1/4" Male BSP (not NPT) — confirm thread type on your mating component.
To remove hose, press the collet in and pull the hose out gently; avoid yanking to prevent damage.
Pro Tip
If your system sees vibration, leave a small service loop in the 4mm hose run to reduce strain on the fitting and help prevent leaks over time.
