Unique-Bargains MPCF4-02 4mm OD x 1/4 NPT Female Straight pneumatic accessory
Push-to-connect fitting joins 4 mm tube to 1/4 NPT female thread, rated to 1.5 MPa and 60 °C
- Push-to-connect design speeds up tube installation
- 4 mm tube OD fits 5/32 inch tubing
- 1/4 NPT female thread connects to standard ports
- Rated for 0–9 MPa operating pressure
- Operates reliably from 0 to 60 °C
4mm OD push-to-connect fitting
This push-to-connect fitting accepts 4mm outer-diameter polyurethane or nylon tubing on one end and a 1/4 NPT female thread on the other. The compact straight body measures 26mm by 17mm and weighs little thanks to its plastic-and-metal construction. It is suited for pneumatic lines in workshops, light automation rigs or portable tool setups where quick, tool-free tube changes are valued.
0-9 MPa pressure and 0-60 °C range
Rated for operating pressures from zero up to 9 MPa with a guaranteed pressure resistance of 1.5 MPa, the fitting stays sealed across a temperature span of 0 to 60 degrees Celsius. The elliptical release ring lets operators disconnect tubing by hand without special tools, while the hexagonal wrench flats allow secure thread tightening. Directional adjustment remains possible after installation, simplifying routing in tight spaces.
Replaces threaded compression joints
This connector replaces traditional compression or barbed fittings that require spanners and sealant tape for every tube change. The upgrade is worthwhile when maintenance cycles demand frequent line reconfiguration or when vibration calls for a lightweight, corrosion-resistant joint that resists cracking. Installers who prefer permanent sweat or flare connections, or who need larger bore sizes, should look elsewhere.

Questions about this item
Should I pick the 4 mm OD or 5/32 inch tube size for my line?
They are the same size; 4 mm OD equals 5/32 inch, so either marking fits the identical tubing.
What does the 0–9 MPa operating pressure mean once the fitting is installed?
The fitting handles up to 9 MPa in normal use and is tested to resist 1.5 MPa without failure.
How does the 1/4 NPT female thread limit what I can connect?
It accepts a 1/4 NPT male thread, sealing with taper engagement and thread sealant.
