QT-DS-MF-02 Male 1/4 / Female 1/4
A brass threaded fitting for compatible pneumatic connections. Match each mating thread, actual thread profile, pitch, sealing arrangement and available clearance before ordering. Nominal inch designations are pipe-thread names, not measured opening diameters.
One complete fitting
Each base sales unit contains 1 complete adapter of the selected model. Pipes, other fittings, thread-sealing tape, tools and boxes are excluded.
The selected-SKU photograph is retained at its original proportions; no rear view or hidden structure has been generated.

The unchanged original SKU card retains its approximate supplier labels and separate dimension axes. It is a photographic reference, not a controlled CAD drawing. Opening-size and male-size labels must not be treated as certified standard male thread outside diameters. Overall and component axial labels are independent source references; do not add them to derive a replacement total.
Match, seal and check.
Isolate and fully depressurize the system before installation or removal. Inspect mating threads and remove debris. Use a sealing method compatible with the actual thread and seat design; follow equipment instructions. Turn the fitting at its metal hex or wrench flats with a suitable tool. Avoid cross-threading and do not force the connection. Restore air gradually and inspect all joints for leakage before use. Fully depressurize before adjustment.
