Quick coupling socket D10 – M12×1

The D10 – M12×1 quick coupling socket is a connection part where the quick-coupling side works in the D10 standard (socket), while the other side has an M12×1 thread. This type of part is used in systems where accessories need to be connected and disconnected quickly without screwing threads on and off every time, while maintaining repeatable sealing performance.

MPN / reference: 13431
Type: D10 quick coupling socket
Thread: M12×1

Application according to description: Home series (including 1050 P / 1050 TS / 1050 TST).

APPLICATION

The socket is used in typical service and assembly work:

• replacing a worn quick coupling socket in Home-series accessories,
• restoring the D10 standard during repair of a gun / hose / adapter (depending on the mounting point),
• eliminating leaks at the coupling caused by wear of the working parts,
• converting the connection to M12×1 where this is specified for the given assembly.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Replacement of the socket is justified when you notice:

• leakage at the quick coupling despite correct insertion of the plug,
• a “loose” connection (the plug has play, no secure retention),
• binding during connecting/disconnecting or lack of full latch engagement,
• damaged M12×1 thread (mounting problems, starting crooked),
• visible wear marks on the socket working surfaces after disassembly.

HOW TO CHOOSE THE RIGHT PART

Choose it based on matching parameters:

• make sure you need a D10 socket (not a D10 plug),
• confirm the threaded side: M12×1,
• verify the part number: MPN 13431,
• compare with the removed part: length, socket shape, and sealing method.

With D10 quick couplings, matching the standard is critical - “similar” parts (D10/D12) are not interchangeable and can create symptoms that look like wear, even though the real issue is incorrect selection.

COMPATIBILITY

The socket should be selected by MPN 13431 and compatibility of the D10 standard and M12×1 thread with the specific accessory. The reference to the Home series (1050 P / 1050 TS / 1050 TST) indicates the application area, but safe selection is best confirmed by the removed part and the type of the mating end (D10 plug).

[faq]

How can I tell a D10 socket from a D10 plug without measuring?|A socket is the “receiving” part - the plug is inserted into it and locked by a latch. If the part in your setup has an opening and a retaining mechanism, it is usually the socket.

Can D10 be connected to D12 because it looks similar?|No. The standards differ in the geometry of the working parts. Trying to connect D10 with D12 results in play, leakage, or lack of full latch engagement.

What most often causes leaks at a quick coupling: the socket or the plug?|It depends on wear. If the plug is scratched or worn, it can also leak. In practice, both parts should be checked, but the socket is often more commonly worn due to dirt and frequent reconnecting.

Can a damaged M12×1 thread indirectly cause leakage at the quick coupling?|Yes. If the socket does not sit axially or has play on the thread, it may work at an angle and lose sealing on the quick-coupling side.

What should I check after replacing a D10 socket?|Check whether the plug goes fully in and locks clearly, whether the connection has no play, and whether after a short pressure test there is no “sweating” at the coupling. It is also worth cleaning both the plug and socket from sand/dust - this is the simplest way to extend quick-coupling life.
