Quick coupling plug D10 - 1/4" Male

The D10 - 1/4" male quick coupling plug is a connection component that inserts into a D10 socket and creates a quick accessory connection without having to screw threads together every time. On the other side, the plug has a 1/4" male thread, which makes it easier to match with adapters, nipples, and accessory parts with a 1/4" female thread.

MPN / reference: 13443
Type: D10 quick coupling plug
Thread: 1/4" male (external)

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

APPLICATION

The plug is used in typical accessory assembly and service work:

• quick swapping of accessories in the D10 system in Home-series machines,
• replacing a worn plug when the connection no longer remains leak-tight or develops play,
• matching accessories with a 1/4" female thread by screwing in the 1/4" male plug,
• building a service/test setup (tests, accessory substitution) without modifying permanent hose ends.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Replacement of the plug is recommended when the following appear:

• leakage at the quick coupling despite correct locking in the socket,
• play in the connection (the plug “moves” in the socket),
• wear or scratches on the working part of the plug,
• insertion problems (the plug does not go fully in or does not lock securely),
• damaged 1/4" male thread making installation of the mating part difficult.

HOW TO CHOOSE THE RIGHT PART

Selection should be made unambiguously:

• confirm that you need a D10 plug (not a socket),
• confirm the threaded side: 1/4" male,
• verify the part number: MPN 13443,
• compare with the removed part: profile of the D10 working section and its length,
• make sure the mating part is a D10 socket and that the threaded side uses the correct 1/4" standard.

With quick couplings, the most common mistake is mixing D10 and D12 standards - the connection may seem to fit, but it will not work leak-tight.

COMPATIBILITY

The plug should be selected by MPN 13443 and compatibility with the D10 system and the 1/4" male connection in the given accessory setup. The mention of the Home series (1050 P / 1050 TS / 1050 TST) indicates typical use, but it is best confirmed by comparison with the removed part.

[faq]

Does 1/4" male mean that the plug has an external thread?|Yes. “Male” means an external thread. The mating part on that side should have a 1/4" female thread.

What are the typical symptoms of a worn D10 plug?|Most often, play appears in the socket and a micro-leak develops under pressure. Sometimes the plug “clicks” in, but the connection is not stable and can start leaking when the hose moves.

Is replacing the plug always enough if the coupling leaks?|Not always. If the D10 socket has worn guides or a worn seal, a new plug may improve the situation only partially. In that case, the socket should also be inspected and possibly replaced.

Does this plug fit every Home-series pressure washer?|It may fit if your accessories actually use the D10 standard. The safest way is to confirm by MPN 13443 and comparison with the removed part, because accessory setups may vary.

What should I do so the D10 quick coupling does not start leaking again after a short time?|Keep the parts clean (sand damages the working surfaces), do not insert the plug at an angle, and do not pull the hose in a way that loads the coupling itself. In intensive use, it is worth checking both the plug and the socket periodically for scratches and play.
