Nipple M12x1 - M22x1,5

The 12×1 female > 22×1.5 male nipple is a transition fitting that allows you to connect components with different thread standards: 12×1 female (internal) on one side and 22×1.5 male (external) on the other. It’s used when adapting accessories, repairing fittings, or reconfiguring connections when you need to match threads without replacing the entire component.

MPN / reference: 13363
Thread: 12×1 female → 22×1.5 male

APPLICATION

The nipple is used in typical assembly and service work:

• transitioning between 12×1 and M22×1.5 in the accessory flow path,
• matching hose ends, trigger guns, adapters, or connector components,
• repairing the system after a previous connector was damaged/worn,
• building a service/test configuration to join incompatible threads.

SYMPTOMS - WHEN IT’S WORTH REPLACING

Consider replacing the nipple when you notice:

• leaks at the threaded joint despite correct tightening,
• thread damage (stripped, worn, galled),
• cracking or deformation after overload,
• difficulty threading in straight (cross-threading tendency),
• recurring leaks after disassembly when thread wear is visible.

HOW TO CHOOSE THE RIGHT PART

Selection should be unambiguous:

• confirm thread types and direction: 12×1 female (internal) and 22×1.5 male (external),
• verify the manufacturer number: MPN 13363,
• compare with the removed part: length, shape, and sealing method,
• check the condition of mating threads-worn seats can leak even with a new nipple.

In pressure-washer accessories, similar threads can be confused (especially 22×1.5), so verifying pitch and thread type is essential.

COMPATIBILITY

Select the nipple based on MPN 13363 and compatibility of the 12×1 female and 22×1.5 male threads with the mating components. The safest confirmation is comparison with the removed part and the accessory documentation for the system where it will be used.

[faq]

What do “female” and “male” mean in the nipple description?|Female means an internal thread, and male means an external thread. Here the nipple has 12×1 female on one side and 22×1.5 male on the other.

Is 22×1.5 the same as M22×1.5?|In pressure-washer accessories, usually yes-the 22×1.5 notation typically refers to an M22 thread with 1.5 mm pitch. Still, it’s safest to confirm against the removed part because multiple M22 connector variants exist.

Why can the joint leak even with a new nipple?|Most often due to damaged threads or sealing surfaces on the mating component, contamination on the thread, or misaligned assembly.

Is this nipple used to “extend” a connection?|It can change geometry slightly, but its main role is thread conversion. If you need an extension, choose a part designed with the required length and construction.

How can I avoid thread damage during installation?|Clean the threads, start straight, and don’t use excessive force. If it doesn’t engage smoothly from the start, stop and verify fitment-forcing it usually damages the thread.
