Quick coupling socket STARLET 4 D12 - 12x1,5

In high-pressure accessories, the quick coupling is responsible not only for the convenience of connecting accessories, but above all for secure seating of the working element and maintaining the tightness of the connection during operation. The STARLET 4 socket works in the gun as a connection part that must maintain repeatable fit and resistance to operating loads.

APPLICATION

This type of socket is used in STARLET 4 guns and in service work related to high-pressure systems, where quick exchange of accessories matters without giving up connection stability. The quick coupling works at a point that is regularly mechanically loaded during connection and disconnection of the lance, nozzle, or other working elements.

In practical use and service work, a part of this type is very important for the efficiency of the entire accessory system. A worn or incorrectly selected socket may cause leaks, insecure seating of accessories, or problems with their proper insertion. In workshop and industrial systems, where accessories are frequently reconnected, the condition of the quick coupling directly affects working comfort and connection safety.

SYMPTOMS - WHEN IT IS WORTH REPLACING

• the accessory does not lock in securely or has noticeable play after mounting
• leaks or seepage under pressure appear at the connection point
• the quick coupling mechanism works with resistance or does not lock the element properly
• visible signs of wear, working damage, or damage to the thread and socket are present
• the cooperating part disconnects with difficulty or cannot be seated correctly

HOW TO CHOOSE THE CORRECT COMPONENT

When selecting a quick coupling, attention should be paid to the connection parameters and compatibility with the specific gun. In this case, the markings STARLET 4, D12, and 12x1.5 female thread are important. These are what determine whether the socket will cooperate correctly with the accessories and the gun body.

Before installation, it is worth checking:

• compatibility with the STARLET 4 gun
• diameter and connection type D12
• internal thread 12x1.5
• method of seating in the gun
• compatibility with the part removed from the system

Accurate matching is crucial, because in the case of quick couplings even a small dimensional difference may result in play, lack of sealing, or problems with proper locking of the working element.

COMPATIBILITY

Compatibility of this socket should be assessed through the specific connection standard, not only by similar appearance of the part. Fitment is determined by intended use for the STARLET 4 gun, D12 parameters, and the 12x1.5 female thread. For connection elements, visual similarity alone does not guarantee compatibility, because differences in working diameter, thread, or locking geometry may prevent correct use of the accessories.

[faq]

What is the STARLET 4 quick coupling socket used for?|It is used for quick and secure connection of working accessories to the high-pressure gun. It is responsible for stable seating of the element and maintaining the tightness of the connection.

What do the D12 and 12x1.5 female thread parameters mean?|These are key installation data needed for correct part selection. They define the connection standard and thread, so they must match the gun and the cooperating element.

How can I tell that the quick coupling socket is worn?|Most often by play in the connection, problems with locking the accessories, leaks, or difficulty connecting and disconnecting the working elements.

Can such a coupling be selected only by the fact that it fits a Starlet gun?|No. In addition to the gun type itself, the connection parameters must also be confirmed, including D12 and 12x1.5 female thread, because these determine the actual fit.

Does a leak at the gun always mean the quick coupling is damaged?|Not always, but it is one of the more common causes. It is also worth checking the condition of the cooperating element, seals, and the mounting point itself, but a worn socket very often causes connection problems.
