Malleable Iron 529 valve socket, called Extension Pieces M/F. valve socket is one kind of socket with one end of external thread and the other end is internal thread. Socket M/F is used to connect two pipes or fittings which have the same diameter and one is internal thread and the other one is external thread.

Classification of threads by shape：
Threads of the valve socket can be classified based on their shape, two common classifications are:
1. Straight threads: These threads have a constant diameter along their length. There are two main types:
Parallel Threads: Also known as cylindrical threads, they maintain a constant diameter throughout their length. They are commonly found in applications such as bolts, screws and nuts where the threads run straight along the axis.
2. Tapered threads: These threads vary in diameter along their length and usually form a point. The angle of taper can vary. This type includes:
Pipe Threads (Tapered): Such as NPT (National Pipe Taper), these threads are designed to form a tight seal when tightened and are commonly used on pipes and fittings.
Tapered threads for sealing (e.g. Whitworth standard): For sealing, these threads create a tighter seal due to the tapered design.
These classifications determine how threads are used, whether for assembly, sealing, or specific applications such as pipes or fasteners.
