NIPPLE OSE M39X1.5 1-1/4LH 2204180880

The NIPPLE OSE M39X1.5 1-1/4LH, part number 2204180880, is a mechanical fitting intended for connecting compatible components in industrial equipment and systems. Its primary purpose is to provide a threaded connection between components designed with matching interfaces, supporting assembly, maintenance and replacement operations.

The product designation specifies an M39 × 1.5 metric thread and a connection identified as 1-1/4 LH. The abbreviation LH generally stands for left-hand thread, meaning that tightening takes place in the opposite direction to a standard right-hand thread. Before installation, the complete thread specifications, connection geometry and tightening direction should be checked against the manufacturer's technical documentation.
Main functions and applications
1. Connecting compatible components

The nipple fitting provides a mechanical connection between components designed for threaded assembly. Depending on the intended equipment configuration, it may serve as a connecting element between compatible pipes, fittings or other threaded components.

2. Thread compatibility and dimensions

The M39 × 1.5 specification identifies a metric thread with a nominal diameter of 39 mm and a pitch of 1.5 mm. The 1-1/4 designation refers to a nominal inch-based connection size, while LH generally identifies a left-hand thread.

These designations should not be assumed to represent interchangeable thread standards. The complete thread form, dimensions and connection type must be verified before selecting or installing the part.

3. Maintenance and replacement

The component can be used in preventive or corrective maintenance when an existing fitting needs to be replaced because of wear, damage, corrosion or the need to restore a threaded connection.

Selecting the correct replacement part helps preserve the intended equipment configuration, provided that the fitting is also suitable for the relevant operating conditions and installation requirements.

4. Connection reliability

A correctly selected and installed fitting supports a stable mechanical connection. Dimensional compatibility, correct thread direction and compliance with the manufacturer's installation procedures are important for avoiding thread damage and connection problems. Where fluid or gas sealing is required, the specified sealing method must also be followed.
Typical applications
- Industrial threaded connections.
- Replacement of compatible nipples and fittings.
