M20x1.5 thread – characteristics and application

The M20x1.5 thread is a metric fine thread characterized by an outer diameter of 20 mm and a pitch of 1.5 mm. It is one of the popular threads used in power hydraulics, pneumatics, and machine construction where precision and connection tightness are required.

Features of the M20x1.5 thread:

This thread stands out due to its fine pitch, meaning the threads are more closely spaced. Thanks to this, connections with the M20x1.5 thread are more resistant to vibrations and provide a better seal than standard threads with a larger pitch. In power hydraulics, this type of thread is often found in components where compact design and high pressure resistance are important.

Application of the M20x1.5 thread

M20x1.5 threads are found in:

• hydraulic hose ends and metric fittings (e.g., DKOL, DKOS, CEL, CES),

• reducing adapters and differential sleeves,

• couplings and nuts used in pressure lines,

• cylinder heads and valve body components.

In practice, the M20x1.5 thread is found both as an external thread (male), e.g., on hose ends, and as an internal thread (female) – in fittings and sleeves.

Typical measurement values

According to the HYDRON thread identification table:

• outer diameter: 19.6 – 19.9 mm,

• inner diameter: 18.2 – 18.6 mm,

• pitch: 1.5 mm.

Why use the M20x1.5 thread?

Due to its precise fit and high tightness, the M20x1.5 thread is ideal for applications in high-pressure systems where connection safety and durability are essential. It works perfectly in components available in the store Hydron – from hydraulic connectors to service and reducing elements.
