M27x1.5 Thread – characteristics and application

What is the M27x1.5 thread?

The M27x1.5 thread is a precision metric thread with an outer diameter of 27 mm and a pitch of 1.5 mm. It belongs to the group of fine-pitch threads, which means that the threads are more densely spaced than in standard metric threads with a pitch of 3.0 mm. Thanks to this, this thread ensures very good sealing and connection stability in places where high accuracy and vibration resistance are required.

Characteristics of the M27x1.5 thread

The M27x1.5 thread is characterized by high mechanical resistance and tightness, making it ideal for applications in power hydraulics and pneumatics. The 1.5 mm pitch allows for smooth and precise screwing of elements, minimizing the risk of loosening. In practice, threads with such parameters are used in places where a solid metal–metal connection is necessary, often without the need for additional seals.

Application of the M27x1.5 thread in power hydraulics

The M27x1.5 thread is used in various types of connectors, ends, and hydraulic installation components, including:

• DKOL and DKOS metric ends,

• sleeves and couplings connecting hoses,

• tee and elbow couplings,

• service connections and valves.

Its fine pitch provides a larger contact surface between the threads, which increases resistance to high operating pressure – even above 400 bar, typical for power hydraulic installations.

Where is the M27x1.5 thread used?

This type of thread is primarily used in:

• hydraulic systems of construction machinery,

• presses and industrial equipment,

• pneumatic and service installations,

• connections where resistance to vibration and micro-movements is crucial.
