M26x1.5 thread – characteristics and application

The M26x1.5 thread is a metric fine thread with a nominal diameter of 26 mm and a pitch of 1.5 mm. It is a precision thread used in connections requiring high tightness and stability, especially where it is necessary to limit play and ensure an accurate fit of components.

Technical characteristics of the M26x1.5 thread:

• Type: metric fine thread (designation „M”),

• External diameter: 26 mm,

• Thread pitch: 1.5 mm,

• External dimension: approx. 25.6–25.9 mm,

• Internal dimension: approx. 24.2–24.6 mm.

Application of the M26x1.5 thread

The M26x1.5 thread is widely used in power hydraulics, pneumatics, and industrial engineering, appearing in:

• hydraulic hose ends (types DKOL, DKOS, DKM, CEL, CES),

• metric fittings, adapters, and reducers,

• service connections and hydraulic block components,

• installation components where resistance to high pressure and precise thread fit are essential.

This thread is often used in systems with increased operating pressure, and its fine pitch allows for better sealing of the connection compared to standard metric threads with a larger pitch.
