Description

M8x1 threaded coupling

The M8x1 threaded coupling is a steel hydraulic fitting with internal threads on both sides, designed to connect two elements with an M8x1 external thread. The hexagonal body facilitates installation with a wrench, and its construction from free-cutting steel protected by white passivated zinc works well in typical operating conditions for power hydraulics, agricultural machinery, industrial equipment, and technical installations.

Technical parameters

  • Product: M8x1 threaded coupling, socket
  • Connector type: internal / internal hydraulic coupling
  • Thread: M8x1
  • Thread dimension according to data sheet: 7.8-8.0 mm external / 6.9-7.2 mm internal
  • Purpose: as a connector for joining elements
  • Working pressure: 250 bar
  • Operating temperature: from -20°C to +120°C
  • Length: 22 mm
  • Hexagon: 14 mm
  • Material: free-cutting steel 11SMnPb30
  • Surface protection: white passivated zinc
  • Manufacturing standard according to data sheet: metric DIN 2353 / PN-EN ISO 8434-1
  • Alternative designation: 7M-08D

M8x1 coupling for connecting elements with external threads

The M8x1 coupling has two internal threads of the same size. It is used when two ports, adapters, fittings, or other elements with an M8x1 external thread need to be connected. This is not a reduction, as it does not change the connection size. Other products from the same group can be compared in the category metric threaded couplings.

M8x1 thread - what to check before installation

When selecting this coupling, the exact M8x1 thread must be confirmed. It should not be replaced with threads of a different pitch or diameter, as the elements will not work properly. Before installation, it is worth checking the marking of the old part, the thread size, the condition of the mating element, and the sealing method provided for a given connection.

When to use an M8x1 socket?

The M8x1 socket works well for a simple connection of two elements with external threads, when no change in diameter or transition to another standard is needed. It can be used in machine hydraulic systems, lubrication systems, auxiliary measuring lines, equipment service, and during modernization of existing threaded connections. If an element with an M8x1 external thread is needed, you can also compare metric straight fittings BB.

Working pressure 250 bar

The working pressure of the coupling is 250 bar. This parameter refers to the fitting itself, but the entire system should be evaluated according to the weakest element. The limitation may be the hose, port, adapter, seal, valve, or the element to which the coupling will be tightened. The connection should be screwed axially, on clean threads, and without transferring stresses from the hose to the fitting.

Free-cutting steel and white passivated zinc

The body is made of 11SMnPb30 free-cutting steel and protected with white passivated zinc. This is a typical design for steel hydraulic components used in standard industrial conditions. If the installation works in a humid, aggressive environment, or with frequent washing, the material selection should take into account the operating conditions of the entire connection, not just the coupling itself.

Comparison with other metric couplings

When replacing an element after disassembly, it is worth comparing the thread and pitch, as differences between sizes can be easy to overlook. Neighboring variants in this category include M27x1.5 threaded coupling and M20x1.5 threaded coupling. These are not substitutes for M8x1, but they help compare the metric coupling family and avoid mistakes during selection.

Most common mistakes when choosing an M8x1 coupling

The most common mistake is choosing parts based solely on the outside diameter without checking the thread pitch. The second problem is confusing metric fine threads with standard ones. The third mistake is using the coupling as a body connector, even though an internal/internal coupling is used to join two elements with an external thread. Before purchasing, confirm the thread, working pressure, installation location, and mating elements on both sides of the connection.

FAQ

Is the M8x1 coupling a reducer?

No. It is a straight coupling with an M8x1 internal thread on both sides.

What is the working pressure of the M8x1 threaded coupling?

The working pressure is 250 bar.

What material is the M8x1 coupling made of?

The coupling is made of 11SMnPb30 free-cutting steel and protected with white passivated zinc.

What is the length of the M8x1 socket?

The length of the socket is 22 mm.

What wrench fits this coupling?

The hexagon size is 14 mm.

Does M8x1 have other thread pitches?

In M8 metric threads, various thread pitches occur, so the exact thread designation in the installation must be confirmed before purchasing.

What to check before purchasing an M8x1 coupling?

Before purchasing, check the M8x1 thread, working pressure of 250 bar, sealing method, installation location, and mating elements on both sides of the connection.
