Internal threaded steel couplings

Internal threaded steel couplings. A coupling is a steel hexagonal or round element threaded internally, used for joining elements with external threads. Execution : galvanized free-cutting steel.  Application: industrial hydraulics, hydraulics for vehicles and agricultural machinery. Couplings are used to connect elements with external threads. Couplings are threaded internally along their entire length; we use them in situations where we need to connect two elements with external threads without cones or with cones. Due to the fact that the coupling does not have an internal cone, it can be intended, for example, for connecting straight adapters (which have an external thread without a cone) Threaded couplings can be used interchangeably with AA fittings (nut / nut) 

Metric couplings come in two versions: 

  • with the same thread along the entire length 
  • reducing with 2 different threads  

Application of threaded steel couplings in various industries

Threaded steel couplings are valued for their durability and corrosion resistance, which makes them an ideal choice in industries such as construction, the chemical industry and energy. Thanks to precise workmanship and the use of high-quality materials, these couplings provide reliable connections even in the most demanding conditions. Their versatility makes them an indispensable element in many industrial applications where durability and safety are paramount.

Benefits of using threaded steel couplings

Threaded steel couplings offer many benefits, including ease of installation and space saving thanks to their compact design. Their replacement is quick and simple, which minimizes downtime in the event of maintenance needs. Compared to other connection solutions, these couplings provide solid and durable connections that are key to the effective operation of hydraulic systems.
