Brass GEKA claw couplings with internal thread (instant system for water and air)
The brass GEKA-type instant claw coupling with internal thread is designed for quick, reliable, and leak-tight connection of water and compressed air transmission system components. Claw couplings have a symmetrical, trouble-free design – the connection is made by pressing two couplings with the same claw spacing (40 mm) together and performing a turn, which causes the claws to lock.
The variant with a cylindrical BSP internal thread allows the coupling to be screwed directly onto sockets and connections with an external thread (e.g., in valves, manifolds, pumps, or rigid installations). The coupling is equipped with a rubber gasket (NBR), which prevents fluid leaks or air escape.
Construction and material
- Body material: Brass, protecting the component against oxidation and corrosion, which allows for long-term operation in difficult environmental conditions.
- Claw spacing (lugs): Standardized 40 mm spacing (compatible with all GEKA series claw couplings).
- Seal: Dedicated molded gasket made of NBR rubber.
Technical parameters
- Thread type: Internal inch BSP (G)
- Claw spacing: 40 mm
- Total width: 55 mm
- Working media: Water, compressed air, light chemicals
