Couplings
The drilling couplings distributed by PROMAFORSOVEMA are available with or without break-out flats, in bottle shape to prevent jamming during retrieval. Several types are offered: wear coupling, reducing coupling, tool-holder coupling and non-return valve coupling. Permanently in stock at our branches for immediate availability.
Available coupling types
- Wear coupling
- Reducing coupling
- Tool-holder coupling
- Non-return valve coupling
