Frequently Asked Questions
What is the difference between Grip-L and standard Straub couplings?
The Grip-L type features a longer rubber sleeve that provides additional grip and sealing on the pipe, making it suitable for higher pressure applications and pipes with minor surface irregularities.
Can this coupling be used for seawater or fresh water?
The NBR sleeve is designed for oil and organic gas. For water applications, a different rubber compound (e.g., EPDM) is recommended. Please check compatibility with your medium.
What is the maximum working temperature for the NBR sleeve?
NBR typically operates between -20°C and +100°C. For extreme temperatures, consult the manufacturer's guidelines.
Is this coupling suitable for permanent installation or only emergency repairs?
It is suitable for both permanent and temporary connections. The robust design ensures reliable long-term service in ship piping systems.
