Straub® Mechanical Couplings

Straub^® Couplings can be used to join almost any material including PVC, steel, ductile iron and concrete.

Increasing internal pressure increases the contact pressure of the sealing lip.

Straub^® Couplings are easy on pipes. As the pressure increases, so does the gripping effect.

Requires low storage space:

• Good accessibility
• Locking part can be rotated into the optimum fitting position – access only necessary from one side
• Close pipe arrangement possible, providing space for other components
• Small space required for later installation

• Installation without special tools
• No work required on pipe ends
• Removable and reusable
• Short installation time and minimum downtime
• High assembly tolerances

• Connects the broadest variety of pipe materials; also ideal for CuNiFe
• Connects different diameters
• Can be used for pressure, drainage and suction pipes

• No risk of fire or explosion during installation
• No costs for safety measures
• Quadruple safety factor
• Straub^® has all IACS approvals
• Flexible design absorbs over-stressing

• Plenty of rubber to absorb vibrations/oscillations
• Reduces pressure blows
• Reduces fatigue failures
• Noise reduction increases passenger comfort

• Increases the life of fittings and systems
• Compensates for axial displacement and misalignment
• Coupling and compensator in one

• Corrosion resistant
• Strong resistance to heat and chemicals
• Low torque guarantees long life
