   Universal use
• Suitable for almost any pipe material
• Joins pipes of the same or dissimilar materials
• Suitable for pressure, vacuum or suction lines
• Leakproof joint, due to the pressure responsive gasket
• Quick and simple repairs to existing pipe lines
• Stab fit design - no need to disassemble, ready to install
• Pre-assembled, stab-fit design ensures simple, rapid installation • STRAUB couplings join virtually any plain end pipe or tube
including steel, stainless steel, ductile iron, HDPE, FRP, PVC,
CPVC, C900, CPP, concrete pipe, copper,and CuNi.
• Simply cut pipes to length, center coupling and tighten bolts
• Suitable for thick or thin wall pipes
• Use a torque wrench - no other special tools or welding required
• Stress-free, flexible pipe joint
• Compensates for axial movement and angular deflection • Pressure-resistant and leak-proof even with inaccurate
pipe assembly
• Dampens water-hammer, vibration and structure-borne noise
• Stab fit, no need to disassemble and never needs retightening • Low torque required
• Seal is reinforced by increasing line pressure, ensuring long life
Easy Handling
• Detachable and re-usable, maintenance free
• Eases pipe alignment problems
• Simple and quick to install, reduces installation costs • No heat or fire hazard, can be fitted in fire risk or
confined spaces without special equipment or permits • Seals on rough pipe surfaces
• No lubrication of gasket is required
• Low torque/compression ensures long service life
• Progressive sealing effect, higher pressures reinforce the seal
• Axial restraint versions available, prevents pipe pull-out • Corrosion resistant; all stainless steel construction
• Good resistance to temperature and chemicals
• Reusable
• Compact design, saves space and allows pipes to be compactly installed
• Allows the use of low profile pipe insulation
• Easy accessed in confined areas, and can be rotated for easy
access to bolts • Light weight
All STRAUB couplings require correct use of a torque wrench for safe and proper installation. STRAUB couplings must be torqued to the specified value printed on each individual coupling. Failure to do so can result in injury or death.
