Straub Pipe Joint - Metal Grip


Axial-Restraint Pipe Coupling
The STRAUB-METAL-GRIP couplings join plain end pipes with axial restraint. STRAUB-METAL-GRIP provides pull out resistance in excess of the coupling's rated working pressure. Whether for pressure or suction lines, thick or thin wall pipe, the STRAUB-GRIP-L coupling is installed quickly, safely and economically. Due to the unique design of the teeth, as internal pressure increases, the anchoring effect is progressively increased. The engagement of the teeth into the pipe's outside surfaces provides for electrical conductivity across the pipe joint.
