Linear expansion and contraction from temperature fluctuations can be a major problem in thermoplastic piping systems. Forces left uncontrolled can literally tear systems apart. Spears® Expansion Joint allows a telescoping movement of an inner pipe within a firmly mounted outer tube to eliminate such damage.
Telescoping design allows more compact installation than possible with conventional expansion loops and permits rigid mounting between two fixed points. Excellent For Use as a Repair Coupling - Simply cut damaged pipe section from line, collapse expansion joint, solvent cement ends and expand halfway to install.
