Spears PVC & CPVC Expansion Joint

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. Available for CPVC 1/2" through 12" and PVC 1/2" through 14" IPS piping systems in 6" or 12" maximum travel lengths. Custom produced for virtually any pipe diameter.

PVC & CPVC Elastomer Expansion Joints

Elastomer Expansion Joints allow for expansion, contraction, laterals and angular movement in piping systems. Ideal for use on pumps, chillers, cooling towers, etc., to absorb pipe movement and stress, compensate for minor misalignment and off set, aid in system noise reduction and vibration dampening, and to help protect against start-up surge forces. Features reinforced Double-Arched tube design in chemically resistant Neoprene or optional EPDM elastomers. Produced in IPS sizes 3/4" through 3" with PVC or CPVC Union end connections in Socket or Spears® Patented Special Reinforced (SR) Female Plastic Th reads for convenient, reliable installations.

SPEARS PVC & CPVC Tank Adapter

• Heavy-Duty: Designed for easy adaptation and a free flow of liquids for tank or drum drainage or filling, or as outlets for distribution into a piping system, these Spears molded tank adapters withstand many times the most extreme service requirements.

• Assembly to a tank is simple: cut a hole in the tank wasll (using a hole saw) to the the dimension for your fitting size. Remove the lock nut from the fitting, leaving the EPDM gasket on the body. Insert the body through the hold in the tank from the inside, trapping the washer between the tank wall and the shoulder of the tank adapter. Screw the lock nut back onto the body for a tight, leak-free installation.
