Spears® Expansion Joint offers a compact, telescoping design to prevent damage from thermal expansion and contraction in thermoplastic piping systems. Ideal for both new installs and emergency repairs, it enables rigid mounting between two fixed points and doubles as a repair coupling for quick fixes in the field.
Key Features:
- Telescoping inner pipe absorbs thermal expansion and contraction
- Compact design requires less space than traditional expansion loops
- EPDM pressure o-ring provides a secure, leak-free seal
- Also functions as a repair coupling for quick line fixes
- Solvent cement-ready ends for reliable installation
