Spears® Expansion Joints provide a reliable solution for managing thermal expansion and contraction in thermoplastic piping systems. Designed for residential, commercial, and industrial applications, these expansion joints allow for telescoping movement to absorb stress and prevent damage from temperature fluctuations. Ideal for compact installations or use as a repair coupling, they offer efficient, long-lasting performance.
Key Features:
- Telescoping design for compact installation between fixed points
- Functions as an expansion joint or repair coupling
- High-quality EPDM pressure o-ring for leak prevention
- Rigid mounting capability eliminates need for expansion loops
- Allows solvent cement installation for permanent connection
Construction & Durability:
- Thermoplastic materials resistant to corrosion and chemical exposure
- EPDM pressure o-ring provides durable, leak-free performance
- Precision-manufactured for dimensional accuracy
Performance & Functionality:
- Allows linear expansion and contraction movement within piping systems
- Suitable for use in both new installations and repair applications
- Prevents system damage from thermal stress and pipe deformation
