Spears® Expansion Joints are designed to prevent damage from linear expansion and contraction in thermoplastic piping systems. Their telescoping design allows for compact installation and secure pipe movement, making them ideal for both new installations and quick repairs in residential, commercial, and industrial irrigation systems.
Key Features:
- Telescoping inner pipe allows for controlled movement and eliminates system stress
- Compact design fits in tight spaces compared to conventional expansion loops
- Ideal for use as a repair coupling in existing systems
- EPDM pressure O-ring ensures a secure, leak-resistant connection
- Durable thermoplastic construction resists corrosion and chemical damage
Technical Specifications:
- Material: Rigid thermoplastic with EPDM pressure O-ring
- Use: For expansion control or as a repair coupling
- Installation: Solvent cement ends; collapse joint, insert, and expand halfway
- Dimensions Reference:
- G = Laying length (center line to bottom of socket/thread)
- H = Center line to face of fitting (90° elbows, tees, crosses)
- J = Center line to bottom of socket/thread (45° elbows)
- L = Overall length of fitting ± 1/16 inch
- M = Outside diameter of socket/thread hub ± 1/16 inch
- N = Socket bottom to socket bottom for couplings ± 1/16 inch
- W = Height of cap ± 1/16 inch
Installation & Application:
- Recommended Uses: Residential, commercial, and industrial piping systems
- Installation Method: Solvent weld between fixed points
- Repair Applications: Can be used by collapsing joint and expanding to fill cut section
