FIBERGLASS DOUBLE EXPANSION JOINT, NO O-RINGS (ID)
The Fiberglass Double Expansion Joint (ID) is a high-performance, precision-engineered component designed to provide superior flexibility and expansion control in above-ground fiberglass conduit systems. This fitting, commonly known as a back-to-back expansion joint, is essential for long conduit runs exposed to frequent temperature variations. It helps maintain the structural integrity and durability of fiberglass conduit installations by compensating for the natural expansion and contraction caused by fluctuating environmental temperatures. By allowing these movements, it prevents stress and damage, ensuring the conduit remains properly aligned and intact over time. This joint is particularly valuable for applications requiring seamless management of thermal changes over large distances, enhancing the reliability and longevity of the system in demanding conditions.
Applications:
- Above-Ground Fiberglass Conduit Installations: Ideal for conduit systems exposed to environmental temperature changes.
- Extended Fiberglass Conduit Runs: Perfect for long, continuous conduit spans where expansion control is crucial for structural integrity.
- Utility and Infrastructure Projects: Widely used in industrial, utility, and infrastructure settings to protect against temperature-induced damage.
Key Features:
- Double Expansion Capability: Accommodates greater movement than single expansion joints, ideal for complex or extensive fiberglass conduit runs.
- ID-Sized Fiberglass Conduit Compatibility: Designed for easy integration with ID-sized fiberglass conduits, ensuring a snug and secure fit.
- Yellow Line Indicator: Features a yellow line on the nipple end for precise installation and alignment, reducing setup errors.
Benefits:
- Reliable Expansion Control: Prevents damage to fiberglass conduit systems by allowing controlled expansion and contraction.
- Durable and Long-Lasting: Built to withstand temperature variations and environmental exposure, ensuring long-term performance.
- Simplified Installation: The yellow line indicator assists with proper orientation and setup.
- Adaptable Solution: Suitable for above-ground fiberglass conduit installations that require consistent performance over long distances.
