FM/UL Approved Fire Fighting Parts - Two Grooved End Coupling
Product Description
Feature: High-quality ductile iron grooved coupling
1) Material: Superior ductile iron ASTM
2) Significantly reduces installation costs
This coupling is ingeniously crafted to bear moderate pipe pressure, allowing for controlled angular, linear, and rotational movements at each joint. It offers exceptional advantages of expansion, contraction, and deflection, making it ideal for accommodating uneven laying surfaces and mitigating movement from thermal changes, settling, seismic activity, or other dynamic forces.
