FM/UL Approved Fire Fighting Parts with Two Grooved End Coupling
Product Description
Feature: Premium ductile iron grooved coupling
1) Material: High-strength ductile iron ASTM
2) Reduces installation costs effectively
This innovative coupling is engineered for pipelines under moderate pressure, offering controlled angular, linear, and rotational flexibility at every joint. It presents remarkable benefits of expansion, contraction, and deflection—ideal for managing uneven surfaces and accommodating movements from thermal variations, settlement, seismic impacts, or other factors.
