What is special about polymer fittings?
They must prevent moisture paths and preserve core integrity. We control crimp force, surface finishes, and sealants, validating with mechanical and environmental tests.
Why choose JOC?
Experience and discipline—our ISO frameworks and field feedback ensure fittings that last. **Let’s co-engineer your next series—**reach out via Contact Us.
