What is the typical lead time for bulk orders?
Standard lead time is 3–5 business days for in-stock units. For orders >20 pcs, lead time is 10–14 days — we confirm availability and timeline upon quote request.
How is quality assured before shipment?
Each unit undergoes dimensional inspection (CMM), surface finish verification, and functional pressure testing. Full traceability and test reports available on request.
Can I use this as a direct replacement for an Epiroc-branded part?
Yes. Following the Epiroc rebrand, COP 1838HD+ parts remain mechanically and dimensionally identical — this part is certified compatible with both Atlas Copco and Epiroc service documentation.
Do you offer technical support for installation or troubleshooting?
Yes. Our application engineers provide free pre-installation guidance, torque specs, and flushing system diagnostics — contact us with your rig configuration and operational challenges.
