Core Ejection Piston

🔧 Core Ejection Piston – Reliable Core Discharge Solution for Wireline Drilling

Precision-Engineered Core Ejection Piston for Smooth and Efficient Core Removal
Ideal for Wireline Core Drilling, Mineral Exploration, and Geotechnical Sampling


✅ Product Overview:

The Core Ejection Piston is an essential component of the inner tube assembly in wireline core drilling systems, designed to push or eject the recovered core sample from the inner tube once it reaches the surface. It enhances core handling efficiency and ensures clean, damage-free core removal, improving overall core sample quality and workflow during mineral exploration or geotechnical drilling.

This rugged tool is built to operate reliably under harsh field conditions and integrates seamlessly with NQ, HQ, PQ, and other wireline core barrel systems.
