Welcome to ECT Manufacturing’s premier selection of heavy-duty hollow stem auger plugs, engineered specifically to meet the rigorous demands of modern environmental sampling and geotechnical drilling. When advancing hollow stem augers, preventing soil, grout, and unwanted formations from entering the inner diameter of your auger string is critical to maintaining sample integrity and ensuring seamless monitoring well installation.
To accommodate diverse field conditions and compliance regulations, we offer our high-quality knockout plugs in two distinct materials: traditional tapered wood and advanced High-Density Polyethylene (HDPE) plastic. Our biodegradable wood auger plugs provide an economical, easily drillable option for standard geotechnical applications, while our specialized HDPE plastic auger plugs are explicitly approved for sensitive PFAS sampling to eliminate any risk of cross-contamination during environmental water testing.
Available in an extensive range of stock sizes from 2" through 10" inner diameters, ECT Manufacturing provides the precise fit, structural reliability, and technical compliance that professional drilling contractors depend on.
