Zero-Leak Gold port entry plugs for hydraulic applications feature a taper under the head, forming a metal-to-metal seal. In conjunction with an elastomeric backup seal, the plugs are said to outperform any old style straight thread O-ring only plug. Available in steel, stainless steel, and aluminum, they come in metric and English sizes and feature the size engraved on the head of each plug for easy identification.
