Lubricator Length

• “Consider the tool string length when sizing the lubricator length. The available length to swallow a tool string is from the top of the swab valve to the bottom of the flowtubes. This length should be the TOTAL tool length, line head to bottom nose, plus 3 extra feet.”

Stuffing Box – the Main Seal on the Wire

• Braided Line – Grease Injector

• Slick Line - Rubber elements with and without oil injection capacity. A hydraulic oil is usually used for sealing and lubrication of the wire.
