99001123 - Tweco 1Z-L Conductive Shaft Lubricant & Anti-Seize Grease, 1 oz Bottle

High-Performance Conductive Lubrication for Industrial Grounding

The Tweco 1Z-L Shaft Lubricant is a specialized chemical formulation designed to address one of the most critical aspects of high-amperage electrical circuits: contact resistance. In industrial welding and heavy manufacturing environments, the integrity of the electrical connection—specifically in moving or rotating parts—is paramount. This 1-ounce bottle of conductive paste is engineered to reduce electrical resistance by a significant margin of 40% to 50%, ensuring that current transfer remains efficient and stable even under dynamic conditions.

This lubricant is particularly essential for the maintenance and operation of roto-ground clamps. These devices, which allow for the grounding of rotating workpieces (such as pipes or vessels on turning rolls), rely on a sliding electrical contact. Without proper lubrication, these contacts can suffer from arcing, pitting, and excessive heat generation due to friction and resistance. The Tweco 1Z-L paste acts as a conductive bridge, filling microscopic imperfections in the mating surfaces and facilitating a smooth, low-resistance path for the welding current. Its composition, a black paste with a mineral oil base, ensures it adheres well to metal surfaces without running off under moderate heat.

Beyond roto-grounds, the 1Z-L lubricant is highly effective for general mechanical connections and sliding switches within industrial equipment. By minimizing resistance, the lubricant directly contributes to energy efficiency and component longevity. High resistance in a connection creates voltage drops and generates heat (I²R losses), which can degrade the conductive materials and lead to premature failure of the equipment. Regular application of Tweco 1Z-L mitigates these risks, preserving the integrity of switches, lugs, and rotary devices. It is an indispensable consumable for maintenance, repair, and operations (MRO) professionals dealing with high-current electromechanical systems.

The product is packaged in a compact 1-ounce plastic bottle, making it easy to store in a toolbox or maintenance cart. The nozzle design allows for precise application to small contact areas without waste. Whether used during the initial assembly of grounding systems or as part of a scheduled maintenance routine, Tweco 1Z-L provides the chemical reliability needed to maintain optimal electrical performance in demanding industrial settings.
