Opti-Lube Soda Block Grease - 1 Carton of 12 Blocks - Approx. 46 lbs.

Soda Block Grease

Opti-Lube Soda Block Grease is a very firm, soda-based lubricant used in steam railroad applications that specify hard block grease. It contains wear-reducing additives and can be shaped or pressed into grease sticks for systems designed to accept this format.

Where this formula fits

The starting point for steam railroad equipment that calls for soda-based hard block grease. The very firm block format can be shaped or pressed into grease sticks where the lubrication system is designed to use them.

Before choosing: Match the locomotive or equipment specification, including consistency and how the grease is fed to the lubrication point. Keep the standard Soda and Soda with Moly formulas distinct.

What makes it different

• Formula: Soda in a hard block format for systems designed to use solid grease.
• Consistency: Published cone penetration 18–22; worked, 60 strokes at 77°F (ASTM D217). This records the stated test condition rather than a general-purpose cartridge grease grade.
• Supply options: One approximately 4 lb block or a carton of 12 blocks, approximately 46 lb per carton.

Choose your size

SINGLE BLOCK: One block, approximately 4 lb.
CASE OF 12 BLOCKS: One carton containing 12 blocks, approximately 46 lb total. Weights are approximate.

Published specifications

Reading the test values: Dropping point is not a maximum operating temperature. Worked and unworked penetration tests use different sample conditions; do not use them as a single hardness ranking across all formulas.

Before putting it into service

Confirm the grease specification for the exact lubrication point, the required block consistency and grease-feed fit. Follow the equipment manufacturer’s procedure for changing products, replenishing grease and inspecting the component.
