LUBECO™ Marine


Emulsifiable Biodegradable Stern Tube Lubricants


LUBECO™ BIO Hydrol Marine is a range of high performance, biodegradable stern tube lubricants based on synthetic esters, which provide superior lubrication, improved stability and wear protection. BIO Hydrol Marine are designed to absorb sea or fresh water entering the Stern Tube to form a stable water-in-oil emulsion while retaining excellent lubricating properties. Standard water absorption level is at 20% water contamination.
