Update, October 2026: TripleHard® is in industrial use, under a Savroc licence, on a converted open-tank line for hydraulic cylinder rods at a licensed coater, with coated rods supplied to Hydroline.

Hydraulic cylinder manufacturer Hydroline Ltd has tested TripleHard®-coated piston rods in real operating conditions, and compared to Cr(VI) the TripleHard® coating works better in their demanding applications.

Savings for business and environment

TripleHard® provides significant savings for Hydroline and their customers as well as their end users. For example the stainless steel base material can be replaced with significantly lower cost material and still the durability of the application is clearly better.

Hydroline pays particular attention to environmental considerations in their manufacturing processes. According to Hydroline, they are engaged in environmentally-friendly operations, maintaining the existing level of occupational health and safety and complying with all applicable laws, decrees and regulations. TripleHard® meets these values and enables Hydroline and its customers safe and efficient workplace.

In May 2021, after those field tests, Hydroline was ready to use TripleHard®-coated rods in its applications.
