TRANZ® Hypalube A425
Ultra-High Performance Seals Lubricant - Engineering Applications
Specifically Developed for Lubrication of Pneumatic Cylinder seals
TRANZ Lubricants Australia, a division of Field Performance, has had a long and successful history in the development of outstandingly superior lubricants in many highly specialized and extreme performance applications, oftentimes, where no other product has been able to serve. No product characterizes Field Performance capacity more than our TRANZ Hypalube A425 lubricant, developed in collaboration with aluminium smelting industry technicians.
TRANZ A425 evolved in 1992 from our continuous product development over a decade in which Australia's numerous smelter groups established and expanded their pot lines with ever higher performance envelopes set for the pneumatic cylinders operating their integrated feeders. Made for cell ‘lifetime’ lubrication of the thousands of both rubber and composite lip and rod seals in the pneumatic cylinders of integrated feeders working at extremely high temperatures on electrolytic cells, since 1991 TRANZ A425 has shown outstanding service in some of the World's most extreme smelting environments, TRANZ A425 has a proven service cell lifetime of a minimum 5, and up to 7 plus years crustbreaker pneumatic cylinder seals service life.
TRANZ A425 has a high electrical insulation value, a major advantage in the highly charged environment of electrolytic cells, in contrast with the undesirable conductance of competitive products based on carbon black, graphitic carbon and metal salts like molybdenum disulphide.
Exceptionally rigorous independent laboratory testing in Melbourne Victoria commissioned by one of Australia's largest smelters, together with unceasing side-by-side operational comparison, has service-proven TRANZ A425 as the absolute World's Best.

PNEUMATICS
Rock-solid reliability in the most extreme smelting environments in the world, establishes TRANZ A425 as State of the Art, especially the completely proven 7 plus years service life, which represents a ‘lifetime’ of the cylinder seals, in crust-breakers exposed to the extremity of conditions under which no other compound from the World's best, has been able to serve. Whether pneumatic cylinder seals are elastomer, thermosetting plastic, ceramic, or combinations of these, TRANZ Hypalube A425 lubricant compound is ready for service, from environmental temperatures from -40°C, up through every ambient and on, to continuous temperatures as high as 215°C with short term (10 to12 Hrs.) overload capacity of 235°C
CYLINDER SEALS
The data listed here refers to the lubrication of piston and rod seals in high pressure pneumatic equipment, but this capability could extend to any plant in which seals play a vital part.
The single most important aspect of products for service in this business area, is the absolute necessity of the lubricant having proven zero effect on the dimensional stability, tensiles and modulus, of the full range of organic and inorganic elastomers and composites used in seals construction, plus zero reactivity with all the associated materials including metals, ceramics and plastics that are found in modern seal assemblies. Reliable performance under these conditions cannot ever be theorized. It requires lengthy and detailed stability study plus extensive service exposure. In this respect TRANZ offers compounds that have withstood the most critical and far ranging contact stability testing, trials and full service since 1988.
Selection Criteria:
The primary confirmation criteria for selecting the TRANZ A425 product is the full operating temperature envelope. When assessing service criteria, it is imperative to know with accuracy both the base and the peak temperature to which the seals will ever be exposed as well as the normal service range, since these figures alone confirm the suitability of A425.
