|
STOPS Leaks
Liquid Intelligence 235 creates a permanent seal. The ester and phenol chemical combination swells, softens and rejuvenates the physical properties of dried and hardened seals.

STOPS Breakdowns and Premature Aging
Liquid Intelligence 235 swells, softens and rejuvenates wiper seals. Wipers / scrapers seals are the hydraulic systems first line of defence in protecting a system and keeping it free from dirt, mud, water, and other contaminants. Contamination particles in the hydraulic system are the most common reason for breakdowns and short service life of seals.
Premature hydraulic system failure is often due to particulate and moisture contamination via worn cylinder seals.
With their constant exposure to dirt, particulates, and the elements, the hydraulic cylinder seals used on heavy equipment are susceptible to frequent wear. Dirt and other contaminants can adhere to exposed cylinder rods, making the surface uneven and abrasive. Over time, the dirt continues to build up, eventually wearing down the cylinder seals and allowing contaminants to enter the hydraulic system. Once in the system, these particulates act as a lapping compound, which can wear down valves and pumps, and lead to premature system failure.
Liquid Intelligence 235 not only stops leaks but works to prevent particulate and moisture contamination… an excellent form of preventative maintenance

STOPS Costly Repairs
We recommend using this product before attempting costly repairs
Liquid Intelligence 235 can and should be used as a first step option to avoid costly repairs. Hydraulic system repairs can range in price upwards from $300 to $3000 and even higher.
This product is guaranteed where the leak is not copious and so it is worth a shot… and of course please talk to our technical support if you would like to discuss your particular situation.

Will Work For You If You Have The Following Kinds Of Seal Wear
1. Gradually Increasing Leakage
Characterized By:
- Progressive wear and drying
- Increasing compression
- Progressive tear or erosion from initial nick.
- Fine score mark on dynamic surface.
2. Slow Uniform Leakage
Characterized By:
- Poor low-pressure seal ability
- Too little initial interference
- Loss of interference or squeeze due to wear or compression set
- Seal shrinkage after installation.
- Microscopic debris lodged under seal lip
- Scored lip due to passage of sharp particle under seal, leaving cut or nick.
- Seal lip nicked or cut during installation (note whether leak starts immediately after seal installation).
- Non-repetitive overheating hardens compound (which loses its ability to conform to dynamic surface deviations).
- Off-centre alignment puts all clearance on one side, all compression on the other (due to bearing wear, excessive side loads, etc.)
3. Erratic (Stop/Start) Leakage
Characterized By:
- Cold start up
- Intermittent eccentric loading
- Fibrous contamination working its way past seal lips.
- Unstable seal (twists & returns, cocks, etc.) usually caused by shock loading.
- Rod seal leaks slowly, tight wiper periodically dumps accumulated leakage .
- Fluid viscosity changes as temperature cycles (e.g. fork lift truck alternately entering and leaving cold storage area).
|

Will Not Work For You If You Have Sudden Copious Leakage
Characterized By:
- Extruded seal
- Torn seal lip
- Twisted seal
- Dramatic bearing failure due to excessive side load, shock, etc
- Spiral failure
- Massive infusion of contamination (due to incorrect fluid added to system, or to upstream introduction of dirt or wear debris).
- Slow rod seal leakage builds up behind tight wiper, then dumps…giving appearance of catastrophic seal failure. If leak rate then diminishes, look for slow leak or erratic leak causes. If high leak rate continues, look for true catastrophic leak origin.
- Reverse-pressure blowout of piston seal due to pressure trap or failure of opposed seal.
|

This is what happens when your scraper is dried and hard. The rod gets coated with excess oil and dirt causing more seal damage. Liquid Intelligence 235 rejuvenates scrapers which are your first line of defence.
How Does It Work?
|
All hydraulic seal materials tend to lose their plasticisers, shrink, oxidise, harden and become brittle with age.
Liquid Intelligence 235 will rejuvenate dried and hardened Buna-N, Polyacrylate, Neoprene Rubber, Styrene-Butadiene Rubber, and, Polyacrylonitrile hydraulic seals.
|
- Application Ratio: 50mls of additive per 1 litre of hydraulic oil.
- Extended Seal Life: Liquid Intelligence 235 seals permanently when used as directed.
-
Petroleum and chlorinated solvent free.
-
No Chlorides or Solvents: Made from pure phosphate ester, phenols and non-chlorinated and non-petroleum synergistic elements in a paraffin carrier.
-
Stops Leaks: An application of Liquid Intelligence 235 will work on hydraulic seals within one week.
-
Has very high temperature and pressure stability.
- Will not affect the viscosity of hydraulic fluids.
|

- Wiper Seals: Liquid Intelligence 235 rejuvenates wiper seals allowing them to return to size, preventing further contamination.
- O Rings: Liquid Intelligence 235 re-invigorates o ring material allowing flexibility to return for a tighter fit which prevents leakage.
- Rod Seals: Liquid Intelligence 235 restores the seals to tolerance and “un gums” frozen garter springs allowing for a tighter fit.
- Wear Ring: Liquid Intelligence 235 will aid in returning the seal to specification which reduces shaft wear minimizing costly shaft/ram replacement.
Please Note:
Normally a broken or cracked seal will leak profusely whilst a worn, hardened or dried seal will just leave irritating puddles of oil under your vehicle each day.
If your vehicle is not losing vast amounts of oil then I would recommend that you try Liquid Intelligence 235 before you start spending big money on mechanical repair and replacing seals.
Liquid Intelligence 235 has a long history of successfully repairing slow oil leaks in hydraulics.
It is not possible for Liquid Intelligence 235 to enhance the performance of seals that have mechanical damage ie. seals that are cracked, ripped or torn.
