Primrose 532T Seal Saver is a conditioning and rejuvenating enhancement concentrate for use as a supplement to a finished tractor hydraulic-transmission, industrial hydraulic fluid or hydraulic fluid. The seal saving supplement in Seal Saver safely conditions and preserves all seal elastomers with a controlled expansive effect to reduce and eliminate leaks. In the process, it preserves seals and keeps them pliable.
Seal Saver prevents drying, shrinking, hardness and cracking of seals, the cause of excessive leakage and replacements.
Benefits:
Inhibits Foam • Superior Film Strength • Excellent Shear Stability • Helps Slow/Stop Leaks • Conditions Seals • Can Reduce Operating Temperatures
Extend the life of hydraulic fittings and stop/reduce leaks.

Common questions about 532T Seal Saver - Extend Seal Life!
-
What is Primrose 532T Seal Saver used for?
Primrose 532T Seal Saver is a concentrate added to a finished tractor hydraulic-transmission fluid, industrial hydraulic fluid or hydraulic fluid to condition seals and reduce leaks. Primrose says it keeps seals pliable and prevents the drying, shrinking, hardening and cracking of seals that cause excessive leakage and seal replacement.
-
How much 532T Seal Saver do I add to my hydraulic fluid?
Primrose recommends adding 532T Seal Saver at 15% where significant seal leakage exists, and at 5% to 10% for light to moderate needs. Add it to a finished tractor hydraulic-transmission fluid, industrial hydraulic oil or hydraulic oil, but not to fire resistant, polyalkylene glycol, polyol ester or silicone hydraulic fluids.
-
What hydraulic fluids should I not use 532T Seal Saver in?
Primrose says 532T Seal Saver is not for use in fire resistant hydraulic fluids or in polyalkylene glycol (PAG), polyol ester or silicone hydraulic fluids. It is made as a supplement to a finished tractor hydraulic-transmission fluid, industrial hydraulic oil or hydraulic oil.
-
Will 532T Seal Saver stop a leaking hydraulic seal?
532T Seal Saver can help slow or stop seal leaks. Primrose says it conditions seals with a controlled expansive effect to reduce and eliminate leaks, and its adhesive/cohesive agent gives the oil a non-drip property that by itself slows the rate of leakage. Primrose recommends 15% for significant seal leakage and does not say it repairs a seal that is already torn or cracked.
-
Does 532T Seal Saver help with foaming in hydraulic fluid?
Yes, 532T Seal Saver inhibits foam: it contains additional foam inhibitor along with its seal saving agent. Primrose notes that excessive foam in hydraulic fluid causes pressure build-up that can pop seals, and Seal Saver helps prevent this.
