300PSI is the world's leader in annular treatment technology.  The Seal-Maker system is a revolutionary-patented composite, uniquely designed to repair injection well, production well, and sub-sea pipeline leaks.  Seal-Maker technology is based on it's ability to remain liquid until arriving at a leak point.  The composite's ability to recognize a leak allows it to immediately go to work. Utilizing a unique progressive solidification process, the composite is squeezed until a leak is completely and permanently repaired.  Residual fluid in the pipe remains liquid providing excellent corrosion inhibition. 

Proven
300PSI has proven the Seal-Maker system with results, time and again.  Discovered in 1995, the chemical repair system, quickly showed its extraordinary ability to perform successfully under extremely adverse conditions.  Today, and with over 400 repairs, the Seal-Maker system continues to show a success rate of 95%.  The 300PSI patented technology surpasses conventional methods of casing repair at a fraction of the cost.  No drill out is required and the results are permanent.
