They are known for rigorously testing components under extreme operating conditions.\r\n

Application<\/strong><\/span><\/h2>\r\nThe T-Seals<\/a> were installed in a controlled bench test setup to verify final suitability for operation within oil & gas.\u00a0 The seals were required to perform in both static and dynamic (sliding) conditions across approximately 10mm – 15mm of movement.\u00a0 Testing was conducted using ISO 32 hydraulic oil at +10o<\/sup>C.\r\n

The Challenge<\/strong><\/span><\/h2>\r\nRockatek required seals capable of withstanding hydraulic pressures up to 35,000 psi while fitting around their existing fixed metalwork dimensions, which ruled out off-the-shelf sealing options. A fast turnaround was also critical to align with their testing timeline.\r\n

Hi-Tech Seals Solution<\/strong><\/span><\/h2>\r\nWe were able to rapidly design and deliver a batch of custom MH92 + MP89<\/strong><\/em> T-Seals engineered to Rockatek’s existing metalwork specifications and operating requirements, delivered within the lead time required to keep their testing on schedule.\r\n\r\nMH92 is our high-quality hydrogenated nitrile (HNBR) compound used as the primary sealing material; MP89 is our KasPex\u2122<\/a> compound, a high-performance virgin PEEK material exclusive to Hi-Tech Seals used as the back-ups.\r\n

The Results<\/strong><\/span><\/h2>\r\nThe T-Seals were subjected to hydraulic pressures up to 35,000 psi and performed reliably in both static and sliding movements throughout the testing program.\r\n\r\n“The latest batch of T-Seals we ordered were chosen for the lead time matching our testing timeline and previous stellar results. The seals were designed around our fixed metalwork dimensions. We were very impressed by the performance of these seals\u2026 I would highly recommend Hi-Tech Seals for their outstanding products, knowledgeable staff, and commitment to deliver quality products quickly.”\r\n\r\n\u2014 Jim Crowley, CEng, Pet.
