HIGH-TEMPERATURE PATCH FOR LOCKING & SEALING – PRE-APPLIED TO SEELSKREW®, SEELBOLT® & SEALNUT® SELF-SEALING FASTENERS

HIGH-TEMPERATURE PERFORMANCE – Maintains torque values through temperatures from -70°F (-57°C) to +500°F (+260°C)

A specially formulated Nylon high-temperature Patch is generally applied to a minimum of 2-3 threads from the fastener end with 4-6 threads of coverage to assure ease of starting the nut/bolt assembly. When the mating threads are engaged, the patch is compressed creating a dam-like action on the opposite side of the coating resulting in very strong metal-to-metal contact.When the hightemperature patch is fully seated, it forms a positive lock that will not loosen, even under extreme vibration. This dam-like action adds to the high-pressure sealing characteristics of the O-ring & groove sealing design of our self-sealing fasteners.
