Thread & Under-Head Sealants

Designed for hydraulic, pneumatic, and fluid-carrying systems, thread and under-head sealants deliver a dependable pressure-tight seal at both the threads and bearing surfaces of fastener assemblies. They fill the helical leak path and microscopic gaps that threaded connections inherently produce, preventing leakage of liquids and gases without the need for separate gaskets or additional sealing components. The result is a streamlined assembly that provides reliable sealing and passive retention in a single application.
