What are Thread Seals?

Fastener and Fitting Seals

Thread seals have been designed to seal the threads of machine screws, studs, and similar items. They are made in one piece, the rubber sealing element being molded into the metal retainer. They utilize the principle of controlled confinement of the elastomer, permitting metal-to-metal contact of facing surfaces.

Most fluid systems have fasteners that must be sealed. Thread seals feature an elastomeric sealing element molded in place within a metal retainer (washer). Although resembling a simple O-Ring groove concept, the mold in place fastener seal offers numerous advantages. Ideal for sealing small and miniature sizes.

Thread seals are safe and reliable seals for threaded devices. They are self-centering and non-directional, designed to seal directly against threads, without any special requirements. Thread seals can also offer considerable savings because they enable the use of low cost standard fasteners and full threaded fittings. They are easy to assemble and do not require special skills or tooling; simply push them on with a slight twisting motion and tighten the fastener.
