Design Requirements

ThredSeals work by blocking all leak paths in a threaded fastener. They are used with standard bolts or screws and generally are seated on the nut side of the fastener. Unlike sealing directly underneath the bolt head, the nut side of the fastener has an additional spiral leak path, created by the threads, which will permit the fluid to wind its way through the helix.

ThredSeals have three wedge shaped protrusions on the inside of the seal. Since all standard screw threads have only a single V-shaped spiral channel, one of these wedges will always be in position to block the flow of fluid through this channel.

Applications

ThredSeals 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.  

ThredSeals 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.
