Tuflok®

Tuflok® is nylon patch the most widely used. Prelok is the sole licensee for France of this American process which was developed 20 years ago by the Nylok company.
Tuflok® is also known as the “blue patch” (Nylon® Blue Patch) in Asia and in the U.S.A.
The process of mechanical locking Tuflok® is specified on a large number of applications, from the standard screw to special aerospace fasteners.
The coated nylon blue Tuflok® patch is also known for its economic benefits. Tuflok® patch is one of the cheapest solutions on the market to prevent the threaded parts to loosen under constraint.
The Tuflok® patch is also recommended for its reusable characteristics which keeps its braking efficiency. The maintenance and disassembly operations are simplified and done at low cost. The Tuflok® is particularly recommended in applications where the adjustment during assembly or final use is necessary: screw, temporary positioning, … in general all applications subjected to vibrations.

Tuflok® is a nylon powder which is warmly deposed on a threaded part. While screwing, the nylon is compressed. The radial tension created by the elastic deformation of the product causes a retaining by the increase of friction. The retaining process is repositionable because the deformation of polyamide is partly reversible and enables to screw and unscrew the part for several times. The retain function is immediately active after screwing.

Tuflok® 180
The coating of Tuflok® 180 is applied at 180° on the periphery of the screw. It offers an excellent resistance to shocks and vibrations. It is also reusable several times. Tuflok® is even efficient on assemblies put under tension and is particularly recommended for adjusting screws.

Tuflok® 360
The coating of Tuflok® 360 is applied on the entire periphery of the unit. It is recommended for applications which need a high pressure sealing of liquids and gas. It is also reusable several times.
