PSM Tuflok is a pre-applied nylon thread locking and sealing technology. A blue nylon patch is permanently bonded to a defined area of a fastener’s threads to create a reliable mechanical lock and seal. When assembled, the nylon compresses and deforms to fill voids and eliminate play between mating threads, providing resistance to vibration and leakage. The Tuflok process allows locking and sealing without liquid adhesives, curing time, or secondary operations.
The Tuflok Blue Nylon patch when applied is permanently fused onto the screw thread of the parent component, and increases the prevailing removal torque, allowing the screw to be locked in any position upon assembly.
Advantages
> Blue patch identifies Tuflok
> Reuseable
> Anti-vibrational
> Engineered torque flexibility
> Variable patch length and position
> Eliminates secondary locking features such as nuts, washers, etc.
> Automatically locks in any position
> Non curing
> Plate and patch
> Resistant to chemicals like alcohol, petroleum, oil, kerosene, diesel fuel and hydraulic fluids
Tuflok 180
Tuflok 180 is a blue nylon patch permanently fused to the screw thread. This process provides excellent vibration resistance and torque performance for all applications requiring controlled loading and
reusability.
Tuflok is effective, whether or not the fastener is fully seated, making it ideal for applications where continual adjustment is required.
> The Tuflok process consists of fusing the Blue Nylon 11 material onto a defined area of the male thread surface.
> Upon installation into the female threaded component, the nylon material is compressed filling the axial tolerances between the threads (1).
> The Tuflok process creates a strong metal to- metal radial loading on the flanks of the mating thread forms (2), which provides the locking action.
Tuflok 360
Tuflok 360 gives full circumference coverage (completely around the thread) and is suitable for applications requiring a fully re-usable high pressure seal against liquid or gas.
Industry Approvals
Our Tuflok product is approved to a wide range of industry standards including:- DIN 267 part 28, BS 7795:1994, General Motors, Ford WA970, Rover RES.22.FP.02, Jaguar JFS.02.01.04. Plus many other industry approvals.
Recommendations
HOLE PREPARATION
In all cases the female thread of the mating components should have the lead thread de-burred or countersunk to avoid damage to the patch material.
THREAD PREPARATION
To obtain optimum patch performance both male and female threads should be in accordance with class 6g/h (metric) or class 2 a/b (unified).
FINISHES
Tuflok can be applied to most popular plated finishes, as well as polymer and organic coatings.
CUSTOMER FREE ISSUE COMPONENTS
Parts manufactured from non-ferrous material should be supplied free from any surface contaminants. Variations in material structure can effect heating capability of the part during processing, which may result in torque variation.
High installation speeds can create galling of the threads affecting product performance. We currently process a range of Headed Components, Studs, Plugs and similar size parts.
We can apply our coating to ferrous or non-ferrous materials (Steel, Aluminium, Stainless Steel or Brass). With our on site Plating division we offer a complete Plate and Patch service.
This is a general guide to the products we currently process. We are able to process other components subject to evaluation.
