The PSM Pre-Applied Thread Sealant is a specially formulated compound applied to screw or fastener threads before assembly to provide both sealing and locking functions in one step. This pre-coated design eliminates the need for manual application of liquid sealants, reducing assembly time, labor costs, and the risk of inconsistent sealing performance. Because the sealant is already dry to the touch and evenly distributed on the threads, Pre-Applied Thread Sealant ensures cleaner, faster, and more reliable installations. Once engaged, it activates under pressure to fill thread voids, forming a durable barrier against fluid and gas leaks while preventing vibration loosening.
Advantages
> Instantaneous high pressure seal
> Unlimited adjustment
> Superior Torque / Tension relationship
> Plate and Patch service
> Replaces hand applied tapes or gaskets
> Reusable
> High temperature resistance
> Controlled Patch position
Pre-Applied Thread Sealant Products
A range of dry-to-touch non-reactive coatings applied to the threads of screws, bolts, fittings or special components, eliminating the need for hand applied tapes or liquid sealant.
Applied as a water based suspension which is oven dried, finished parts are easy to handle and have no special storage requirements.
These processes offer high pressure sealing within the thread flank without any increase in removal torque. During assembly the coating is compressed,
filling in all axial tolerances between the mating threads, creating a barrier against water, oils, air and gases at high pressure.
> The Pre-applied process consists of applying a thin film of sealant onto a defined area of the male thread surface.
> The coating is non-toxic, dry to touch, ready to use and safe to handle.
> Upon installation into the female threaded component, a compressive force is developed, forming a barrier against liquid, oils and gases.
Industry Approvals
Our sealant product is approved to a wide range of industry standards including:- Ford WX201, Ford WSS-M18P12-A, Rover RES.22.FP.03, Varity Perkins PMS P.1.04. 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
A sealant can be applied to most popular plated finishes, as well as polymer and organic coatings.
CUSTOMER FREE ISSUE COMPONENTS
We would not recommend reusability of these products on parallel threads. Our experience is that reuse up to 5 times is achievable on tapered threads, however, tests should be conducted on your specific application.
We currently process a range of Headed Components, Studs, Plugs and similar parts. We can apply our coating to ferrous or non-ferrous materials (Steel, Aluminium, Brass or Stainless Steel and some plastic materials).
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.
