TufLok® and Nytemp® Patch All-Round for Thread-Locking and Sealing

The all-round version of the TufLok® and Nytemp® coating patch provides both thread-locking and thread-sealing functions.

TufLok® and Nytemp® All-Round are reliable, economical systems for sealing screw connections. The threaded parts receive a coating of highly elastic and abrasion-resistant polyamide on part of the thread. This fills the axial play between the screw and the nut thread, creating a tight and vibration-resistant connection. 

TufLok® and Nytemp® Patch All-Round Advantages

Sealing Function

The all-round patch creates a fluid- and gas-tight seal. 

No Curing Time

Screws with the coating patch can be used immediately.

High Material Resistance

The coating is resistant to alcohol, oil, gasoline and most thinners. It has an unlimited shelf life.

Versatile

The Nytemp® and Tuflok® coatings are suitable for adjusting screws and can be applied to almost all metals.

Reusable

Screws with a Tuflok® or Nytemp® patch can be reused several times.

How the All-Round Sealing Coating Works

TufLok® All-Round

The Tuflok® patch is a self-locking nylon element that bonds permanently to the thread of a fastener. When the patch is engaged, it creates a wedge between the fastener and the mating part, compressing the nylon and creating metal-to-metal contact opposite the patch. This results in positive vibration resistance and protects against loosening.  As an all-round coating, TufLok® creates an effective seal in the thread. 

Features: 

Blue all-round patch 
Temperature range: -56 °C to +120 °C

Nytemp® All-Round

The Nytemp® patch operates according to the same mechanism as the Tuflok® patch, but is suitable for higher temperatures. It is comprised of a high-temperature polymer permanently bonded onto the fastener thread. Due to the higher coating temperature, application is only possible on bright or phosphated threaded parts and stainless steel. 

Features: 

Orange all-round patch 
Temperature range: -56 °C to +200 °C

General Information on All-Round Coating Patches

Typical coating dimensions: 

Patch length: 4 to 6 threads 
Uncoated start of the thread: 1 to 2 threads

The internal thread must have a countersink (no sharp-edged thread inserts); otherwise, the patch could be peeled off when the screw is installed. Approximately two to three threads underneath the head should not be patched.
