Vibra-Tite VC-3 Threadmate is one of the most versatile thread lockers available. An alternative to traditional liquid lockers, which cure to form a complex bond, VC-3 is a proprietary blend of thermoplastic elastomer resins designed to remain flexible and absorb vibration. The combination of inert/non-reactive amorphous resins creates a tough, semi-solid layer inside the threads of a mated joint. VC-3 damps the vibrational energy transferred between the threads of a mated fastener, preventing fastener loosening and loss of clamp load. These unique differences make VC-3 coated fasteners adjustable, removable, and reusable.
An acrylic polymer that damps and absorbs vibration
Will not harden like anaerobic thread lockers
Works with metal, wood, plastic (*see table), and more
Fasteners are easily adjusted, removed and reused
Works on fasteners of any shape or size, from tiny eyeglass screws to large construction bolts
Works with internal or external threads
Meets low out-gassing specifications (NASA SP-R-0022A, per ASTM E 595)
Parts coated with Vibra-Tite VC-3 can be stored indefinitely before use.
Versatile Adheres to ferrous and non-ferrous metals, most platings, wood, and plastic (see table) screws.
Versatile Adheres to ferrous and non-ferrous metals, most platings, wood, and plastic (see table) screws.
Multiple reuses Steady pressure and standard hand tools allow parts coated with VC-3 to be easily adjusted, removed, and reused.
Minimizes galling / stripping Since Vibra-Tite VC-3 remains a thick, resilient, viscous resin, its cold flow properties actually minimize the galling or stripping of soft threads during reuse.
Underwater installation Unlike anaerobic thread lockers, VC-3 can be air dried and installed into a mating part under fresh and salt water.
Shake well before each use. Apply VC-3, a length of 1 to 1 ½ times the fastener diameter, filling threads 30-50%. Although material will be dry to touch within minutes, allow VC-3 to dry for at least 30 minutes (the longer, the better), depending on part size. Fasteners are then ready for assembly or to be stored for later use.
From tiny eyeglass screws to huge construction bolts, Vibra-Tite VC-3 is ideal for fasteners of any size.
Mounting ski / snowboard bindings, plates and inserts.
RC models (Drones, Airplanes, Helicopters).
Bolts on motorcycles.
Specifications:

-65˚F to 165˚F (-54˚C to 74˚C)
Reusability
Using steady pressure and standard hand tools, parts coated with Vibra-Tite VC-3 can easily be adjusted, removed, and reused up to 5 times.
Minimizes Galling/Stripping
Since Vibra-Tite VC-3 remains a thick, resilient, viscous resin, its cold flow properties minimize galling or stripping of soft threads during reuse.
Engagement torque
Moderate
Breakaway torque
No distinct break; slow, fluid release as material cold flows
Best priced around great and speedy service!
Also is the better of the 2 options since it is rated at 5,000 psi, not that I go to that high of pressure but I like the safety and security knowing that my chances of it blowing up in my face are a whole lot better and I can also purchase replacement seals for them at the same shop!!!
I bought the DC PTT because I know and trust the DC quality/durability to hold up to using every day. And so far it’s the best PTT I’ve used. I have a couple other no-name PTTs and the cable sheathing is crumbling and falling off. The DC PTT has worked even in sub zero cabin temp conditions when I didn’t have a functioning heater. I bought two to have a spare but the first one has been working great for 300hrs so far.
