Threadlocker 242 is applied as a liquid to the threads of screws, nuts and bolts before assembly to keep them securely tightened, even when vibration occurs. Threadlocker also seals out air, water and grime to prevent rust or other corrosion from forming. Nuts and bolts that aren't corroded last longer and can be taken apart more easily. Standard hand tools can break the seal of the threadlocker, allowing you to remove treated nuts and bolts, which then can be reused.


This threadlocker is anaerobic (hardens in the absence of air) and requires contact with an active metal to cure. Active metals (those that tarnish, corrode or rust) include brass, copper, bronze, iron, soft steel and nickel. If both parts to be joined are made of inactive materials, Loctite Klean 'N Prime primer must be applied to one of the surfaces for curing to occur. Inactive materials include plated parts, stainless steel, galvanized steel, magnetite steel, pure aluminum, titanium, magnesium, gold, silver, plastic, cadmium, Iconel, zinc, natural or chemical black oxide and anodized aluminum.


Klean 'N Prime can speed the cure rate of Threadlocker 242. This is especially helpful when you are applying the adhesive to any material, active or inactive, in colder temperatures (below 70 F).

Titan Hydraulic Trailer Brake Installation

Video Transcript for Titan Hydraulic Trailer Brake Installation

All right, today on this old trailer, we're going to install the hydraulic brake assembly, part number T2351100. Now, we're going to start off our install to hub our _ inaudible 0:00:12 removed so we can show how to remove the vacuum plate. First off, we'll go ahead and disconnect the hydraulic line behind it. We're going to use a wrench to undo the fitting and remove the line. We're going to take the line and point it upward to help keep the fluid in the line. Next, we'll go ahead and unbolt the old vacuum plate.

There will be five nuts that we have to remove. We'll uninstall them and save the hardware and then we'll go ahead and reinstall them later. Once the hardware is removed, we'll go ahead and take off the vacuum plate. With the old removed, we can go ahead and install the new one. We're going to make sure that the wheel cylinder is situated towards the top.

We'll push it on and then we'll go ahead and reinstall the hardware. To secure our hardware, we're also going to use some Loctite, part number LT37477. With the new brake assembly in place, we'll go ahead and reinstall the hub. Next, we'll go ahead and reinstall the hydraulic line. We'll thread it back into the back of the wheel cylinder and tighten it down.

Our brake assembly is fully installed. Now, we'll go ahead and adjust the brakes. We'll peel off the cap at the bottom for the adjuster and we'll take our tool and go ahead and spin the adjuster to tighten up the brakes. Now, we're going to tighten them up just enough where the wheel stops moving by hand, and then we'll go ahead and back off about 10 clicks. There should be a slight drag when you're through.

Next, we'll go ahead and repeat the same process on the driver's side. With that, that will finish it for our install of the vacuum plate, part number T2351100.

  • What is Loctite 242 Made Of
  • Loctite 242, # LT37477, is made of a liquid synthetic polymer that cures in an anaerobic environment, which basically means that it will not harden in the presence of air, and it cures when it is sandwiched in the threads between active metals like a nut and bolt. I have included a table, see link, that shows the make up of Loctite for you to review.
