About Thread Sealants
We recommend using a Liquid Thread Sealant (Loctite™ 5452 or similar PTFE Thread Sealant) to seal
the Hydraulic components on your Lift.
Liquid Thread Sealant lubricates and fills the gaps between the Fitting threads, and leaves no residue
that could contaminate the Hydraulic Fluid. Other types of Thread Sealants (like Teflon Tape) can shred
during installation or removal and eventually enter the Hydraulic System.
Thread Sealant is not the same as a
Threadlocker
; Threadlocker holds assemblies tightly in
place to prevent them from loosening over time, and is not easily removed.
Thread Sealant can be used with most Hydraulic Fittings, although you probably only need to use it
with NPT Fitting connectors.
⚠ WARNING Always wear the proper protective equipment when handling Thread Sealant.
To apply Thread Sealant:
1. Make sure the Fittings and connectors you are going to use are clean and dry.
If you are adding Thread Sealant to a Fitting or connector that has already been used with a
different Sealant, use a wire brush to thoroughly remove the old sealant before adding more.
2. Skipping the top thread, apply a small amount of Thread Sealant to the first four threads of the
Fitting.
You only need a small amount because the sealant spreads to the other threads as it is tightened
into place. If you put too much, the excess liquid will be pushed out when the Fitting is tightened;
use a rag to wipe the excess.
3. Tighten the Fitting into the connector; do
not
over tighten the Fitting.
4. Allow the manufacturer-recommended 24 hours of curing time before pressurizing the system.
