HYDRAULIC FITTINGS, HOSES & TUBING
A heavy wall tubing and multi-wire hose network carries the hydraulic oil from the reservoir to the
pumps and valves and then to cylinders and motors and finally back to the reservoir.
Operating pressure of the hydraulic system varies from model to model, consult the Hydraulic Pressure
Warning Sheet in this manual for your specific BARKO model.
Replace any tubes/lines which are bent or have become flat. There will be a restriction of fluid flow which
will make hydraulic action slow and cause heat. Replace hoses which show signs of wear, damage, or
weather-cracked rubber.
When making repairs on hydraulic system keep all parts clean and remove
all dirt from the area before you begin disassembly. Use caps and plugs to
keep dirt out of tubelines and openings.
PIPE THREAD SEALER
BARKO recommends the use of pipe thread sealer on all exterior pipe plug threads and
pipe fittings.
The main causes of air being introduced into a hydraulic system are loose connections and
fittings. This not only creates aeration in the fluid but also provides the risk of contamination
entering the fluid and components with the air. The easiest way to effectively reduce and
possibly eliminate this problem is to use an adequate pipe thread sealer at all connections and
fittings.
.
While other pipe thread sealers may meet specifications, the methods which BARKO uses are
Teflon tape, and
Locktite
Teflon Thread Sealer.
The sealer will form a flexible, non-hardening seal that can be easily broken at any time without
stripping the threads or damaging the pipes or fittings. It will also provide a non-shrinking bond
that will inhibit rust or corrosion in the threads and will not gall, seize, or block the threads.
APPLICATION
The pipe thread sealer is intended for use on threaded steel pipe in fixed installations. It
can be easily applied by the tube it comes in. This sealer is intended for use with petroleum
fluids only. Apply sealer sparingly and leave the first two threads near the end of the pipe or
fitting bare.
