INSTALL HYDRAULIC CONNECTIONS
STANLEY recommends you use hose lengths of 25 ft/8 m
with 1/2 inch/12.7 mm inside diameter. Hoses must have a
working pressure rating of at least 2500 psi/175 bar. Hose
ends must have male threads compatible with H.T.M.A.
quick disconnect fittings (NPT).
H.T.M.A. approved quick disconnect couplings are installed
to hydraulic hoses so that the direction of oil flow is always
from the male to the female coupling. Additional fittings,
such as reducers or adapter fittings, are not required.
If adapter fittings are used, they must be approved steel
hydraulic fittings meeting a minimum operating pressure
rating of 2500 psi/172 bar. Do not use galvanized pipe
fittings or black pipe fittings.
Use thread tape or pipe joint compound when installing
quick disconnect couplings to hose or tool fittings. Follow
the instructions furnished with the selected thread sealant.
DO NOT OVERTIGHTEN THE FITTINGS.
Connect the pressure hose to the bottom (male) fitting.
Connect the return hose to the top (female) fitting.
