FLUID POWER 6 Weatherhead Hydraulics
FIELD ATTACHABLE COUPLINGS — 425 “N” SERIES
• Hose End Series: 425 “N” Series • Typical Application : High pressure applications such as construction, farm implement and industrial equipment • Compatible Hose : H425 • Pressure : Determined by maximum pressure for hose size • Material : AISI/SAE 12L Carbon Steel • Plating : Zinc; Yellow Dichromate finish • Advantages : non mandrel assembly. Wide variety of applications because of its use with H 425 hose.
Assembly Instructions : Due to the high torque required to assemble larger sizes, it is recommended that 425 “N” series hose ends be assemled with the T-300 Assembly machine 1. Lubricate insert threads and I.D. of the hose 2. Measure from end of hose and mark the socket depth 3. Screw hose into socket to the depth marked on hose 4. Screw insert into socket until insert touched socket.
