Hose Assembly Instructions
1. Identify over all length (OAL) of hose assembly and the cut
off allowance (COA) length of ftting(s) on hose ends by use
of the ftting data table. Properly measure, mark and cut
hose to desired length using fne tooth hacksaw or a cutoff
machine. Care should be taken to ensure a square, clean
cut is obtained.
2. Air or solvent fush cut end of hose as necessary to produce
a clean hose ID prior to assembly. Place socket in vice and
screw in hose counter clockwise until hose bottoms. Back
hose out ½ turn.
3. Oil inside of hose and nipple threads liberally with Hoze-Oil.
Do not oil hose cover.
4. Screw nipple assembly into socket using a wrench on the
nipple hex until the nipple hex shoulders against the socket.
A 1/32” to 1/16” gap between the nipple hex and socket is
allowed for displacement angle adustment when elbow
fttings are used.
Inspection.
Examine hose assembly internally for cut or
bulged tube, obstructions and cleanliness. Clean ID of hose as
necessary. Swivel nuts should turn freely. Check the layline of
the hose to be sure the assembly is not twisted. Cap the ends
of the assembly to keep clean.
Special instructions for stainless steel fttings.
When
assembling fttings made with 316 stainless steel, lubricate the
threads of both the socket and nipple with Accrolube High
Effciency Lubricant
or equivalent metal
assembly lubricant.
