Assembly terms and tips
Assembly instruction tips
Terms
• Skive—Removal of the cover material exposing the reinforcement
prior to fitting assembly.
• Dash Size—The hose or fitting size expressed in 1/16 of an inch.The
numerator of a fraction whose denominator is 16. Example: –8 or –08
is 8/16” = 1/2”.
• Nipple—The part of a hose fitting that goes into the hose tube.
• Socket—The part of a hose fitting that goes over the hose cover or
reinforcement.
• Mandrel—A round, properly sized, steel bar used for support during
assembly of the fitting or skiving the hose cover.
• Annular Rings—A series of concentric rings inside the socket.
Cutting the hose
1. To determine the “J” length (cut length of hose) from “OA” (overall
length) deduct “D” dimensions of both end fittings. Consult fitting
information pages for “D” dimensions. For hose assemblies with
SOCKETLESS® fittings, add 1/2” to “J” length.
Tip: If the old Aeroquip® assembly was the right length, simply
remove the hose fittings and measure the hose.
2. Cut the hose square.
3. Clean the hose bore.
Reusable fitting tips to remember for easy assembly
• Part numbers and dash sizes are indicated on fitting sockets.
• It is essential the fitting be mated with a compatible hose style with
the same dash size.
• Reusable fittings that have a notch in the socket serve as a reference
for the cover skiving length.
• Familiarize yourself with the assembly instructions before you start to
make an assembly.
• For hoses that require skiving, be sure to skive the hose to the proper
length and down to the wire reinforcement.
• Use Aeroquip 222070 hose assembly lube liberally on both the inside
of the hose and on the fitting nipple. (Check for compatibility.)
• Always cut hose square
• For volume production of hose assemblies, use Danfoss Assembly
Equipment.
Phase angle (offset)
When making double elbow assemblies, the following steps should be
followed to obtain the desired angle between elbows. Tighten both
elbows to maximum allowable gap between socket and nipple hex.
Start to position for relative angle between elbows. Finish assembly
by adjusting both elbows. Backing off to get desired angle should be
avoided.
