Flange Spreader
Parts and Operating
Manual

General Information
The Flange Spreader is used to efficiently separate 150 –300 pound flanges for
the replacement of the flange gasket or the application of new sealant on the
flange face. The Spreader, which attaches to the flange mounting hole, spreads
the flange faces without the risk of damage to the flange sealing surfaces. The
wedge action of the Flange Spreader spreads the gap between flanges up to 1
1/4" (31.8mm) with 100 ft-pounds of torque applied to the Manual Flange
Spreader and yields up to 12,000 lbs. of spreading force.
Hydraulic Kits (D104-KIT) are required for the operation of the D101, D102
and D103 Hydraulic Flange Spreaders.
D100
The Manual Flange spreader is designed for use on 2” to 12” (51 – 305mm)
300-pound flanges. The hex nut at the top of the flange spreader requires a 1
1/4" wrench or socket. The dimensions of the Flange Spreader are:
A. Overall height –10 ½ inches (267)
B. Width –8 7/8 inches (225)
C. Maximum width between pins –3 9/16 inches (90mm)
D. Height between the top of the pin and the bottom of the cross bar –1
3/32 inches (28mm)
D101
The D101 Hydraulic Flange Spreader is designed for use on 12” to 24” (305 –
610mm) 150 & 300-pound flanges. The dimensions of the Flange Spreader are:
A. Overall height –14 ½” (369mm)
B. Width –2 ½” (64mm)
C. Maximum width between pins –9 ½” (241mm)
D. Height between the top of the pin and the bottom of the cross bar –1
½” (38mm)
D102
The D102 Hydraulic Flange Spreader is designed for use on 26” to 36” (660 –
914mm) 150 & 300-pound flanges. The dimensions of the Flange Spreader are:
A. Overall height –14 ½” (369mm)
B. Width –2 5/8” (66.7mm)
C. Maximum width between pins –13” (330mm)
D. Height between the top of the pin and the bottom of the cross bar –1
½” (38mm)

D103
The D103 Hydraulic Flange Spreader is designed for use on 2” to 12” (51 –
305mm) 150 & 300-pound flanges. The dimensions of the Flange Spreader are:
A. Overall height –13” (330mm)
E. Width –2 ½” (64mm)
F. Maximum width between pins –8 ½” (215mm)
G. Height between the top of the pin and the bottom of the cross bar –1
3/8” (35mm) D104-KIT
A Hydraulic Hand Pump with reservoir hoses and quick disconnect, such as the
Enerpac model 82C-OHP (maximum output of 10, 000 psi (689 bar) or equal,
can be used to actuate the Hydraulic Flange Spreader.
Operation
Two (2) Flange Spreaders and Hand Pumps with Reservoirs are required for
spreading the flange to avoid damage to the flange sealing face.
A - 1St Flange Spreader
1. Center the wedge of Flange Spreader over
the space between the two flanges.
2. Center the stud of the Holder Ears in the
flange hole and push the Holder Ears in
the direction of the arrows shown in the
picture.
3. Apply hydraulic pressure or tighten the nut
at the top of Flange Spreader so that it is
held in position on the flange.
B - 2nd Flange Spreader
1. Center the wedge of the second Flange
Spreader over the space between the two
Flanges on the opposite side of the first
Flange Spreader.
2. Center the stud of the Holder Ears in the
flange hole and push the Holder Ears in the
direction of the arrows shown in the picture.
3. Apply hydraulic pressure or tighten the nut
at the top of Flange Spreader so that it held
in position on the flange.

C –Spreading the Flange Faces
Once the above operation has been completed, apply pressure to each Flange
Spreader equally to avoid damage to the flange sealing face.
Maintenance
The Flange spreader should be cleaned and inspected after each use in case of
any damage, such as cracks, to the flange spreader. An Enerpac Model RC-53
hydraulic cylinder or equal can be used, if the hydraulic cylinder of the
Hydraulic Flange Spreader requires replacement.
