Reed RG26 Series Roll Groover
Description and Specifications
Description
The Reed RG26S Roll Groover is designed to form stan-
dard rolled grooves in steel, stainless steel, PVC, and alu-
minum pipe in 2-6" schedule 10, and 2-3" schedule 40.
The Reed RG26CU Roll Groover is designed to form stan-
dard rolled grooves in 2” to 6” copper tubing. The groove is
formed by a groove roll which is fed into the pipe wall. The
pipe is supported by a drive roll, which is relieved to permit
pipe wall deformation. The formed grooves comply with the
specifications required for mechanical coupling systems.
The only adjustment required is for the depth of the groove.
Designed for ease of use and portability, the RG26 Series
Roll Groover provides a practical solution for manual on-
site and in-place roll grooving.

Tube/Pipe Preparation
For satisfactory tool operation, the following tube/pipe prepa-
ration tips should be carefully observed:
1. Tube/pipe must be square cut.Do not use a cutting torch.
Note: When adjusting for roll groover depth, the trial
groove pipe should not have a large burr protruding in-
ward. Use a suitable tool for deburring the pipe or tub-
ing. After the groove depth has been set, deburring of
the pipe is not required.
2. The end of the tube/pipe, both inside and out, should be
cleaned of coarse scale, dirt or other materials which
might interfere with or damage the grooving rolls or dis-
tort the groove. Large weld beads are to be ground to
permit smooth rolling operation.
Pipe Set-Up
The RG26 is an orbital roll grooving tool which rotates
around a pipe held stationary. The pipe may be held in a
pipe vise during grooving. The RG26 also grooves piping
in a depressurized, in-place piping system.
Pipe Vise Set-Up
The choice of grooving location in the shop or field should
take into account the following factors:
• Pipe handling requirements
• Working space requirements for the tool and pipe
• Anchoring requirements for the pipe vise
Procedure
1. Securely mount pipe vise (chain type) on a secure stand or
workbench. Pipe vise should be mounted flush with or over-
hang the edge of the stand or workbench so, when the tool is
mounted on the pipe, the tool will rotate freely around the pipe
and not be obstructed by the bench or stand.
2. Secure pipe in pipe
vise, anchored to
hold securely the
weight of the tool
(21 lbs.) Position
the pipe to over-
hang the pipe vise
approximately 5 -
12" so the tool can
rotate in an unob-
structed manner.
(See Fig. 1.)

RG26 Series Roll Groover Operator’s Manual
809-50356
Groove-In-Place Set-Up
Previously installed piping may be grooved with the RG26,
providing the piping is securely supported.
NOTE: Pipe hangers must be able to accommodate the
weight of the 21 lb. (9.55 kg) RG26 plus the manual effort
to operate the tool (approximately 20 ft.-lb. torque) during
grooving.
WARNING
Piping systems must always be depressurized and
drained before attempting disassembly.
Failure to do so could result in serious injury, property
damage, joint leakage or joint separation.
Mounting Tool
1. Retract the upper roller fully by turning the brass feed nut
counterclockwise.
2. With the hex drive nut down, insert the nose of the body
into the pipe end. Push the tool onto the pipe until the
pipe end stops rest against the pipe end. (See Fig 2.)
3. Draw rolls together by turning the brass feed nut clock-
wise. Continue tightening until the grooving rolls are in
light, but firm contact with the pipe.
Adjusting Groove Depth
The Depth Stop Collars must be adjusted for each tube/
pipe size or change in wall thickness. Groove diameter,
identified as the “C” dimension for each tube/pipe size, is
listed under Standard Roll Groove Specifications - Steel
and Other IPS Pipe. For convenience, a “C” Diameter Chart
for the most common pipe sizes is also on the tool.
1. Unlock the depth stop collars by turning them in opposite
directions until they are separated.
2. Locate the groove depth gauge attached to the tool which
is identified with the pipe size to be grooved. Turn the
depth stop collar, closest to the trunnion, until the dis-
tance between the collar and the top of the trunnion is
equal to the groove depth gauge thickness. Use the
groove depth gauge like a feeler gauge. (See Figure 3.)
Fig. 3. Setting Gauge Depth
3.Turn the second collar until both are locked firmly against
one another, maintaining the gap set with the feeler
gauge. Replace the depth gauges back into the holder.
4. Prepare a trial groove by tightening the brass feed nut
the recommended turn increment, and then by turning
the crank nut clockwise until the roll groover has made
one full revolution around the pipe. (See Fig. 4.)

Fig. 5. Turning crank handle
Note: Trial groove pipe should be deburred for best results.
A burr on the inside of the pipe will raise the pipe away from
the drive shaft, causing inaccurate set-up adjustment. After
proper groove depth has been verified by the trial groove,
deburring of the following pipes is not required. See Step 1
of “Tube/Pipe Preparation”
6. After a trial groove is prepared and the tool is removed
from the pipe, carefully check the groove diameter (“C”
dimension), a charted under Standard Roll Groove
Specifications - Steel and Other IPS Pipe, page 8, and
Drawn Copper Tubing Groove Specifications, page 9.
The “C” dimension is best checked with a pipe tape. It
may also be checked with a dial caliper or narrow land
micrometer at two locations, 90°apart, around the
groove. The average reading must equal the required
Groove Diameter.
CAUTION
The “C” Dimension (groove diameter) must always con-
form to specifications under Standard Roll Groove
Specifications, page 9, to ensure proper joint perfor-
mance.
Failure to do so could result in personal injury, prop-
erty damage, improper installation, joint leakage or joint
failure.
7. If groove diameter (“C” dimension) is not within tolerance,
adjust the depth stop collars to obtain the proper dimen-
sion. To adjust for a smaller groove diameter, turn the
depth stop collars counterclockwise. To adjust for a big-
ger groove diameter, turn collars clockwise. A quarter
turn either way will change the groove diameter by .017"
(.068" per full turn).
8. Prepare another trial groove and check the groove diam-
eter again. Repeat Steps 6 and 7 until groove diameter
is within specification.
Grooving Operation
NOTE: Reed RG26 tool is designed only for roll grooving
tube/pipe of the appropriate sizes. Grooving of tube/pipe
other than that recommended may not produce grooves of
proper tube/pipe end configuration or groove dimensions
necessary for joining.
Before Grooving:
• Review Safety Precautions before operating the tool.
• Check to be certain tube/pipe has been prepared
properly as detailed in
Tube/Pipe Preparation.
• Check to be certain pipe is properly supported as
detailed in
Pipe Set-Up.
• Check to be certain the tool is properly mounted on
the pipe. See
Mounting Tool.
• Check to be certain the depth stop collar is adjusted
correctly. See
Adjusting Groove Depth.
5.Continue turning the feed nut and cranking the tool around
the pipe. Once the jam nuts rest against the trunnion,
continue to crank the tool around for one more revolu-
tion. (See Fig. 5.)

CAUTION
Keep fingers, clothes, hair and objects other than tube/
pipe away from the rotating tool. Use safety glasses,
hardhat and appropriate footwear. Failure to do so
could result in personal injury.
1. Advance the feed by turning the feed nut clockwise by
the amount show in Table 1. Feed rates for the RG26
vary depending on material and pipe wall thickness.

Note: Over-tightening (overfeeding) will result in shortened
bearing life and other tool damage. Over or under-tighten-
ing could result in the tool “walking” off the pipe and eventu-
ally becoming disengaged from the pipe.
2. Place the ratcheting crank handle onto the drive hex.
Crank the drive hex nut clockwise until the tool travels
one full turn around the tube/pipe.
3. Advance the feed by turning the brass feed nut clock-
wise by the amount show in Table 1. Crank the tool an-
other full turn around the pipe.
4. Continue grooving by advancing the feed (Table 1) and
cranking the groover around the tube/pipe until the depth
stop collar comes in contact with the trunnion. At this
point, the brass feed nut can no longer be tightened.
Crank the tool at least one more full turn around the tube/
pipe after full groove depth is achieved.
5. After dismounting tool from pipe (see below), check
groove depth to ensure groove meets groove depth speci-
fication. NOTE: Groove Diameter should be correct for
the diameter and wall thickness of tube/pipe for which it
was set under Groove Diameter Stop Setting procedures.
Groove diameter should be checked periodically and ad-
justed as necessary.
Dismounting The Tool
1. Crank the tool until the drive hex is located in the down
position.
2. Turn the feed nut counterclockwise to retract the upper
roll arm to the full open position.
3. Lift the tool and remove it from the pipe. (See Fig. 6.)
Maintenance
1. Keep tool clean for best and safest performance.
2. Lubrication:
a) After approximately eight hours of operation, grease the
bearings at the three grease fittings on the tool. Use a
No. 2 EP Lithium base grease.
b) Weekly apply a light oil (SAE 10W-30 or equivalent) to
the threads where the feed screw passes through the
feed nut. Also, oil should be applied to the shoulder bolts
which hold the roll arm to the body, the feed screw to the
roll arm, and at the trunnion pivots.
