Press System — Installation Instructions
Installation Instructions for 2 1/2" - 4"
Press Fittings and Valves
WARNING: To prevent serious injury, the pressing tool, battery charger
(if applicable) and pressing chains should be inspected according to the
procedure outlined in the pressing tool instruction manual prior to beginning
installation.
Failure to clean pressing chains can result in an improper connection that can
lead to extensive property damage.
Preparing the Copper Tube
1. Select clean, undamaged copper tube and cut to the desired length. Cut tube
end square using a tube cutter or ne-toothed saw. Do not crimp over dam-
aged, scratched, gouged, or otherwise damaged tubing. Do not crimp over
etch print streams on tubing (Figure 1).
2. Deburr the tube inside diameter using a half-round le or deburring tool.
Remove any copper shavings or lings (Figures 2 & 3).

3. Deburr the tube outside diameter using a half-round le to prevent damage to
the EPDM seal (Figure 4).

4. Clean the tube end of all contamination, oils and shavings. A smooth transition
chamfer is recommended to ease tube insertion past the seal. (Emery cloth or
sandpaper to clean the tube or remove oxidation should not be used.)
Inserting the Tube into the Fitting or Valve
1. Check the tting to make sure that the seal is in place and is free of oil or
grease. Only original NIBCO
®
EPDM seals are to be used when making a
press connection with NIBCO Press System ttings and valves. If it is neces-
sary to lubricate the seals, use water only. DO NOT use any petroleum-based
lubricants (Figure 5).
Figure 5: Check for EPDM seal
WARNING: Never lubricate the EPDM seal in a NIBCO Press System fitting
or valve with anything other than water. Oil-based lubricants, dirt or debris may
damage the seal. An improper seal can lead to extensive property damage.
2. Mark the proper insertion depth on the tube with a permanent marker prior to
insertion, based on insertion depth chart. Refer to minimum insertion depth
table for correct depths.
3. Insert the tube into the fitting or valve using a twisting motion. Make sure
that the tube is fullly inserted into the fitting or valve.
WARNING: If tube is not inserted to the proper depth, an inadequate seal
may result.
CAUTION: Tubing that is difficult to insert may have burrs or could be
out-of-round. Burrs must be removed and tubing end should be undamaged.
Make sure tube is inserted to the proper depth. Failure to do so may result in
an improper seal.
