Compression Fitting Assembly Procedure - Franklin Fueling Systems

Compression Fitting Assembly Procedure
On occasion it is necessary to use compression fittings
to extend or terminate UPP pipe work. This can be
achieved using the following assembly procedures.
Note: Compression fittings must only be used inside
containment, i.e. Sumps and Chambers, and
NOT direct-buried or used in contact with soil.
General Rules for All Fittings
1. Pipe ends must be cut square and smooth, i.e.
Perpendicular to axis.
2. Cut pipe to length allowing for correct insertion
depth into fitting.
3. Chamfer pipe bore.
4. Remove all burrs and swarf from pipe.

Compression Termination
1. Measure the pipe insertion depth of the fitting.
3. Tighten the locking nut until it contacts the body
of the fitting.
Mark should be
away from fitting
by L1 dimension in
chart
The distance from the mark to the fitting should
approximate the dimension L1 in the illustration below.
This is to insure that the pipe hasn’t shifted during
tightening.

2. Mark the insertion depth on the pipe end and
push the pipe into the fitting. Make sure the pipe
bottoms out in the fitting.
Insertion depth mark
should be level with the
end of the fitting.

Compression Terminations (11.321)
1. Fully insert support collar into pipe end.
Compression Terminations (11-032-EC)
1. Cut the pipe square, allowing for correct
insertion depth into fitting and remove all burs.
2. Seal is supplied pre-greased.
2. Disassemble fitting and slide locking nut and
sealing ring on to the pipe.
3. Mark the insertion depth on the pipe.
3. Fully insert pipe into fitting.
4. Push the pipe into the fitting through the clamp
ring until the first stop, meaning you have
reached the seal. Push the pipe through the
seal until you reach the pipe stop of the fitting.
Check the mark of the insert depth of the pipe
for correct assembly.
4. Tighten locking nut hand tight then wrench
tighten a further two and a half turns.
5. Tighten the nut hand tight plus one turn.

Compression Fittings
1. Cut the pipe square, allowing for correct insertion depth into fitting.
2. Chamfer the tubing and remove all burrs, paying particular attention to the bore of the pipe.
3. Remove the outer sleeve.
4. Insert the bolt head between the clamp bosses.

5. Mount the outer sleeve onto the pipe.
6. Lubricate the O-ring and insert coupling into pipe.

7. Slide the outer sleeve up to rear face of the coupling.
8. Lubricate the bolt / nut and faces of the clamp bosses.
9. Tighten the fitting until the clamp bosses meet.
