The next step involves preparing the nipples that will eventually seal the
boiler sections.
▶ Clean nipple with a rag soaked in solvents or gasoline and coat evenly
with sealant.
▶ Insert the nipple straight into the upper (Sz. 4.181.70) and lower
(Sz. 1, 82/50) hub of the rear section and pound home securely with
alternate heavy blows. Once pounded in, the upper nipple
(
Fig. 14, [1]) must protrude approx. 1 – 49/64 inches (45 mm)
and the lower nipple approx. 1 – 3/8 inches (35 mm) out of the
corresponding hubs.
▶ Remove any burrs with a file.

The packing grooves (
Fig. 15, [1]) must be clean and dry to enable
the sealant rope to adhere properly.
▶ Coat the packing grooves with adhesive (primer)

▶ Insert the flexible sealant rope (
Fig. 16, [2]) on the front of the
rear section, starting around the upper hub, into the packing grooves
(
Fig. 16, [1]) and press in lightly. At the butt joints, overlap the
sealant rope by approx. 3/4" (20 mm) and press firmly together.
▶ Unroll the required length of sealant rope from the spool supplied.
▶ Peel the backing paper from the sealant rope when inserting into the
packing groove (do not stretch).
