ASSEMBLY IN HARDENED
PRE-ASSEMBLY BODY
1  In
order to ensure positive assembly, SEALEXCEL recommend pre-assembled
the tube and fittings in hardened pre-assembly Body.
|
2  Ensure
that the end of Tube is cut square within + 1/2° angle to the
tube axis. Remove the burs and sharp edges to the maximum chamfer
0.2 mm x 45° at both inside and outside edge of the tube.
|
3  Lubricate
the thread and cone of the pre-assembly body, Bite Ring and thread
of the nut.
|
4  Insert
the Nut and Bite Ring over tube end.
|
5  Screw
on Nut manually on to pre-assembly body until finger tight, hold
tube against the shoulder in the cone of pre-assembly body
|
6  Tighten
the Nut with wrench 1 turn from the finger tight position.
|
7  Loosen
the Nut, remove the tube from the pre-assembly body, check the
penetration of cutting edge. A visible collar fills space in front
of first cutting edge completely. It does not matter even Bite Ring
rotate on tube end.
|
8  Final
assembly in Fitting body Put pre-installed tube in to the fitting
body. Tighten the Nut with wrench by approx 1/2 turns beyond point
of clearly perceptible resistance.
|
9  Repeated
Assembly
Each time the fitting is disassembled, the nut
must be re-tightened firmly using the same torque as required for
final assembly
|
ASSEMBLY IN FITTING BODY WITHOUT
USING PRE-ASSEMBLY BODY.
1  Ensure
that the end of Tube is cut square within + 1/2O angle to the tube
axis. Remove the burs and sharp edges to the maximum chamfer 0.2 mm
x 45O at both inside and outside edge of the tube.
|
2  Lubricate
the thread and cone of the fitting body, Bite Ring and thread of the
nut.
|
3  Insert
the Nut and Bite Ring over tube end.
|
4  Screw
on Nut manually on to fitting body until finger tight, hold tube
against the shoulder in the cone of pre-assembly body
|
5  Tighten
the Nut with wrench 1-1/2 turn from the finger tight position.
|
6  Loosen
the Nut, remove the tube from the fitting body, check the
penetration of cutting edge. A visible collar fills space in front
of first cutting edge completely. It does not matter even Bite Ring
rotate on tube end.
|
7  Repeated
Assembly
Each time the fitting is disassembled, the nut
must be re-tightened firmly using the same torque as required for
final assembly
|
8  Final
assembly of Taper fittings
After applying oil on O-Ring,
tighten the Nut 1/3 of a turn beyond the point of noticeable
resistance
|
|
ASSEMBLY OF SUPPORT SLEEVES
1  Ensure
that the end of Tube is cut square within + 1/2° angle to the
tube axis.
Remove the burs and sharp edges to the maximum
chamfer 0.2 mm x 45° at both inside and outside edge of the
tube.
|
2  Support
Sleeve
|
3  Insert
support sleeve up to knurl.
|
4  Drive
knurl edge into tube (use soft hammer)
|
5  Ensure
support sleeve is flush with tube end.
|
6  No
tube necking after assembly
with support sleeve.
