P Type Plug Stainless Steel 316L Tube Fitting Plumbing Fitting High Quality Sanmin
Tube Fittings Description
The tube fitting is a mechanism used both to seal and to grip
tubing . The mechanical advantage and geometry of this kind of
fitting produces a leak – tight assembly .
To assemble , simply insert the tube into the complete assembly
until the tube bottoms – out against the shoulder of the fitting
body . The two ferrules are driven forward between the nut and
fitting body using the mechanical force created by rotating the nut
clockwise . The Back ferrule is driven against the tapered rear of
the front ferrule is driven by force into the tapered mouth of the
body .
The rear ferrule is swaged radially inwards on the tube while
lifting the front ferrule out to form a full – faced seal on the
tapered surface of the body .
The 1-1/4 Turn of the nut from the hand tight position assures
consistent drive of the sealing members . This ensures an effective
seal against high pressure as well as ultra high vacuum conditions
.
Tube cutting
Two different methods can be used to cut tubes :
1 . Tube Cuter
2 . Hacksaw
Hacksaw Cutting
In order to cut the tube with a hacksaw and get square ends , the
tube must be cut with guide blocks
This method of cutting necessitates deburring of the tube ends.
Warning
Do not hold the tube in a vise in the place where it will be
inserted into the fitting ( the vise will leave a mark on the tube
that may cause leaks , and might cause ovality ).
Some Recautions to be taken
1.Tubes must not be dragged on the floor .
2.Tubes must not be dragged out of a tubing rack , especially in
case of large OD tubes
Inspection Tubing
Use : This is a “ No- Go ” Gauge and should be used as follows :
Make up to fitting according to the following instructions : 1/4
inch ( 6mm ) , 3/8 inch , 1/2 inch ( 12mm ) – make up 1-1/4 turns
from finger tight . Check gap between nut and body , using the
appropriate sized gauge . If the gauge slides easily into the gap ,
tighten the nut further until gauge can not enter the gap
Tube Selection
Four variables must be considered when ordering tube for use with
fittings :
1. Material
2. Tube wall thickness
3. Tube surface finish
4. Tube hardness
Tubing should comply with standard ASTM A213 or ASTM A269 , be
seamless , and fully annealed .
The tube must be red of scratches and suitable for bending and
flaring .
