FBT Female Branch Tee 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 ). Tube Handling
Scratches on the tube might cause leaks . it is , therefore ,
important to handle the tube carefully to reduce the risk of leaks
. Copper Tubing
If using copper tubing from a roll , hold the end of the tube and
roll the roll outwards allowing the tubing to lie on a flat surface
. 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 . Why choose us
Q: Could you offer the free samples ? A: Yeah, but it depends products, Pls contact us ina@pneuhydr.com or whatsapp 0086 15168536055 Q: What ' s your business scope ? A: Our business scope is service of exporter automation parts with full container, and sell air cylinder , air source treatment , solenoid valve , air valve, motorize valve , Brass valve, hydraulic valve, hydraulic cylinder, air and oil fitting, pressure gauge etc . Q: What types of products you can make ? A: We can make many kinds of stainless steel, brass ,aluminum materials processing .like high pressure Valve / solenoid valve / electric valve / water valve/pneumatic valve/air cylinder/hydraulic valve/hydraulic accumulator products and so on . Q: Can the product be made with our logo and brand ? A: Yes , of course , we can make . we are OEM supplier for years and professional to make . But you need give us the authorization if it is possible . Q:Can you provide original famous pneumatic and hydraulic,instruments brand goods ? A: Yes,We can supply like Festo,Smc,Ckd,Burket,Hydac,Rexroth,SMS,RSMT,Marsh ,Endress+Hauser etc. Q: Is there a warranty available? A: Yes, normally products is one year quality guarantee. Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads? A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America Q: How to convert pressure units: MPa, bar, psi, kg/cm ²? A: 1MPa=10bar≈145psi≈10kg Q:What usually causes the burnout of solenoid valve coils? A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc. Q: What should be noted for pneumatic components in high temperature or extremely cold environments?
