For other wall thickness butt welding, please indicate in the ordering number. Example: -JC-NT2-BW14M×2M means
butt welding outside diameter is 14mm, wall thickness is 2mm.
JC series gasket default material for copper, can provide PTFE gasket sealing detachable connector, add -T in the
ordering number back.Example: to order 1/2 NPT thread to 22mm×3mm butt welding with PTFE gasket sealing
detachable connector, the basic ordering number is -JC-NT8-BW22M×3M-T.

The model code of YT LOK detachable connectors contains material series the first end connection the second end connection The sequence of- : , , , .
the four parts is from left to right, Each part separated by The principle of the order between the two end connection"-". s as following:
1 See、 the top priorities as the first Another one as a second. .end connection end connection
2 When the two of the s were the same take the metric sizes as the fist For the same kind of threads, take、 , ,end connection the male threads as the
fist Same as butt welding or socket welding metric sizes as the fist then is inch sizes then is pipe., , , ,
3 After above principles take the big one as the first、 , .end connection
4 When the two s are identical, take any one as the first and the second will be omitted.、 end connection end connection end connection
