 Hi,
 
 I  have  following  components  in  Co2  setup  in  the  same  order:
 
 Aluminium  Co2  Cylinder  2  Kg
 ESAB  Dual  Stage  Co2  Regulator
 Reducing  Adapter  3/8  FBSP  to  1/8  MNPT
 Rotext  Soenoid  Vavle  1/8"  FNPT
 Clippard  Miniature  Needle  Valve  1/8"  MNPT
 Check  Valve  (connected  to  Needle  Valve)
 
 Interconnects  are  sealed  with  PTFE  tape  (except  main  connection  from  Cylinder  to  Regulator).  I  suspect  leakage  for  2  reasons:
 
 1.  The  cylinder  becomes  very  cold  as  if  kept  in  refrigerator.
 2.  The  cylinder  lasts  only  for  1-2  weeks  max
 
 I  am  not  able  to  find  source  of  leakage.  Can  anybody  help  me  about  how  to  make  the  interconnects  air-tight?  Is  there  any  need  to  use  sealant  or  washers?  I  tried  using  household  (tap)  washer  in  1/8"  interconnect  but  it  gets  deformed  and  stops  air  supply  completely.
 
 Thanks,

 use  shampoo  foam  /  soap  lather  to  check  for  the  leakage  source,  check  all  the  joints,  once  the  source  is  found  maybe  it  would  be  easier  to  rectify  the  problems.  just  my  2  bits.
