I guess this has been asked before but "seal" and "oil" just produces masses of hits.
10mm pipe for interconnecting the isolator, filter, fire valve, etc. PTFE just seems to almost dissolve. The oil is currently just past the isolator and it's seeping.
Many thanks for any help

Ideally you should use flared joints, but you would need a flaring tool.
Compression joints are also possible. Solder joints will work for a
few years but are not advised as the oil can disolve the solder.



Soldered joints are not *allowed*...
