    Dears My Friends,

    hope all well and safe,

    i have bought a SCOTT air cylinder, i am looking to find out the thread size of the inline valve of my SCOTT air cylinder TC-SU-5134 , DOT-SP-10915-4500, OP 437674 , Luxfer P/N L87G

    so, that i can choose the right valve to my air cylinder,

    i have already one valve with M18X1.5 thread, but it is smaller for my SCOTT air cylinder, my tank needs bigger fittings which i am looking for your kind help in this matter,

    i have found below link which i think my tank thread size is 0.875-14 UNF , plz correct me if i am wrong.

    thanks in ADV,

    Best Regards,
    Hemn .M


    Hi Hemn,

    That is the way I read it.  7/8-14 UNF.  That is what I put in my Luxfer SCBA tank.

    I’m a bit weird.  I went with a DIN 300 valve as I use a SCUBA compressor to fill my tanks and my fill adapters work with either the DIN200 or the DIN 300 connections.  I’ve got many dive tanks with the DIN 200 and I can live with lower fill pressures in most of my PCPs.  The standard for SCBA tanks is CGA346 and CGA347 IIRC.




    Thank you very much dear Nugria, appreciate your reply, i will order this from , as i brought the link below, i hope it will be the right siaze, 🙂
