Thread: PP 256si gas inlet twisted off

  1. Default PP 256si gas inlet twisted off

    I have a PP 256si and the back gas inlet twisted off and need a replacement, is this something I can get local (PA) or is this something that needs shipped back? It’s less than a year old?

    Depends on where it broke and if you can get the broken piece out.

    Yeah,

    I broke one off the back of my 210EXT.

    They're not robust at their neck, and I just replaced the whole solenoid with one that had NPT pipe threads, so that I could use other fittings with it that are easier for me to find, like a 45 degree elbow and quick connect fittings.

    The threads on that inlet threaded into the OEM solenoid didn't seem to be a metric thread, as I had a gal at a Fastenal store check it.

    So, while I was waiting for a cheap solenoid with NPT threads (only was $18-$20) to arrive to me, I was able to just solder the fitting back togather for keeping the welder ready for use.

    A lot of Chinese stuff is BSP or BSPP.

    Yeah,

    I was getting blank stares from Fastenal staff, if I recall, who were otherwise pretty savvy when identifying thread types for me.

    For those who don't know, BSP or BSPP is like npt (pipe thread) with no taper. It's supposed to seal with an o-ring but many Chinese manufacturers just put some sort of clear hardening sealant on the threads with no o-ring.

    British Standard Pipe, British Standard Parallel Pipe. BSP or BSPT does have a slight taper, while BSPP doesn't. Much like our NPS (National Pipe Straight) used in the electrical industry. Also the thread form is 55° instead of the 60° of NPT. It can seal in several ways, like zoama mentioned with an O-ring (with or without a nut), with a crush washer and nut, a conical or flat seat, a sealing washer, or the infamous glue. The thread pitch is also different on some sizes.
