    What to use to seal old compressor head?

    thanks, but I think it was my post which wasn’t very clear. I was looking for advice on the compressor head flat mating surfaces with that little rubber ribbon integral seal. that is, something to hold pressure. I was wondering if anyone had something they’ve used with success and thanks for...

    What to use to seal old compressor head?

    I have an old craftsman air compressor which still can pump up but noisy as heck. I thought I’d try to quiet it down a bit with a muffler as it had just as a foam intake filter. (It didn’t work). I attempted to seal the gap between the muffler pipe and compressor head with some high temp Rtv...

    Ah, yes. I’m sure the hole saws are somewhere too. Thanks!

    What are these and their purpose? (Some kind of drill bit)

    I cleaned out Dad’s garage years ago when he passed and recently working to clean up mine. I found these with all the drills and router bits. What are they? I know they are drills but for what purpose? - eg. kind of look like something use in a router, drilling pilot holes on drill press...

    is flexible conduit required between disconnect box and air compressor pressure switch?

    As I've mentioned, I really appreciate all the advice and opinions which have been provided. It allowed me to do a project in an area where I have little expertise. At this point in my life, I could pay someone to do this stuff but the fun is in learning something new and gaining an appreciate...

    is flexible conduit required between disconnect box and air compressor pressure switch?

    Thanks - appreciate the education (and yes, also learned #8 is a pain to get into tight connections...)

    is flexible conduit required between disconnect box and air compressor pressure switch?

    Thanks - to clarify, I put the nm-b in a flexible conduit for the whip. I didn't leave it exposed. All indoors. Just curious - still technically not kosher?

    is flexible conduit required between disconnect box and air compressor pressure switch?

    Thanks for all the responses. Yes - it is a residential garage. I had the #8 nm-b in hand as there was exactly the length needed for the run from disconnect box to compressor switch left over from the 50ft roll I bought to run from subpanel to disconnect box. My main goal was to have the...

    is flexible conduit required between disconnect box and air compressor pressure switch?

    Thanks for the replies, sorry for not providing enough detail to prevent confusion! Everything is inside garage, not outdoors. The subpanel is mounted in an interior wall of garage. I ran the nm-b (I think Romex is a brand name?) inside the wallboard to ceiling where I used staples to hold to...

    is flexible conduit required between disconnect box and air compressor pressure switch?

    I ran the romex inside wall to rafters, across garage in rafters, down in conduit on outside of wall to cutout box.

    is flexible conduit required between disconnect box and air compressor pressure switch?

    I am installing 230V 5HP compressor. I put a new subpanel in garage and ran 8/2 romex from there to a disconnect box on wall by compressor. The disconnect box about 3' to 4' from the compressor pressure switch. Do I need to put the 8/2 romex in a flexible conduit between the disconnect box and...

    recommendation of air compressor switch

    This is how I damaged mine in first place. lifting strap slipped and went against cover of pressure regulator. I thought it looked ok but it didn’t shut down at pressure.

    220V to garage advice/sanity check

    Sorry if I was confusing, the plug is for the welder. I will wire the compressor into a disconnect box

    recommendation of air compressor switch

    Thanks - you are correct, it looks like the IR branded switch is a bit over $100 - about 3-4x the one linked above. I'll take a careful look at the one on the machine to see what options I have

    220V to garage advice/sanity check

    I'll look at the 8/2, if price difference isn't huge I might just wire 6-2 for possibility of going bigger at some point (even though unlikely). NEMA Type 6-50P, looks like big version of a standard 110V plug Since the distance from subpanel to plug is ~ 5ft - I was going to use the same wire...

    220V to garage advice/sanity check

    Thanks and perfect timing. I bought a 50ft prepackaged roll of 6-3 nmb and a disconnect box from Home Depot and had planned to do it today. Looked at disconnect box this AM and realized neutral was probably not needed - and was going to ask the question. I can return and buy w/o the neutral...

    recommendation of air compressor switch

    I have a 5hp TSN45 IR air compressor. I damaged the pressure switch moving it. I'd appreciate recommendations for a replacement. Should I just buy the IR replacement or get something else? I've heard Condor pressure switches are good, higher end compressors say they use them - but I can't...

    220V to garage advice/sanity check

    I found out air compressors selection is a religion and you have to be careful what you say. I wanted a Quincy or Emax but at 2.5 times the cost the 5hp, 80gal IR at Tractor supply, which is still more compressor than I probably need, I couldn’t bring myself to pay that much. Reviews aren’t...
