thanks for the input "jdarco". there will be NO hot water going through these pipes. only cold well water.

1" SDR-21 has a pressure rating of 200 psi whereas 1" pvc sch40 has a pressure rating of 450 psi.

Ok, fair enough. Thank-you.

our company sells 1" sdr-21 pvc pipe. we use this in our low pressure watering systems that do not see pressures go beyond 1 psi. some of our customers have purchased this pipe not only for the use of our product but to plumb their entire barn with it. we have always recommended that they...

Ahh..yeah. I didn't think about the position tolerance. Thanks everyone. That's what I'll go with.

I would like to properly apply a geometric tolerance that aligns my metal insert mold part to the center of the hole in the plastic part. I'm not sure if I need the "Concentricity" or "Runout" tolerance. I would like the metal part to be within .010" of the axis on the hole in the plastic part...

ahh. thank-you.

When passivating stainless steel, in general, does the surface get slightly harder? If so, how deep into the surface does the passivation impregnate?

they are already passivated...

thanks kenvlach. i did end up calling the manufacture about this. they told me that they had a bad lot of material about a couple of years ago but has been improved since then. their take on it was that they have not had a single complaint about the armatures rusting except for us. they have...

actually, i have been so busy with other projects that i have not had time to call the mfg of this armature. horton is the company that makes it (http://www.hortonvalves.com/). perhaps a 301 would work but i have not looked into it.

i placed several parts in glass beakers. seperate beakers were filled with chlorox bleach (6% chlorine) and liquid swimming pool shock (12% chlorine). nothing was diluted. after 24 hours in the solutions it looked terrible. go here and download my pdf with pictures so that you guys can see...

i tried: high phos electroless nickel plate electroless nickel with teflon plate dry film (teflon) plate from imagineering finishing in south bend, in all three look like an Alka-Seltzer after about an hour or two in chlorox bleach. the standard 430 ss un-plated lasted longer than my plated...

Hello, i'm not use if i'm in the right forum...so be gentle. i have an off-the-shelf horton #ar7301 armature that is used in one of our water solenoids. th dimensions of this thing are about 1" long by about 1/4" in diameter. it's a fairly small part. anyway, my problem is that this thing is...

thanks Jim. i was hoping the picture might help. on item (1), hard to see from the pic, i have an energy director on the outer ring that helps bite into the rubber washer. the washer that i'm currently using is .130" thick and is 50 duro epdm. i originally had these die-cut but the tolerance on...
