Pvc Nipple

Unread postAuthor: Model12 » Mon Jan 14, 2008 10:26 pm

At my local parts store where I get my PVC around the sprinkler valves they have grey pvc nipple this stuff is threaded so I use it for connecting valves, Ive searched It and found nothing but I was wondering if this stuff is safe to use on pneumatic guns? it says nothing about pressure on the label just "outdoor use" I have this on my guns and it would be a big bummer if it is not safe. My current gun I have taken to 90 psi and it was fine but I just want the satisfaction of knowing.

I haven't seen this on anybody elses guns but if anybody knows thanks in advance!

well i'm pretty sure they are for sprincler systems so is pvc. what i'm geting at is that they are probably ment to be used together in the same system so if the pvc can hold the preasure so should those.(in theory anyways) i don't know for sure though.

gray pipe (without a pressure rating) is almost always used for running wire or other electical uses. I don't think its safe to the same pressures etc. that pvc is, although i've never actually pressurized it. Im not sure for your exact location, but the building code here says all outdoor electrical must be run in that gray conduit stuff so someone doesn't try to cut it (thinking its pvc) and electricute themselves. This could be especially bad in certain situations. For example: I ran some 220 from my house -> garage and if it wasn't in gray conduit, in 50 years or w/e someone else has the house, thinking the line is shutoff (with a sprinkler system), cuts it, totally zapping themselves, and possibly sueing me or something.
my imput...sorry for length

Model12 - i have a few of those in my basement, they are normally used to connect sprinklers to threaded tees. they appear to be pressure rated but they are not thick enough to be sch 80 (dark grey sch 40?). 100 psi should be no problem for them (failure zone is probably around 200psi+ in good weather conditions)

Hmm, in the Lowe's near me the conduit is one isle from the pvc, on the same isle with all the brass fittings etc. It sounds like you guys made a positive ID so i'll shutup

It depends on location. In Canada for example, all pressure-rated PVC will be grey in colour.

really? wow i wish i lived in canada, i love the look of grey pvc, and the primer doesnt show up much in it, back on topic well if most pressure rated parts are grey then the nipple hes talking about should be ok.

Sorry guys I went to bed before I replied, ive seen it called pvc riser also (maybe on the rack) but it is a lighter Grey than the picture posted, but ive seen sch 80 and its almost that color just a tad bit lighter, I've been in the conduit isle and its like 2 away so its not that. I think its just grey pvc. btw I'm only taking this gun to 100 psi maybe, my normal pressure is 60-80 psi
