Can I use these SS 1/2" nipples?

http://www.mcmaster.com/#stainless-steel-pipe-fittings-and-pipe/=bs5uuj

They're 1/2" NPT for $2.48. Normally the online places sell them for $4-5/each. They're schedule 40 which I have no idea if this matters. 304 stainless. The only thing I notice is they are pipe construction of weldless. They have the near identical piece here http://www.mcmaster.com/#stainless-steel-pipe-fittings-and-pipe/=bs5wdv

that's schedule 80 with seamless pipe construction. Does this even matter? I would be using these nipples for a gas bar/manifold in a brew stand so they would be welded into the stand with a tig welder.

Thanks all.

Murray Equipment http://murrayequipment.com has those same nipples for $1.54. They have the best price on pretty much all the ss fittings from what I have found so far. A lot of guys are buying their 1.5" ss tubing for the RIMS build.

There is a standard in pipe fitting and schedule 40 is one of the standards. Schedule 80 would be the same outside diameter but thicker walled. You would only need schedule 80 if you were dealing with really high pressure.

Hope this helps

Thank you. Does the welded vs seamless construction type matter at all?

To be honest I have not used them for what you are doing but I have used the regular schedule 40 "black pipe" which is just regular steel for running natural gas. I do not think that was "seemless" pipe and again I think the seemless stuff is for much higher pressure than the natural gas or lp pressure coming from a normal bbq type propane tank. I don't even think the higher pressure propane tanks would be running high enough pressure to need schedule 80 or seemless pipe but I have no experience with that and you would definetly need to research that.

Don't forget the stainless pipe is already going to be stronger than the normal steel schedule 40 stuff used in residential building.

seamless vs welded, and sch 40 vs 80, isnt going to matter in your application. any of the pipes mentioned will be good for use so just go with the cheapest.

here is some more information if you wanted to know what pipe schedules mean

for a gas bar it would not matter, the like bachhus said the seamless tubing is rated for a higher pressure. i used it on my keggles, but only for sanitation reasons, the cheap ones should be more than adaquit for a gas bar so long as your stand is also stainless.

I'd pay Mcmaster the premium price due to how solidly they run the business. The stock indicator is accurate (completely unlike Murray) to say the least.
