Quick question on Mcmaster-Carr

Unread postAuthor: jmeyer1022 » Thu Jan 29, 2009 12:21 pm

I've been looking for SDR-21 and was wondering if product #48925K95 is it? I haven't seen anything else that could be it
The site says SDR-21 specs are.
1-1/2" Size


1.900 OD


1.7 ID


0.090 Min Wall


0.358 Nominal Wt./Ft.

Sorry, I just reread your post, the specs you listed ARE for GB pipe, The part number you posted is NOT GB pipe...

McMaster doesn't have SDR21. They do have some metal tubing that would work, but it's not cheap. BCARMS would be your best bet for a golf ball barrel.

Edit: Spudtech has golf ball barrels too.

Are you in the US??? Find a local plumbers supply house, It's a fairly common pipe in plumbing...Sometimes refered to as class 200 or class 160,...

BTW, Anytime you can, Look in the phone book for plumbers supply shops, because pipe and fitting prices will be 1/3 to 1/4 of what Lowes or Home Depot, etc. sale for....

I built my 10ft GB cannon for what it woulda cost to build a 1" gun shopping at lowes....

I called a supply house nearby and the guy I talked to said they don't carry SDR products. This is the biggest supply house in CT. How long is BCarms on shipping usually? I've heard ranges from days to weeks.

Tractor Supply carries SDR 21, 1.5". You might have to travel to a few of them before you find one that has it in stock.

Didn't want to start a new topic. I got a mcmaster order today, but they replaced 2 alu. flat bars with 2 steel hinged things. Any idea what they will do? especially shipping, steel is way heavier then aluminum.
