Good fitting link?
Hi guys,
anyone have a good link to "beginners guide to fittings" ? I get alot of email from people asking what 1/4NPT and G 1/4 mean. I find it a little scary people will try a DIY liquid cooling system without knowing basic plumbing, and would like to offer the best help I can. Thanks, Dave |
i'm not sure dave, but i think one uses a seal and one doesn't. i'm sure people on here will give you a definite answer.

i don't think dave needed help
i think he wants a link to direct other people to |
^ Yes, just looking for a link on a general "guide" to fittings to help newbee's
Thanks for trying to help me anyways, Kaotic. I am an engineer, and hopefully know all about fittings. |

Don't know how to get a direct link to it, but they go over how things are measured, the difference between parallel and tapered and the differences between BSP and NPT. Aaron spink speaking for myself inc. |
I hope this is useful...

(important spec.) G 1/4 Parallel Thread - Nominal Size = 1/4" - 19 Threads per inch http://img232.echo.cx/img232/6788/bsp3eg.jpg Others specs.: Major Diameter d=D 13.157 mm --- Minor Diameter Male Thd. - d3 = 11.445 mm --- Tap Drill Diameter = 11.6 mm --- Included Thread Angle = 55 deg --- Pitch - p = 1.337 mm ------ ------ NPT Tapered Pipe Threads (important spec.) Tapered Threads - Nominal Size 1/4" NPT - 18 Threads per inch http://img96.echo.cx/img96/2777/npt5zw.jpg Others specs.: Taper Angle = 1 deg 47' --- Pipe O.D = 0.540" = 13.716 mm --- --- Included Thread Angle = 60 deg --- Pitch - p = 0.0556" = 1.412 mm |
I think we need something more basic, maybe pictures of NPT and G 1/4 fittings, with details on the pro's and con's
Guess I make something for the C-Systems FAQ sections. Thanks anyways all. |
I'll start you off with BSPT and BSPP
http://www.veryrisky.co.uk/webimages...or_taper_s.jpg BSPT is the taper thread with thread sealant CM. BSPO uses the o-ring to complete the seal, but you can seal it with PTFE table id you don't have an o-ring. I might be able to get a few more together yet. |

Also i think pictures will not show essential difference. |
It migth also be usefull if anyone has links to (pneumatics) fittings suppliers. In the UK I often suggest:
http://www.airlines-pneumatics.com/w...duct-index.asp https://secure.thorite.co.uk/index.html http://www.ihp.co.uk/store/ as well as the big components suppliers http://www.rswww.com http://www.farnell.com/ But I've never found an suppliers accross the water when folks ask for parts links in the US or Canada. |
1/4" NPT Fittings.
Brass fittings, modded by me (thread length trimmed to 8mm and ID Hole to 9mm) http://img228.echo.cx/img228/6489/bicos018rk.jpg Polyamide (Technyl) fitting. http://img228.echo.cx/img228/6563/bicos025ht.jpg Dave, Is there any chance to C-Systems sells plastic fittings (Delrin?) with proper thread length and hose options? G 1/4 - 3/8 barb G 1/4 - 1/2 barb 1/4 NPT - 3/8 barb 1/4 NPT - 1/2 barb By this way, European will be avoid of wrong length threads at G 1/4. |
