Pneumatic Fittings [Archive]

Last night we came to the realization that no piston fittings came in the KOP like they usually did...so off I went in search for some.

After a couple of hours of CD searching and distributor locating that resulted in dead ends, I finally just Google-searched the part number. Whatdya know, the first link gave me what I needed (woot for Google :D ). So for any of the teams who are new to pneumatics (http://forums.usfirst.org/showthread.php?t=10925=), here's a bit to save you some frustration. Perhaps this could form into a sticky if enough info gets posted.

Here's a thread (http://www.chiefdelphi.com/forums/showthread.php?t=68308&highlight=pneumatic+fittings) that tells where to get cheap fittings -- though you need to email them if you want to get them within a few days rather than a couple of weeks (7-10 days processing + shipping time).

There's a thread around here that lists all of the part #'s for the fittings that typically come in the KOP. For the life of me I can't find it...so for now here's a link to purchase the pneumatic elbows that fit into the smaller pistons:

Thanks in advance for any extra info that gets posted!

Other commonly needed pneumatic parts.

Tee fitting:

Basic Black: http://www.alliedelec.com/Search/ProductDetail.aspx?SKU=4990926&MPN=KQT07-00&R=4990926

Straight connector:

Flow control valves:

A few variations available here, e.g., you might want to meter the flow into an actuator vs. out of an actuator.
Last year's was a: NAS2201F-N01-07S
(This translates to: 1/4" elbow, meter-out, one-touch fitting, NPT, 1/8"port, 1/4" tubing, with seal)

Straight screw fitting:
http://www.alliedelec.com/Search/ProductDetail.aspx?SKU=4990012&MPN=KQ2H07-35S&R=4990012
The screw fittings required differ based on the hole in your cylinder, for example, the Clippard storage tank has a 1/4" NPT port, while a typical actuator might use 1/8", and the Bimba rotary actuator requires a tiny connector.

It looks like your source only stocks the 24V coils (we need 12v) on the SMC solenoids, but you can order them from the catalog: http://www.alliedelec.com/Catalog/pf.aspx?FN=1516.pdf
Last year's double solenoid was a: SY3240-6H-S
(This translates to SY3000 series, 2-position single action, base mounting, 12VDC, L-type plug connector, surge suppressor)
The single-action solenoid was a: SY3140-6H-S
Each SMC solenoid also rquires a base: SY3000-27-1T

Parker Plug Valve:

Use "locate a distributor"

Nason Pressure Switch:

Clippard air storage tanks:

1/4" Tubing:
e.g., http://www.alliedelec.com/Search/ProductDetail.aspx?SKU=4991634

In general,
Look for 1/4" tubing fittings.
Solenoids need to have 12v activating coils.
