The dash size for posts is 111 I believe.

some internal o-rings for sanke couplers:

Perlick Mk-1 needs 3x #117 for the ID of the coupler body (this may be the same for newer Perlicks)
Taprite "wing" style needs 1x #118 for the coupler body and 2x #115 for the probe.

I also have a coupler which I do not know the brand of (has an "O" stamped in the body). It is similar to the Taprite wing handle, except it has more of a "wheel" handle to operate it. It used the same o-rings as the Taprite wing handle.

PIN LOCK POST O-RING SOLVED!!!

Okay, sorry for the yelling above, but I wanted to get your attention. After I switched my gas lines to reinforced lines and beer lines to 3/16Ē BevSeal (no more beer tasting like water from a garden hose), I developed frequent gas leaks and occasional beer leaks. The reinforced gas lines and BevSeal are much stiffer than the beer/gas lines most use, which caused the fitting to torque and twist. After losing several tanks of CO2, reading this entire post several times and many other posts, I decided to take a hit for the team. Here is what tried:

No. 1. -112 BUNA
No. 2. -112 Silicone
No. 3. 10mm (ID) X 16mm (OD) X 3mm (Diameter) Silicone
No. 4. 12mm (ID) X 17mm (OD) X 2.5mm (Diameter) Silicone
No. 5. 12mm (ID) X 18mm (OD) X 3mm (Diameter) Silicone
No. 6. 10mm (ID) X 17mm (OD) X 3.5mm (Diameter) Silicone

I decided to go with 10mm (ID) X 16mm (OD) X 3mm (Diameter) Silicone for the beer post and 12mm (ID) X 18mm (OD) X 3mm (Diameter) Silicone for the gas post. The inside diameter of Nos. 1 & 2 were too big. The 2.5mm diameter of No. 4 was too small for the groove, and I did not get a snug connection. The 3.5mm diameter of No. 6 was just too thick to fit in the groove.

No. 3 works well on the beer post; it takes a little stretching, but is nice and snug. No. 5 on the gas post is downright tight and takes a little wiggling to get it off. It may be too tight for some. I did not try 11mm (ID) X 17mm (OD) X 3mm (Diameter) Silicone because I could not find them in small quantities, but it is right between the two and may be just right. I also donít know how well BUNA would work. It seems less stretchy to me and might make No. 3 too hard to get on the post and No. 5 too hard to get the connector on post. Iíll leave it someone else to try BUNA and 11mm (ID) X 17mm (OD) X 3mm (Diameter) Silicone.

I ordered small quantities on Amazon from here:
http://www.amazon.com/dp/B008MKXQ9M/..._M3T1_ST1_dp_1 (10 pcs. for $3.49 - 10mm (ID) X 16mm (OD) X 3mm (Diameter) Silicone)
http://www.amazon.com/dp/B008ASY3Y8/...M3T1_ST1_dp_i2 (10 pcs. for $3.47 - 12mm (ID) X 18mm (OD) X 3mm (Diameter) Silicone)
Larger quantities (and the 11x17x3 in silicone) can be purchased at http://www.oringsandmore.com/.

I welcome others to carry the torch from here and post their results. Iíve also attached a few photos.
No. 5 is on the left, a BUNA -111 (agreed ball lock size) in the middle, and No 3 on the right.

Thanks for this. The #5 is tight on the beer post, but would it work ok? Would be nice for folks to just stick with one o ring if possible.

Thanks for the info.
For both the pin lock gas and beer posts I have been using the 10mm (ID) X 16mm (OD) X 3mm (W) for over a year. They work great.

Pin Lock O-Ring Update

I will attempt to use the 10mm (ID) X 16mm (OD) X 3mm (Diameter) BUNA (70 Duro) o-ring.

I ordered a 50 pack from http://www.oringsandmore.com/metric-...ce-for-50-pcs/ for $3.50 (total was $6.25 including first class USPS shipping)

I will let you guys know how these work as soon as they arrive and I have time to test them out!

This is great! I have pin locks and original purchased the 112 for the gas posts- they are a little loose but they seem to be working for me. Next time I buy I will use your guidance.
