Alex, where are you from? And how about a pic of the insides? That is how I could tell you what I think of them. What a coincidence you and the seller have the same name!! Cool!! I'd say buy them just cuz of that!!

Me the Rc4wd ones. |

Question for people making their own cylinders: What thickess do you use for o-rings? Or what do these ones on the market use?

See it's a new brand, GSK, from Kalinigrad. They are possible not known to anyone here at the forum yet. Great if you buy them and test them out and write a report here. It's positive they are from brass, not aluminium as some of the Chinese ones.

Use 1.5mm thinkness (sometimes 1.78) for the piston and rod seals, 2 off at each location. To seal between the front piece that contains the rod seals, and the cylinder pipe I use also 1.5mm (x1) when enough space. sometimes need to use 1mm here if thigh space. The 1mm seals are more vulnerable for damage when putting the cylinder pieces together, so a more thick seal is better. One need to study the tables for seal groove clearances to get the correct size grooves etc. If one got a 8mm rod, one should not use a o-ring that is exact 8mm inside diameter, but better 7 or 7.5mm max to get a good fit.
