Having to keep taps lubed to get free movement doesn't sound right to me - sounds like a band-aid fix to a manufacturing tolerance problem? Maybe they will free up over time once they wear in a bit? As has been mentioned this isn't an issue with the PC's, I've never lubed mine, they've had really nice action from the day I installed them. I'd assume the SS versions 'should' theoretically be the same?
So, I finally got around to testing the taps again. The slight catch on the flow control is real if it's reversed. I don't notice it when the tap is connected and there's pressure in the line.
It's also possible that the tester became intoxicated during the test and the results are flawed.
I agree with Frothie about the taps being good to go from day one. Any stiffness is a design issue.
One thing that does come to mind is the difference between plating and solid stainless. Anyone who's played around with metals and different platings should understand the different properties from each type. Friction plays a massive part along with softness and malleability.
My take on the taps is that they are probably exactly the same as the PC version. The stainless is less slippery than the PC version and you'll just have to wait for the seals to bed in.
In summary:
- Constantly lubricate the taps with plenty of beer and get those seals bedded in.
- Don't be shy with the FC levers. Treat them like they're advertised and report back if the seals fail.
PS.
I've noticed that these taps work quite well by creating a Guinness style head if you are force carbing and taking samples with the FC lever throttled way back. It's probably nothing, but I'm toying with the idea of a nitrogen mix tap on my bar project.
