How to tighten up Perlick 630SS faucets to provide more resistance

[Rev2010]

I've got three new Perlick 630SS faucets and two I simply tightened up the lower and upper nuts a bit to give them a little more resistance opening and closing. By default they felt a little too "feather light" to open and close even under pressure. But, one out of the three stays super light and easy to open/close even if I try to tighten the nuts down with pliers (not going Hulk crazy don't worry). This very faucet, when doing my soda water test in my last thread, has exhibited a weird "after close burst dribble" in that I close the faucet and a few seconds later it let's out a single small stream run then stops and stays fine, it's like a half second. Weird. Anyhow, I liked the extra resistance felt opening/closing the prior back sealing KegCo taps and was just wondering how to adjust these to get that feeling and firmness. Is it incorrect to tighten both nuts down?

This is Perlick's "one diagram for all 600 faucets" diagram.
Ignore the flow control parts.

To tighten the action you only need to tighten down the bonnet (item 2).
Often you need to loosen the handle and then back off the handle jacket (item1) first, then adjust the bonnet as desired.

Tightening the handle jacket down on top of the bonnet should be avoided as they'll bind and wear on each other, not what you're looking for. You should be able to make all the actual action adjustments with the bonnet, then set the handle jacket slightly above and then tighten it to the tap handle.

fwiw, I have a half dozen 525ss which are far more similar than different to the 630ss, and I've never had to use pliers on them.
Which is a good thing as the knurling looks like it could easily be marred...

Cheers!

I just find it weird all three have different action. On one, tightening by hand only I can make the action ridiculously stiff (I don't keep it that way, just saying). On the second hand tightening leaves a good action that feels nice under pressure. The third one feels too loose and easy to move no matter how I adjust it.

This same thing happens to one of my perlicks. I've got 4 of them all the same but one is super easy to use and two I consider normal. The last one takes some force and then does that weird burst thing. I've tried to tighten and loosen the bonnet and nothing changes the feeling.

I just took all of them apart when I was replacing my shanks. Made sure nothing was cross threaded or had an o-ring out of place and still couldn't make much difference to the way certain faucets behaved.

Got it adjusted better, thanks Day_trippr! Turns out I loosened it all and re-tightned first the bonnet than the handle jacket by hand. Still was loose but the plastic tap handle was loosening so I tightened it by hand nice and tight and for some reason that leverage made the tap adjust with a bit more resistance. So it seems good now.

Thanks for the tips on this....6 years later.

I ended up having the same problem with some perlick 630ss faucets and fixed the problem with a little Beer Keg lubricant. The perlicks are only a few months old but one started feeling really restrictive so a little lubricant at the top seal (6) and the front seal (7) really made a difference...smooth operation again.
