Surefire U2 came with no lube

I just got my Surefire U2 Ultra and the threads on the head were completely dry. The selector ring is also pretty hard to twist. Should I take the ring off and lube myself or send back to surefire? Thanks

SureFire ships every light without threads. If the sleector ring works properly but is a little stiff, I doubt you will be able to RMA it.

Think he meant "threads lubed"...

surefire always use lube on their threads, its just a matter of dryness.
wipe it down with alcohol...usually you'll receive some residue on your cotton ball

On pretty much every light I buy, one of the first things I do is give the threads a good brushing with an old toothbrush, and relube with "Nylogell 760". My U2 also has a stiff selector ring. Does anyone have tips for lubing the ring?

My U2 came with sufficient lube, but I did notice the selector ring was a bit stiff.

The ring loosened up with regular use, to where it now feels about perfect. Perhaps a little breaking in is needed?

Try it with "White Lightning" (from a bike-shop).

It works wonderful and the action is very smooth.


:wave:

Be careful. White Lightning is now a brand name for a line of bike maintenance items but some contain petroleum products which can damage some o-rings. Blitzlicht65 probably meant their wax based chain lubricant but always search for an MSDS (Material Safety Data Sheet) before using a product. An MSDS will contain a list of ingredients and safety haards.

This isn't the "end all, be all" but it's a place to start on maintenance -- it's one of a list of relevant threads in a sticky at the top of the General Flashlight section. Lubrication of threads and o-rings

Oh, sorry. I don't know this is a brand name now.?

I mean the wax based type.

The wax based type is liquid, so you need only a few drops.

I've had White Lightning for many years in use without problems at the O-rings.

(There is one O-ring under the selector ring, one split ring and a magnetic spacer to change the levels - no electronics which can be damaged.)

I knew that bringing up lube was like opening a can of worms guys... But thanks for the suggestions. I could go over to my bike shop and look for some white lightning.

the selector ring moves around a piece of magnet that is magnetically tied to an internal magnet...so I do not see any foreseeable issues using petrol based products on the selector ring.

I thought that surefire used Nyogel 760 on their lights, so it wouldn't really be necessary to clean them first, would it?

no comment!

The OP was commenting on the absence of lube on the light, not what type of lube to put on it. He was asking whether or not he should return the light or deal with it himself. If this turns into yet another "I always use xxxx, haven't had any problems" type of thread, it will be closed.

okay okay! you don't have to shout :duck:

nirvanaxp, were you able to solve your problem?

Lube it yourself.

Eventually all lights need new lube anyway.

I hate it when you pop open the box and you dont have any lube:whoopin:

No flashaholic would hope to be that unprepared!
That's like going to a frat party without a spare rubber [for me, a functioning spare tire for the car :shrug:]
