Metal valve stems question

[hmt81]

I just got my tires & valve stems in from Jake Wilson. The stems they sent do not resemble the photo
in this link http://www.jakewilson.com/productDetail.do?navType=type&webTypeId=321&navTitle=Motorcycle+Tire+Accessories&webCatId=38&keyword=+stem&prodFamilyId=19082

instead the bottom of the valve that sits in the tire is solid, you remove the valve cap, nut, washer & top rubber and insert from inside rim. The unit looks great but it only comes with 1 nut and they are not lock nuts. Did anyone ever use these? Any concern or just use some loc-tite?

I like the design but would prefer two nuts if there was room.

I'd be comfortable with loctight though...

[hmt81]

Yes, my thoughts exactly, but not enough threaded area, guess it's loctite

[Jay]

I have those.  Just a dab of blue locktite.  No problems.

[Lonerbtw]

Thats the same type thay use on race tires. A little bit of spit on the rubber and snug it down good .The rubber will lock the nut so it wont back off.

That style is better than the other one. When the nut is on the inside of the rim, it can't be tightened up if it should work loose. Also the rubber washer is on the outside of the rim which rots after a few years. Your style has no rubber exposed to the elements.

i agree.  i would prefer the style of stem you have pictured.

It looks like two rubber washers in the picture.

One for each side of the wheel?

  I have the same installed.  Here is another pic of the $2 valve stem from Jake Wilson that I have as a spare.  As Ricky-D noted, 2 rubber washers and the one on the inside has a little extension that extends inside the rim.  On the outside of rim another rubber and metal washer then the nut to tighten.



Good product.  probably a good idea to check tightness of nut every now and then.  I don't do that, just make sure it feels secure when checking tire pressure.  Also it is so secure that it doesn't seem necessary to hold finger behind valve stem (like Ricky-D has recommended with OEM) when checking pressure or adding air.

I got these pretty cheap on Amazon, on  a whim...



They seem similar... they are not nearly as heavy as the patchboy ones... and lower
profile... I showed them around at HotGlue's and someone pointed out that they might
hit the clip that the OEM valvestem uses... I guess DonaldCC had no trouble like that?

I like the idea that you don't have to be inside the tire to tighten them

just an observation,  as long as there is presure inside your tire, it will push that plug against the rim of the wheel, so in reality, you don't have to be overly concerned with that nut not being tight.  just like, you can't open the door on an airliner when it's flying at 30,000 feet, the cabin is presurized, pushing the door shut.

Good point about the tire pressure keeping that new type of metal valve stem seated.  I like that new style, as I've heard that slight leaks developed with the older style when the nuts weren't tight enough.  Regardless, either style is a huge improvement over the OEM valves.

As for the airplane door, wouldn't the higher cabin pressure cause it to open if it weren't for the latching mechanism?

[BonS]

In airplanes with pressurized cabins the doors are too big to fit through the opening in the fuselage.  Both the doors and fuselage opening are tapered for a flush fit when closed but the doors bottom out in the tapered openings. That's why the doors open inwardly.

Exactly.  They're called plug type doors and it isn't the altitude that keeps them from opening, its the differential pressure.  You can't open them on the ground until the cabin pressure is dumped.
