CTIS banjo bolt seal

[TomTime]

Coach, I was having difficulty finding a bolt that is not drilled for plugging my spare tire CTIS. I suppose I could find a shoulder bolt, but the army uses a blank banjo bolt. I guess this may be a minor hijack but near to on topic.

The CTIS valve on the spare tire uses a SOLID bolt and nut for storage to hold the seal washers and keep out dirt and debris. That is NOT the banjo bolt that is needed when installing on the truck for service.

Is it a standard bolt or a slick banjo bolt that is not drilled.

A standard bolt will work.

Just an off the shelf bolt and a nut on the other side. Nothing special.

If you're using a nut and bolt you're going to need to use a capped or acorn nut otherwise air can leak along the threads of the nut. A new nylock nut may also seal sufficiently well.

I am just wanting to keep water and dust out of my spares. But, that would do a better job of sealing if the threads are in the sealing washer.

shrink tube. Folk do that over electronic boards in RC cars etc. while hot pinch the end with tweasers or something to melt the end shut. With that in mind you might can heat up a PVC tube ... while hot.... screw it on to thread it. the PVC glue a pipe cap on that. or mayyybe; if you can find a way to hold a hot PVC part, head and thread a PVC cap onto it

Don't make this complicated. The washers seal the sides of the fitting. The threads require additional sealing. You can use Loctite, an acorn nut, a nylock, pipe thread sealant, etc...
