I use a .22 caliber wire cleaning brush on the hp hose fitting and the transmitter or gauge. Even a small amount o harden lubricant or salt corrosion can cause bubbles on freshly changed and lubed hp spools.

The solution is clear. Attach the transmitter to a 22" hose. Of course to keep it from flailing around you'll need to tie on a bolt snap and secure it to a hip d-ring.I have some normal length hp hoses that have quite a number of years behind them and they ate still going strong, but the short hoses are not giving me any luck. The one that is leaking today is only a year old (+/- a few months).

Again I ask:
Do I see an o-ring on the transmitter fitting? Should it be there when using a hose?
If replacing the seals don't work, try a different type of spool. There are a few different types of spools-you may just have to find the correct one.
Maybe consider just attaching the TX directly onto the first stage without the hose? I've had mine directly attached for years with no problem.
I use mine directly on the second stage, I used a hose only on a Kraken DH because lack of clearance. Generally no one but me handles my gear. Just my opinion and of course there are always exceptions, I think the fear of someone lifting by the transmitter is way over blown.My concern with attaching it directly to my first stage is 2 fold:
1. I am concerned that someone might try lifting my tank by grabbing the transmitter as upon a quick glance by the uninformed it looks similar enough to a valve handle.
2. I am concerned that in transit and storage the rigid connection between the transmitter and 1st stage would make it more prone to possible damage....having a flexible connection makes this less likely in my mind to be a problem...I also realize that the transmitter can and probably should be removed in transit/storage but constant removal and installation cannot be good either, plus I am lazy and figured that having a flexible hose would be a good compromise.
