Stuff?


 

Does anybody know where to get "Stuff?"

I'm talking about the goo that you put in coax connector joins, which fills the void in the connection and seals out any moisture.

A Google search has come up blank.

Automotive silicon dielectric grease works for me.

Next time you see a telephone lineman, ask him for a tube of his line
sealant. Works great. But, be aware, that once sealed, it isn't coming
back apart again.

Hi Alek

Stuff?

You mean Splodge?? I always find that Splodge works better than Stuff.

Alternatively try Tiger Seal or similar from a motor factors.??

OK Thanks Mike and others who replied.

Jerry, WA8R, knew what I was talking about.

The stuff is called "Stuf" and it's made by Cross Devices. See

I have placed an order with RF Parts, for 5 tubes of it.

Cheers and thanks,
Alek.

Indeed Alek, the stuff here is called STUF¡­.. :-)

I can vouch for its efficacy as a stable non-hardening moisture sealant
compound and it works a treat in preserving weather exposed RF connector
internals like new.

I was supplied a toothpaste-style tube of the ¡°STUF¡± stuff some years back
with a Butternut antenna and coaxial hardware bought through HRO. Used
sparingly a tube of the compound lasts a long time!

Thanks Leigh.

Yes, I bought 5 tubes, to share the postage costs, plus I know that the 3 mates who are coming down here to help build and install my Ultrabeam UB50, (if it ever stops raining) will want some. I'll be able to send them home with their own tube, after we've finished and the have polished off all my beer.

Wow, a UB50 beam hey....that antenna will work very nicely!

We just need Solar Cycle 25 to arrive.....you'll be well prepared when it
does.

Hopefully being deployed at considerable height.....I expect to hear a
sonorous signal from VK6 land when pointed easterly toward distant Adelaide!

Filling the connector with a dielectric splodge is certainly a new trick to me.? Even with PL259s I've always just wrapped things in good self-amalgamating tape to waterproof it properly and have rarely had problems with water ingress even here on Rainy Island.? Most water ingress issues I've had have been due to damage to the coax outer jacket.

Still, thanks for the tip.

The real answer is of course to use N-type or 7/16 connectors?

cheers

I use Dow Corning's (Now just Dow Chemical? ... Following merger and buyout)? DC4 dielectric compound.? It is a Silicone grease developed in WWII to seal spark plugs on B17s to prevent arcing at connections at high altitude. It remains a grease (never hardens) EXCEPT when subjected to an arc which causes it to decompose leaving Silicon Dioxide (powdered Quartz) behind as do all brands of Silicon dielectric greases.? It used to be expensive, but with competition the price has come down.
? With Dow buying out Corning's stake it's now just another part of Dow Chemical so I'm not sure what's available.
All their Specialty items including RTVs have become commodities with substantial price reductions.? I retired from DC in 1997 So have little current information.? As I recall, it has an infinite shelf life even after the tube has been opened.
AFAIK all Silicone greases are pretty much the same regardless of who makes it.

Thanks Roger.

My "Stuf" will be arriving in the post today (Monday).

See

I bought 5 tubes of it from RF Parts. Other places were cheaper but they are on drugs with their international postage charges.

I have 3 friends coming to help me set up my new antennas, in two weeks time. Apart from letting them drink all my beer, I will give them each a tube of it to take home.

I? buy....'dielectric grease'? from? local auto parts store. Use? sparingly on? pin of? coax? plugs..and shield threads.? ?Wipe off any? excess.? ?Don't use? it to? fill? air voids,? like on type N? or? 7-16 din.?

I? can't tell? any difference between auto? dielectric? grease and? ?Dow? dc 3/4...? except the? auto? stuff? has? higher? V? stand off.?

I fill all the air voids with DC-4. Twenty years and no water intrusion on a combination of connectors ranging from low band 259s to a UHF array With "N" connectors. I'm either very lucky or it's not a problem.

Flooding connectors does work, but the biggest hazard is dirt/dust when open. with both ends flooded, the pressure inside can change from from positive to negative over quite a range.and this can draw moisture in through tiny faults in the jacket.
My experience has been a little applied to the center pin and threads with a Q-tip and any excess wiped off works quite well
I ran into one ham on FB who complained about having to fix many connectors where "grease" had been used and thought it was a terrible practice.
Maybe he was talking about hydrocarbon based grease, or dirt in the grease?? He never elaborated

There is little difference in the Silicone greases because of the way they are made. The differences between auto and electronic may be the way they are tested. Don't know.

I'm not at liberty to say how they are manufactured, but it's a rather simple process, done in batches AFAIK. At least I know of no continuous processes.
