I will be installing the accessory temp gauge in my '34 I'm restoring. A friend installed one, but has a leak problem where the sensor nipple is installed into the radiator hose. Anyone know the correct procedure for this? I purchased a new copy of the orig. nipple, the stem is made of aluminum. What is best way to seal it? Thanks,

Milt, before installing the fitting, make sure the inside of the hose is clean and smooth. The inside of the hose will be a sealing surface and like any other surface it must be able to accept the fitting pad with no interuption. By the way, I have never seen an aluminum fitting just brass ones. Let me know where you got it.

Keystone,
I was referred to an auto gauge restorer in Arizona, by the name of Stebbins, who purchased the supplies and plans to make the nipple. I purchased it and sent the nipple to another restorer who is just now finishing rebuilding the gauge for the car.

Keystone,or anybody,
Concerning the install of the nipple into the hose, I was told to make the hole withe a heated rod to burn and cauterize the rubber. Do you use silicone or permatex to seal the connection or what?
 
heres the proulbem i had with the nipple from the guy in az it wasent made long enought. when you tighen the nut on the sender bulb it touches the retaining nut on the nipple. thus not squizing the bulb collar tight enought if that is the proulbem you have to remove about a 1/16 of the nut.i carefuly cut a 1/16 off the open end of the nut then removed the small 1/16 piece by cuting & spreading the piece.i had seen this proulbem several times. i work p.t. in a resto shop. i spoke to the guy who makes them & told him. this may not be your proulbem but just play close att to wear the nut is when you tighen it if it touches the nipple retaining nut it will leak .

Richard,
My posted question has to do with the correct way to initially install the nipple in the hose. I will look for the further problem of collision of the retaining nut to the large brass sealing nut. Sealing the connection to the rubber is the question.

Milt, I have installed three brass fittings on some old and some new hoses all without any type of sealant whatsoever with success. I just hate silicon in the cooling system. The first one I did had a heavy duty wire reinforced spiral ribbed tractor type hose and it sealed ok. As far as cutting the hole I just used a small hole saw. I think the best cutter for the job would be a threaded type hole punch that sheet metal guys use. I mount the temp. bulb above the water pump but below the thermostat. I have seen installs above the thermostat but dont understand why. Do you have tetrabromide to fill the gas gauge once you are done?

Keystone,
For the gas gauge, I have purchased the vial of fluid from one of the parts outlets. I have no knowledge where to get the chemical you mentioned by itself. Is the stuff from the parts suppliers bad to use? Should I try to get the tetrabromide?
Thanks for your help.

My experience with liquid from parts supplier was that it all bubbled out. I dont know if the liquid is bad but it might be too light of a specific gravity. This was my first attempt at making a gauge work. Maybe the sender was faulty but it seemed to work for an afternoon only. I want to attempt it again but want to make sure I have the proper fluid. If someone is using parts supplier fluid with success it would be nice to hear from you. Thanks.
 
There was a hole cutter for the hose, it was a dowell with a point in the center (sharpened nail), and a strip of metal like a knife blade screwed to the side.

The hole was slightly smaller than the nipple --the tight fit when clamped by the plates sealed the hose to the nipple.---no "glue" needed

Kurt,
Thanks for the first hand knowledge of the way it was done "in the day".
I can understand a tight fitting hole and the squeezing to make a seal. I know there are a lot of people using a heater feed nipple with little trouble, so this should also be do-able.
Thanks,
