Last year when i did my nitrous instal the main line was alittle short so i made a rubber coated high temp hydraulic line to made up the shortcoming. It seems to have worked fine and doesnt get as cold on the outside as the standard does. Im thinking of going to a 6N hose useing this for the entire line. I can make these hoses for free, thats why im atracted to them. Does anybody else have any experience with these lines?

We ran a hydraulic line in my buddy's 95TA. We had a 15 foot line from the bottle to the solenoid. We took it out because it starting leaking. It would pop like crazy when you turned the bottle on, and it was getting little pinhole leaks all down the line. I would no recomend it.

I don't know if I would. Remember there is about 1000 psi of pressure in the lines.

Well...most hydraulic lines are rated very high. But to really be safe you should know what they are rated for. I have several hyd lines in my setup...all are rated for 3000 psi. 3000psi is fairly standard for hyd equipment.

these are rated at 3000# working pressure and say "high tempreature" on them. I guess i was worried about the cryogenic affects on the hoses more than anything.

383LQ4SS: how long have the hoses your using been in service?
Thanks for the replies

It doesn't matter if the hyd line is high temp or not. The N2O is cold. Just make sure you have double braided hose and not single braid. The plastic coated line you have is single braid. And don't use reuseable fittings. Use crimp only. If it's Weatherhead hose, use the H42506 for 6AN. Straight fittings are 06U-606.

It is double braded with crimp fittings

Mine are Aircraft hyd lines. They have been in service for years before I got them. A few are almost new.They have Aeroquip reusable fittings. The kind you need a mandrel to get them together or apart. I make the at work once in a while. After they are made they are tested to a certain percentage higher than what they are rated for...like 4500 psi. I actually like the non crimped ones..only because I can repair them.

I believe they are just as strong if not stronger than crimped. You will never see a crimped hyd line on a airplane(unless its a hardline)...all reusable fittings. So they must be fairly strong to be airworthy.
