Yes I missed the link! Opps. I have worked around pressure pipe all my life and have never used one. I could take a guess but will leave it to someone else that has used them! Interesting to find out my self! Might be the one thing I learn today! :thumbsup: Then I can go back to sleep!

They are used on straight thread with o-ring seals such as cylinders where you need to set an alignment.

Kevin, so.........is this s correct statement.

If a guy uses straight thread fittings, not tapered, but straight, he can use a
Seal Nut to lock the posistion of the straight fitting. The seal nut seals against leakage as well.

Kind of, you cannot just mix and match hydraulic stuff. Look at surplus center or baileys to see all the fittings and application. You can look at Parker also

They are used in a lot of different environment.

ZāGO nuts meet and/or exceed the requirements of environments where gaseous or liquid pressure is a factor and a complete seal is required. ZāGO痴 nuts are also invaluable when a vacuum needs to be created. The nuts are reusable and can be made from numerous combinations of rubber and steel.

I also wanted to know. So I went to the source. Here is what Rick Burke of Discount Hydraulic Hose had to say:

"The seal pipe nut is simply a nut that threads onto a NPT thread and has a plastic sealing ring. This is usually used when a pipe is going through something like a plate."

I know .... it doesn't answer the whole question but it does indicate that it isn't used for sealing fitting unions.

I am still in the dark. I get what J_J has input'd, but what J_J has input'd is not what I linked to. What I linked to at Discount Hoses is a "Seal Nut" , supposedly for use w/ hydralic hoses.

Where does one use that particular style seal nut in direct relation to hydralic hoses? HERE IS A LINK whereas the very first item is a "Seal Nut" on the NPTF fitting page.
