You should consider using a thread sealant. Have a look at the product that are available on our website at greggdistributors.ca/adhesives-sealants-and-tape/Thread-and-Gasket-Sealants/Pipe-Sealant?resp_group=Default,Variations,ItemProperties
If you are asking for a live swivel (a swivel that will rotate with minimal torque while fully presurized), yes, Aeroquip have the (AER) FS59004-88-75. If you are asking for a swivel adapter for assembly purposes, yes, part number (AER) 2046-8-8 will do the trick. The 2046-8-8 is a Female NPSM rigid by Female NPSM swivel. If you watched our NPSM video, you will note that NPSM has the same thread as NPTF however the sealing action occurs on the internal chamfer and not the thread. If you are going to use the 2046-8-8 make sure your male NPTF fittings have an internal chamfer to match the female NPSM fittings and you will be all set! You can find both of these fittings in our catalogue on page V126 and V65 (www.greggdistributors.ca/catalogue.php) Hope that helps!
At 8:32 you say due to thread angle difference a true seal is never formed. These are parallel threads so sealing just takes place on seat i thought and not on threads. Please clarify. Thanks?
While the wording may seem somewhat ambiguous, it is correct. You are also correct in your assessment that the sealing takes place on the seat. Having said this, due to the angle differences in the thread you will never be able to thread them together in a fashion that would allow the internal seat to seal. Even though it may feel like the fittings would thread together a true wedging action of the threads would never take place resulting in a leaking fitting.
@@GreggDistributorsLP Hi. Iam am doing a word document to capture the information and pictures in these videos purely for my own benefit so i have a reference of all this info in one place that i can access or print out. Thats why i am asking a few questions. Recently started working in a canning factory where there is a lot of specialised equipment and hydraulics and my knowledge of fittings is weak up to now !! :) Thanks Michael
We stuck with 10 inch NPSM thread seized. Can you pls guide how to avoid seizing during assembly?

Do any manufacturers make 1/2" NPTF x 1/2" NPTF swivels?

at 3:51 this could be a JIC/SAE also ?????
No, it can't be. NPSM is a 30 degree seat whereas JIC is a 37 degree seat.
In the future please turn the background music down.
