Thread Sealant

Is 475 gegrees Centigrade or Farenheit?

Or of course Kelvin or Rankin etc....

I use and would recommend after contacting the manufacturer the thread sealant made by Loctite...

John.

Hello

Of course it is 475 centigrade.The problem with Loctite that the curing time is very high and we can not afford wait 24 hour to set.could you suggest other product with details

There are some activators and you have to wait seconds, Permatex® Surface Prep™ Activator for Anaerobics

Speeds cure of Permatex® Threadlockers, Thread Sealants, Retaining Compounds, and Anaerobic Gasket Makers. Recommended for use during cold weather. General-purpose solvent for cleaning and preparing parts and surfaces. Level 1*

To fully understand your question- are you talking about an electrical connector / sealing gland? In that case I would recommend a flange with O-ring. To seal on the thread is not the proper way with a pressure of 250 bar. There are a lot of manufacturers of the such connectors, and you could try one of these:

I had a problem 30 years ago where I had to make a seal on a batch of 1/2" compressed air flexible pipe connections, that cycled over a period of 5 hours between -15psi (vacuum) and 150 psi, and 20C (room temperature) to 200C.

This range is less than yours, but worth a mention, because after many hours of searching through catalogues and phone calls (no internet then) and subsequent testing of various compounds, the one that worked best (for us) believe it or not, was good old-fashioned PTFE tape - the sort sold by plumbers merchants everywhere.

Things might have changed with other materials since then - but the memory lingers on.

Hello

PTFE (Teflon) Tape use for threaded joints is banned and we have to use thread sealant.

We use XPando (www.xpando.com)

• Withstands deflection, high pressures (up to 5000 psig), high temperature (1000°F), low temperature (-300°F),changes in temperatures, and vibrations.

I'll 2nd Expando.

We use it on hydraulic lines that cycle 20 times per minute[0-2000psi], the stuffs really for sealing steam lines. waterbased, a real problem solver!

were can i get expando in 21037 area?

Team Inc. manufactures a wide range of sealants, several of which would meet your needs. Thanks, John Kessinger

We have nearly the same problem, especailly on the stainless steel fittings. We tried Temp-Tite by Jet-Lube but during pressure testing approx. 30% of the connections leaked. The ambient temperature is about 0 C so the curing time described on the container is not practical (24 hours at 150 F).

Did you solve your problem and if so how? Did the xpando as recommended by others work?
