Just curious about the residual sealant when you have to break the fittings apart. Especially the inside threads.

It just turns dry inside the threads (anerobic-lack of air hardens it up).....doesn't cure as hard as regular loctite......can be scratched and blown out ......


Oh Yea....BTW........HAPPY NEW YEAR....!!.......:drink::drink::drink::drink:

not starting anything but this shows that any type of sealant can contaminate a hydraulic system...tape does not have the market cornered on causing posssible system failures...

prudent use of tape (holding back from last thread) is about the same as using paste type sealants/lubricants...

My assumption is...most contaminations of user addressed systems by sealant debris occur when original connector fittings are reworked etc...

...it can be difficult to remove debris from ports on valves that can not be inverted to keep fragments from dropping into the valve bodies...

JMO but if I got the chance...I would vote for all ORB ports on everything like valves, cylinders, pumps etc....and all flare (JIC) on hoses/tubes , QD's etc...

Yes, anything can contaminate hyd oil.....but the "Stringyness of the Teflon Tape" is much more trouble....It doesn't churn up well in the mix....

ORB..JIC..:thumbsup:

well, got to work on the leak and found out it's not my connection but the crimp on the hose itself. Guess the dealer is getting acall tomorrow. It's brand new hose

 

[wdchyd]

Make sure he replaces the hose rather than recrimping..!!

This is what my local shop says to use. I've used it a lot with no problems. It won't gum up the system either. Very easy to use, but a bit pricey. Loctite 545.

Loctite 32429 Hydraulic / Pneumatic Thread Sealant, Pack of 2
