    NPR 5' Seal Tite hoses.....R410?

    YJ states seal tite connectors should NOT be used on 410. Do you agree and follow that suggestion.

    What is so difficult with manufacturing a seal tite connector that would work safely ?

    I use my seal tight hoses on 410 with no problems. I do 80% refrigeration though....

    NRP's can be used for 410A. I have several YJ ones and I use them for 410A on occasion and I have never had any problems with them.

    iuse both on 410.

    i think some hoses will blow the o-ring out the end with the higher pressures, when you remove the hose end from the schreader.

    Yeah I have ball valve hoses, but with seal tight ends, just less chance of leak and dirt/dust infiltration while riding in the truck. Just like them better.

    I blew out an o-ring on 410. The pressure was somewhere around 600psi.

    the low loss fitting negates the need for the ball valve.....just adding more places to leak. hose ends should always be parked on the manifold when not in use.

    The JB Kobra hoses are designed for r410a pressures. I have had mine for about a month and like them so far.

    I don't like ball valve hoses, I could only get a couple months use out of them before they start leaking. Worthless.

    Mine are well over a year old with no leaks. I've had to change gaskets and depressors a few times, but consider that normal maintenance.

    ^THIS^ is the biggest issue I have with ball valve hoses.

    I don't like to crank the hose fittings down on the hose parks because I don't like changing gaskets and depressors all the time. Because I don't crank them down tight, the hoses fall off of the parks after a fairly short drive and roll around on the floor, picking up all kinds of dirt.

    I leave mine fairly loose at park....but I do check them frequently!

    don't you work on racks?? what's a little bit more crap in the system!?!
