Is it just me?
Or does anyone else find the new style hose seals in plastic a real pain in the butt?
In the past I have never had to apply more than hand tight pressure for the hose end to seal.
I have had to occasionally resort to pipe grips since this new innovation!!!

You`re not the only one grizzly. They also tend to leak if there`s any vibration as there`s very little give in the teflon seal, great fun if you leave the gauges on and do other stuff then come back to find gas hissing out of the connection.

Yes, I prefer the older design too. I find the same problem as Glenn, and often just by twisting themselves 'open' under the weight of a hose hanging off the vertical!

They are ok when new but don`t seem to last to long before they give problems

I think you can swap the teflon seals for the rubber ones, I believe they are the same size.

Are you sure they are not PTFE?

Are you sure they are not PTFE?

Patented by Dupont. Teflon is their trade name for PTFE.

So we are all correct:)
MS I think you may have something there?
But removing the seals may be tricky?
Anybody tried?
Anyone know why they are supplied like this?

Teflon has a nasty habit of flowing (extruding) with use. It also has a fairly 'hard' response, forcing the user to tighten it more, causing more extrusion.

Rubbers are far more forgiving. Who supplies this kind of hose - I'll avoid them like the plague.

I know but we are not allowed to advertise on the board so should avoid trade names:o

But yes you are totally correct they are poor compared to rubber I've lost many a hour vaccing out a system only to see the see hoses not sealing..

For getting the old seals out i remove the depressor and then screw in a wood screw and pull the seal out with pliers. I expect it would work with the teflon ones too.

Hi Jon.
Good to hear from you!
I to have tried to remove the schraeder decompresser from one of these new hoses.
Sadly all that happened was it broke up and I ended with a big piece of swarf left in place.
So as of yet I have yet to succeed!
Has anyone faired better?

I could tell a story of one of those broken depessors going through a brand new scroll comp and making a very nasty noise for about half an hour, but I won't :eek:

Jon :D

The rubber seals do fit as a replcement for the refco teflon seals. Take a bit of getting out though!

Has anyone else been caught out by these hard seals not compressing when they fit their gauges and think "The bloody thing has lost all it's gas.."

Yea they piss me off just recently pulled a vacuum and wanted to be sure the system had no more moisture so left the gauges connected for four hours and came back to find a loos of vacuum after much testing found that the dam Teflon hose seal leaked.
