Seal for SCBA
« on: January 17, 2018, 05:29:40 PM »
Does anyone have a source for the seal that is on the male part of an SCBA tank adpt. looks to be a white nylon ring seated into the stainless probe, or do they make a seal that slips on the end and tightens down in the female seat. Mine leaks after a couple years use. Thanks PM me if need be or e mail.

Thank you , I will get the mike out and measure it up. I was hoping it would be a standard part, no such luck.

It's probably a seal for the Scott valve or whatever brand valve yours SCBA has on it. Both my tanks have the Scott Valves.

Wayne,

The hand tight CGA-347 fittings have an o-ring at the tip of the nipple.  You can see it on the right side of the picture I have attached.  On my hand tight fittings the o-ring is white.

Mine appears to be inserted into the taper/in a slot? I have not pulled it out yet. I will try to post a pic if I can't find a seal. Right now I have a bit of HPA gas tape, Teflon around it,  and it stopped leaking for a while anyway.

I see that has the "Northshore" insignia on it, that's a nice fitting no doubt, if you notice on the pic of my SCBA&Adaptor the bleed valve on the adaptor has the same insignia.  Both my CGA347 adaptors don't have that oring on them but they seal good into the Scott valve but they do need to be wrenched on though.
