Title: Air hose leaks
Post by: oldandslow on March 13, 2021, 12:10:29 PM: Hey folks, trying to set up my air hose.
Got one of them kits from Big Jim.
Its leaking at both ends on those fittings
Maybe I have placed the hose clamps wrong?
I clamped on the large parts and away from the small area in the middle. Thoughts?

I also find it best to wrap the hose about tree times with a heavy cloth, put the hose clamps right next to each other and keep the screws on the clamps away from each other... A little soft soap on the plug may help seal it also...

Post by: oldandslow on March 13, 2021, 12:25:23 PM: I noticed when I pulled that plug it had some hose fiber inside where it sealed. Probably didnt help.
Gonna try your method Shredd

I'm with stic
You need a socket to tighten it up and a bucket of water :thumbsup:
I check mine every time in the bucket of water before glue up

Checking each time is right smart too!

Post by: Mad Max on March 13, 2021, 06:47:29 PM: If you use a hot box to cure the glue, the hose will settle in and stop leaking after 4 or 5 bows.
Just for your Info. 50 to 60 # of air is plenty

Title: Re: Air hose leaks
Post by: JGR1269 on March 13, 2021, 07:26:13 PM: I just put one together last night with plugs and clamps from Big Jim. One clamp on the grooved section and one in the radius section. I also use Blue Monster pipe thread sealant on the valve stem. I aired it up and left it overnight last night and no leaks.

Post by: OldRawhide42 on March 16, 2021, 09:06:29 AM: This is what I use for a little insurance that it does not leak when heating. It makes me feel better.

Post by: BigJim on March 21, 2021, 07:06:59 AM: We don't have to make up new hoses very often, but when we do:

*coat plugs wuith barge cement... sometimes :)
*clamp in concave section and one on the grooved area :)
*tighten clamps with wrench
*Put assembled hose in hot box through a couple of bow heat cycles...

Post by: hunting badger on March 24, 2021, 12:01:41 AM: I always use either silicone or gasket sealer on the plugs, then install in hose and stagger hose clamps, let set for couple of day, test and use. I have found that the heat loosens the clamps over time, so i check mine before every glue up and tighten the hose clamps, just be careful tighten the clamp as you can strip them out!

Post by: Crooked Stic on March 24, 2021, 02:01:26 PM: Permatex makes a aviation gasket sealer kinda do do brown color :bigsmyl: used to use a bunch of it in my mechanic days. prolly seal them hoses really well.
