Hot Rods Heater nipple cap?

Ok. So here's a dumb one. So I have a 5/8 Heater hose nipple that I blocked off. Problem is I used those damn rubber caps and a hose clamp. While it looks alright, it doesn't last, starts to crack and leaks. And it doesn't seem to take verry long. Any better ideas? Something that's not big and clunky? Does any one offer a heavy duty one? Thanks fellas!

 

Is it a threaded nipple ? Put a thd cap,or pull it replace with thd plug.

 

bait well plug?Or use a loop of hose to other heater nipple.

 

Find a brass plug with an Allen head in it. Might have to use a bushing if you can't find a plug big enough.

 

No it's an extra nipple in the radiator. I think it was ment for a heater hose but I'm not using it

 

These are advertised as heater bypass caps, maybe they’re different/better than what you already tried?

 

Make a brass patch and solder it shut.

Use a 1/2" copper pipe cap in a short piece of 5/8" hose..

oh, you said not (dumb) and clunky..

 

Short piece of correct size hose, bolt the fits tight in hose and 2 clamps. Done.

 

I’ll never use the “ heater bypass caps” again. Had one blow up and caused me a roadside repair. I’ll take dumb and clunky if it works

 

If it's an aluminum nipple, just thread it and screw a pipe plug in.

 

I used the same caps that scotty t posted, they last about a year before they crack and leak.

 

One more of us who has had no luck with the rubber caps, so the clunky bolt-in-the-hose deal it is for me. I'm a relocated hillbilly anyway.

 

Yup that's me. Hate the rubber caps that crack. But I'm not liking the bolt in the hose deal.

 

I have been using silicone blanking cap's. Haven't had any more problem's.

 

Liking the solder or plug ideas myself.

 

a bolt in the hose will look much better if you use an allen head bolt instead of a hex head one

 

Or use a chrome allen head bolt.

 

Is there any way you can use it for it’s intended purpose? It was put there for a reason.

 

I looked for something like that but never found any. They should outlast the crappy rubber ones easily.
