Diy silicon stopper

[Ward Chillington]

Hey folks...proud cheap bastard here....has anyone had any success with fusing silicon? I want to seal one end of hose with a pinch sort of closure...think a round wedge shape... open on the round side, tapered to a wedge on the other side. The material's high heat tolerance makes it just a little difficult unlike working with typical plastic...

Silicone rubber does not have a melting point, it stays solid until it burns.

It would have to be closed mechanically: metal band, wire, adhesive or a good knot.

so are you wanting to just shut the hose end permanently or have the ability to open and close it?

I'm thinking like a cap like you'd see on a tube of caulk that you could pop on and off of a barb connector.

Man this took alot of searching.
Bru Tuber Gash Slug introduced me to these to control flow on silicon hose for transfers but it will also pinch the hose tight for you.
These are them below

Them metal ones are the ones he uses stainless most likely
