blast tubes

[moll780]

Are there longer lengths of blast tube available someplace?
I can only find 5/8" x 18" plastic corrugated tubes on Vans site.

Van's did sell a 50' Roll.

States suitable for engine compartment. You could also order scat or skeet tubing for this purpose but I've seen many use the product above.

any advice how to attach this tubing to the baffling? I see nice flanges for 2" scat tubes but no good ideas for the smaller corrugated type.
I'm preparing to swap mags for pMags, hence the need for directed cooling.

I made my own flanges out of fibreglass using an appropriately sized socket from a socket set as a mould.

We did manufacture a 3/4" flange but have discontinued them. Use a Uni-Bit and drill the hole one size smaller in the baffle that the conduit tube then use install the conduit and use a bead of RTV around the conduit to the aluminum to hold it in. It will not go anywhere.

Or you could just skip them.

This sounds workable and super easy.

I wonder if thermoelectric pads would keep them sufficiently cool.
