I make DrMini ST brass adaptors. Never rust out like the originals do.
However if plugging it off, a steel plug will work fine.

| Post subject: | Head Coolant Bypass Thread Size |
does anyone know what size thread this pesky little thing is? it appears the nipple that goes into the head for the coolant bypass is so corroded on mine, i cannot get enough purchase on it with a hose clamp... i don't like my fancy new red coolant on the floor i know it's a contentious issue whether to plug this or not. i'm thinking i'll plug it. so what size thread is it? should i use brass or steel plug? does it matter? cheers. |

hmmm, i've been wanting some DrMini porn parts on my car for a while now.... 
Doc, how long is the "barb" for want of a better term, or smooth nipple, on your adaptors? i'm trying to use a wide clamp on a kevlar hose but my old adaptor does not have enough left in it for the clamp to grab on to.... Doc are yours barbed or have a 'bead' on the end? |

Mine are straight, no barbs, I turn them from a BOC gases oxy hose joining nipple. I've never had a leak problem with std rubber 1/2" radiator hose on there. Length of the straight bit (guess) is around 1/2". |
