these are high temp, high quality silicone couplers. They are made by the same manufacter Greedy, trubonetics, hsk use... as a matter of fact does that label on the "hump" coupler look familiar?

couplers come in most popular sizes 2", 2 1/4, 2 1/2" in red, blue, black.

i realize most peeps on this forum preffer low budget and that is why this is just a test for demand.

at this point i only have the prices on the strait 2 1/2" couplers ($7.00), and that should give you an idea of what the others will be priced at. i will update prices for all sizes tomorow.
