a nasco supply exclusive:
why choose
When testing or servicing backflow equipment, you typically need three full sets of adapters — that’s 9 separate pieces.
(3x) ¼” Flare to ¼” NPT
(3x) ½” NPT to accept ¼” NPT
(3x) ¾” NPT to accept ¼” NPT
That’s a lot to carry—and easy to lose.


NASCO's Innovation:
Easier to use and harder to lose.
We're seeing some promising features in the latest training shoes to hit the market.
Streamlined design means less to carry, less to lose, and more peace of mind.

Works seamlessly with ¼”, ½”, and ¾” threaded fittings—no adapters left behind.
Built by plumbers, for plumbers—engineered for real job site demands.
