AAP 3000lb 316 Stainless Hexagon Head Bush, 1" x 1/2"
Available
This AAP hexagon head bush is a 316/316L stainless steel forged fitting with BSPT thread. It is supplied in 6 sizes, 3/4 x 1/2" (20 x 15mm) to 2 x 1-1/2" (50 x 40mm).
A bush reduces a threaded port from a larger size to a smaller one. The size is given as the larger thread first, then the smaller, for example 1/2 x 1/4. A threaded bush is normally male on the outside and female on the inside, and this one has a hexagon head for a spanner. A is its length and B is the width of the hexagon head. The stainless steel high pressure fittings are rated at 3000 lb.
