Brass hose barb for air systems
The SPEEDAIRE 6AFH8 is a straight brass fitting that joins a half-inch push-on hose to a three-eighths-inch male NPT pipe thread. It is built from H59 grade brass and rated for 300 psi maximum pressure. The fitting suits workshop air lines, compressor hook-ups and general pneumatic plumbing.
Crimp or clamp hose connection
A beaded half-inch barb grips the hose while an 11/16-inch hex head provides a positive wrench surface for the NPT end. The crimp or hose-clamp style clamp secures the hose without specialised tools. Straight form keeps the flow path direct and simplifies routing in tight brackets.
Replaces worn or mismatched barbs
Swap out corroded, cracked or wrong-thread fittings to restore a leak-free seal at 300 psi. The jump is worth it when the existing barb no longer holds pressure or when adapting a half-inch hose to a three-eighths-inch port. Not for buyers who need a different barb diameter or a female thread.

Questions about this item
What does the 300 psi limit on the 3/8 inch MNPT end cap in practice?
The 300 psi rating is the maximum working pressure for the brass H59 fitting; exceeding it risks leaks or rupture on the 3/8 inch MNPT connection.
What hose and thread dimensions must match for the 1/2 inch barb and 3/8 inch MNPT to fit?
Use a 1/2 inch ID hose on the barbed end and a 3/8 inch female NPT port; the fitting has an 11/16 inch hex for tightening.
How is the brass hose barb installed, and what step is often missed?
Slide a hose clamp onto the hose, push the hose fully over the 1/2 inch barb, then tighten the clamp; the common mistake is forgetting the clamp.
