3/8 flush socket pipe plug belongs to the scarce 7/8T taper series, with a shorter overall length than the shared 3/4T size. The flush-seating series is useful when surrounding parts or covers leave little room above the plugged port.
Pump and gearbox housings use pipe plugs to close drain, fill, inspection, or machining ports after assembly. Since 1962, Cold Headers has helped buyers locate uncommon internal-hex plug variants such as this 7/8T series.
