NPSF, National Pipe Straight Fuel, is a dryseal straight pipe thread used in fuel and lubrication systems. The tolerances are tight enough that the thread itself seals without needing sealant or a washer, which is why it's specified on fuel lines and similar systems where a bonded seal isn't practical.

Stocked from OSG to DIN 5156, spiral flute, Powder Metal, TiCN coated, for blind holes. All held in UK stock. Order before 4pm and it ships same day.
