Black Steel Air Fittings

The back-flow prevention valve features a durable brass body with female threads on both ends for easy installation. Its stainless-steel internal seat effectively blocks reverse air flow, preventing the entry of abrasive and dust into the system. Designed for reliability and long service life, this valve ensures smooth, contamination-free operation in blasting and pneumatic systems, offering strong resistance to wear, corrosion, and high-pressure working conditions.
