Heavy Haul 1″ Flat Face Screw-to-Connect Hydraulic Quick Connect Coupler Set, M52x2 Male Thread, 24° Cone Heavy Series

The Summit Hydraulics 1″ Flat-Face Screw-to-Connect Coupler Set with M52x2 male thread (24° Cone, Heavy Series) is designed for demanding hydraulic systems that require strength, reliability, and a clean operating environment. Constructed from magnetic carbon steel and coated with corrosion-resistant zinc-nickel, it’s built to perform in harsh conditions. The screw-to-connect design allows for quick, tool-free installation, while the flat-face valve helps reduce fluid loss and maintain a cleaner workspace. Its DN25 Heavy Series 24° conical bore ensures a strong, vibration-resistant seal.

With a working pressure of 6,092 PSI and a burst pressure of 16,679 PSI, this heavy haul coupler set provides consistent performance in high-pressure applications. Seals made from Buna-N (NBR), polyurethane (PU), and PTFE deliver excellent resistance to heat, wear, and hydraulic fluid breakdown—making it a rugged, leak-resistant solution for heavy-duty hydraulic systems.
