Heavy Haul 5/8″ Flat Face Screw-to-Connect Hydraulic Quick Connect Coupler Set, M30x2 Male Thread, 24° Cone Heavy Series

The Summit Hydraulics 5/8″ Flat-Face Screw-to-Connect Coupler Set with M30x2 male thread (24° Cone, Heavy Series) is built for hydraulic systems requiring strength, durability, and clean operation. Made from magnetic carbon steel and protected with a zinc-nickel corrosion-resistant coating, it performs reliably in harsh conditions. The heavy haul screw-to-connect design enables fast, tool-free setup, while the flat-face valve reduces fluid loss for a cleaner job site. Its DN16 Heavy Series 24° conical bore ensures a secure, vibration-resistant connection.

Rated for a working pressure of 6,092 PSI and a burst pressure of 18,275 PSI, this heavy haul coupler set offers reliable performance under high-pressure demands. Seals made from Buna-N (NBR), polyurethane (PU), and PTFE provide excellent resistance to heat, abrasion, and fluid degradation—making it a durable, leak-resistant solution for heavy-duty hydraulic use.
