Stainless Steel Flareless Male Connector — IMPA 734301-734314

Stainless steel flareless male connectors in the IMPA 734301–734314 range are specified for high-pressure fuel, hydraulic, and instrumentation lines on board cargo ships, container vessels, tankers, and offshore support vessels. They are found in engine-room fuel injection systems, steering-gear hydraulics, compressed-air panels, and the precision gas-analysis sampling lines that demand leak-tight joints. The flareless bite-type design eliminates flare cracking and re-torque issues common with flared fittings, solving vibration loosening and high-pressure weepage in continuously operating machinery.

Each connector is machined from SUS316 stainless steel for resistance to seawater chloride attack, fuel additives, and hydraulic fluids. The series covers 14 individual IMPA codes (734301–734314) with JIS PT tapered pipe threads and JIS PF parallel threads for pressure-gauge connections. Working pressure is rated at 210 kgf/cm² with a 850 kgf/cm² proof test, making the range suitable for vacuum service and high-precision gas analyzer circuits as well as extreme high/low-temperature marine environments.
